Blunt liver trauma The liver is the most frequently injured solid organ
following blunt abdominal injury in children
Selective non-operative management of blunt liver trauma
in haemodynamically stable patients is well established
and accepted by most paediatric surgical centres
Surgical intervention in paediatric liver trauma is based on
haemodynamic instability that persists despite ongoing
resuscitation
Biliary injuries are often missed until clinically manifest
Major liver trauma is still associated with a significant
mortality
Patterns of liver injury ]
Peritoneal and vascular fixed attachments

The direction velocity grade and site of blunt force as well as the position
and motion of the victim contribute to the pattern and severity of the injury

Natural History of different types of injury
Retroperitoneal area ndash tamponade but hepatic vein may bleed ++
Glissonrsquos capsule intact + bleeding ndash expanding subcapsular haematoma
Haematoma contained within the liver parenchyma - expansion amp liquefaction
- absorption 2 to 3 months
- infection ndash abscess
- encysted
Arterial rupture ndash expansion on-going bleeding
- pseudoaneurysm amp delayed bleed or haemobilia
- arterio-portal fistula - peripheral most close
- central may lead to portal hypertension
Bile duct - partial will heal if distal duct intact
but may require intra-ductal pressure reduction for this to occur
- larger - on-going leak and bile ascites
- stricture
- biliary fistula if duct from a segment disrupted but otherwise viable

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

found to have a grade 45 laceration to the Right Hepatic lobe
Intra-operative resuscitation with 45mlkg of packed red cells
FFP and damage control surgical techniques in-flow control
(Pringle manoeuvre) and liver packing with abdominal
swabs were instituted rFVIIa (120 KIU) was administered in
order to secure adequate haemostasis The patient made a
successful recovery after re-look laparotomy in 48hrs to remove
abdominal packs
Retro-hepatic IVC haemorrhage
1 Transverse incision with midline cranial extension
2 Packing of the liver and volume resuscitation with
Rapid Infusion System prior to vascular isolation
3 Isolation of the intra-pericardial vena cava through a
trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving
Blunt liver trauma The liver is the most frequently injured solid organ
following blunt abdominal injury in children
Selective non-operative management of blunt liver trauma
in haemodynamically stable patients is well established
and accepted by most paediatric surgical centres
Surgical intervention in paediatric liver trauma is based on
haemodynamic instability that persists despite ongoing
resuscitation
Biliary injuries are often missed until clinically manifest
Major liver trauma is still associated with a significant
mortality

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Retro-hepatic IVC haemorrhage
1 Transverse incision with midline cranial extension
2 Packing of the liver and volume resuscitation with
Rapid Infusion System prior to vascular isolation
3 Isolation of the intra-pericardial vena cava through a
trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving

Natural History of different types of injury
Retroperitoneal area ndash tamponade but hepatic vein may bleed ++
Glissonrsquos capsule intact + bleeding ndash expanding subcapsular haematoma
Haematoma contained within the liver parenchyma - expansion amp liquefaction
- absorption 2 to 3 months
- infection ndash abscess
- encysted
Arterial rupture ndash expansion on-going bleeding
- pseudoaneurysm amp delayed bleed or haemobilia
- arterio-portal fistula - peripheral most close
- central may lead to portal hypertension
Bile duct - partial will heal if distal duct intact
but may require intra-ductal pressure reduction for this to occur
- larger - on-going leak and bile ascites
- stricture
- biliary fistula if duct from a segment disrupted but otherwise viable

control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Patient A a 20kg seven year old male presented to the trauma
unit in June 2009 following a motor vehicle accident He had
sustained blunt abdominal trauma as well as a fractured right
femur He had unresponsive Grade 4 Haemorrhagic shock
mandating an emergency laparotomy At laparotomy he was
found to have a grade 45 laceration to the Right Hepatic lobe
Intra-operative resuscitation with 45mlkg of packed red cells
FFP and damage control surgical techniques in-flow control
(Pringle manoeuvre) and liver packing with abdominal
swabs were instituted rFVIIa (120 KIU) was administered in
order to secure adequate haemostasis The patient made a
successful recovery after re-look laparotomy in 48hrs to remove
abdominal packs

trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving
Patterns of injury Oblique right chest [pedestrian traffic]

