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

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

5 Repair of vein lacerations with vascular occlusion amp

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

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

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

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

Patterns of injury Oblique right chest [pedestrian traffic]

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

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

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

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

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

laparotomy or angiographic intervention