Natural History of different types of injury
Retroperitoneal area ndash tamponade but hepatic vein may bleed ++
Glissonrsquos capsule intact + bleeding ndash expanding subcapsular haematoma
Haematoma contained within the liver parenchyma - expansion amp liquefaction
- absorption 2 to 3 months
- infection ndash abscess
- encysted
Arterial rupture ndash expansion on-going bleeding
- pseudoaneurysm amp delayed bleed or haemobilia
- arterio-portal fistula - peripheral most close
- central may lead to portal hypertension
Bile duct - partial will heal if distal duct intact
but may require intra-ductal pressure reduction for this to occur
- larger - on-going leak and bile ascites
- stricture
- biliary fistula if duct from a segment disrupted but otherwise viable

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving
Natural History of different types of injury
Retroperitoneal area ndash tamponade but hepatic vein may bleed ++
Glissonrsquos capsule intact + bleeding ndash expanding subcapsular haematoma
Haematoma contained within the liver parenchyma - expansion amp liquefaction
- absorption 2 to 3 months
- infection ndash abscess
- encysted
Arterial rupture ndash expansion on-going bleeding
- pseudoaneurysm amp delayed bleed or haemobilia
- arterio-portal fistula - peripheral most close
- central may lead to portal hypertension
Bile duct - partial will heal if distal duct intact
but may require intra-ductal pressure reduction for this to occur
- larger - on-going leak and bile ascites
- stricture
- biliary fistula if duct from a segment disrupted but otherwise viable

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Patient A a 20kg seven year old male presented to the trauma
unit in June 2009 following a motor vehicle accident He had
sustained blunt abdominal trauma as well as a fractured right
femur He had unresponsive Grade 4 Haemorrhagic shock
mandating an emergency laparotomy At laparotomy he was
found to have a grade 45 laceration to the Right Hepatic lobe
Intra-operative resuscitation with 45mlkg of packed red cells
FFP and damage control surgical techniques in-flow control
(Pringle manoeuvre) and liver packing with abdominal
swabs were instituted rFVIIa (120 KIU) was administered in
order to secure adequate haemostasis The patient made a
successful recovery after re-look laparotomy in 48hrs to remove
abdominal packs
Retro-hepatic IVC haemorrhage
1 Transverse incision with midline cranial extension
2 Packing of the liver and volume resuscitation with
Rapid Infusion System prior to vascular isolation
3 Isolation of the intra-pericardial vena cava through a
trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving

several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Patient A a 20kg seven year old male presented to the trauma
unit in June 2009 following a motor vehicle accident He had
sustained blunt abdominal trauma as well as a fractured right
femur He had unresponsive Grade 4 Haemorrhagic shock
mandating an emergency laparotomy At laparotomy he was
found to have a grade 45 laceration to the Right Hepatic lobe
Intra-operative resuscitation with 45mlkg of packed red cells
FFP and damage control surgical techniques in-flow control
(Pringle manoeuvre) and liver packing with abdominal
swabs were instituted rFVIIa (120 KIU) was administered in
order to secure adequate haemostasis The patient made a
successful recovery after re-look laparotomy in 48hrs to remove
abdominal packs
Retro-hepatic IVC haemorrhage
1 Transverse incision with midline cranial extension
2 Packing of the liver and volume resuscitation with
Rapid Infusion System prior to vascular isolation
3 Isolation of the intra-pericardial vena cava through a
trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

found to have a grade 45 laceration to the Right Hepatic lobe
Intra-operative resuscitation with 45mlkg of packed red cells
FFP and damage control surgical techniques in-flow control

abdominal packs
Retro-hepatic IVC haemorrhage
1 Transverse incision with midline cranial extension
2 Packing of the liver and volume resuscitation with
Rapid Infusion System prior to vascular isolation
3 Isolation of the intra-pericardial vena cava through a
trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury

trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage

Patient A a 20kg seven year old male presented to the trauma
unit in June 2009 following a motor vehicle accident He had
sustained blunt abdominal trauma as well as a fractured right
femur He had unresponsive Grade 4 Haemorrhagic shock
mandating an emergency laparotomy At laparotomy he was
found to have a grade 45 laceration to the Right Hepatic lobe
Intra-operative resuscitation with 45mlkg of packed red cells
FFP and damage control surgical techniques in-flow control
(Pringle manoeuvre) and liver packing with abdominal
swabs were instituted rFVIIa (120 KIU) was administered in
order to secure adequate haemostasis The patient made a
successful recovery after re-look laparotomy in 48hrs to remove
abdominal packs

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

The use of Recombinant Activated Factor VII in Damage-Control Surgery for Abdominal Trauma
RJ Wood CJ Westgarth-Taylor H van Niekerk O Hodges J Thomas AJW Millar Department of Paediatric Surgery and Anaesthesia Red Cross War Memorial Childrenrsquos Hospital
University of Cape Town
Introduction
Recombinant FVIIa (NovoSeven) was developed for use in the treatment of severe haemophilia complicated with
inhibitors against FVIIIFIX (1) It has subsequently been used successfully in treating massive haemorrhage
following cardiac surgery in non-haemophilia patients (2 3) Few studies have looked at the use of rFVIIa in
paediatric non-haemophiliac patients We present 2 cases in which it has been used in conjunction with damage
control surgery in the treatment of unresponsive Haemorrhagic shock following blunt and penetrating abdominal
trauma in paediatric patients at the Red Cross War Memorial Childrenrsquos Hospital
Mechanism of action
Discussion
Case A Patient A a 20kg seven year old male presented to the trauma unit in June 2009 following a motor vehicle
accident He had sustained blunt abdominal trauma as well as a fractured right femur He had unresponsive
Grade 4 Haemorrhagic shock mandating an emergency laparotomy At laparotomy he was found to have a grade
4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

4 laceration to the Right Hepatic lobe Intra-operative resuscitation with 45mlkg of packed red cells and damage
control surgical techniques in-flow control (Pringle manoeuvre) and liver packing with abdominal swabs were
instituted rFVIIa (120 KIU) was administered in order to secure adequate haemostasis The patient made a
successful recovery after relook laparotomy in 48hrs to remove abdominal packs
Case B Patient B a 40kg nine year old female presented to the trauma unit in July 2009 after sustaining 2 abdominal
gunshot wounds She had unresponsive Grade 4 Haemorrhagic shock and underwent emergency laparotomy At
laparotomy extensive intra-abdominal vascular injuries were found She had sustained a through and through
injury of the inferior vena cava and left iliac vein Damage control techniques were employed and both vessels
were ligated Intra-operative resuscitation included 100mlkg packed red cell transfusion as well as 15mlkg of
fresh frozen plasma and 15mlkg of platelets rFVIIa was administered intra-operatively and satisfactory
hemostasis was secured The patient made a successful recovery after a prolonged ICU stay
The management of unresponsive and transiently responsive Grade 3 amp 4 Haemorrhagic shock usually requires
surgical haemorrhage control Abbreviated Laparotomy and Damage control techniques are well established in
adult and paediatric practice(7) Major haemorrhage and extensive fluid resuscitation leads to dilution of
coagulation factors platelet dysfunction and impaired production of clotting factors because of tissue hypoxia
caused by hypotension Acidosis and hypothermia further aggravates coagulopathy The use of rFVIIa in adult
patients undergoing surgery has been extensively reported but large randomized controlled trials are lacking (3)
Fewer reports are available on its use in the paediatric patient group but reports indicate that rFVIIa could
significantly decrease blood-product administration (2 4) Although expensive the cost must be balanced against
the potential risk of transmission of blood-borne pathogens the cost of surgery and the cost of blood and plasma
products (4) While rFVIIa may be extremely useful it can only be used in conjunction with timely surgery and
resuscitation after correction of Acidosis and Hypothermia (1 5) Recommended target blood levels before
administration are hematocrit gt24 fibrinogen gt05 to 1 gL platelets gt50 to 100000 times 109L and pH ge72 (5)
Coagulopathy in the trauma patient is a complicated condition with numerous role-players (as outlined above)
several protocols advocating specific transfusion ratiorsquos (RBCFFPPlt) have been published (6) The role of
rFVIIa in resuscitation protocols needs to be clarified and large trials are needed to elucidate this

Retro-hepatic IVC haemorrhage
1 Transverse incision with midline cranial extension
2 Packing of the liver and volume resuscitation with
Rapid Infusion System prior to vascular isolation
3 Isolation of the intra-pericardial vena cava through a
trans-diaphragmatic pericardial window
4 Control the suprarenal vena cava and porta hepatis
5 Repair of vein lacerations with vascular occlusion amp
continuous saline irrigation for improved visualization
Conclusions Contrast blush on initial CT scan is a useful indicator of
ongoing haemorrhage and the need for urgent
laparotomy or angiographic intervention
Bile duct injuries are more frequently seen in the select
group of children suffering severe liver trauma
TBIDA scan is a sensitive investigation for bile duct
injury in severe liver trauma in children
Adjunctive procedures such as angiography and
embolization play an essential role in treating vascular
injuries
The challenge is to identify early the severe injury
requiring immediate life saving surgical intervention
Factor VII and packing can be life saving
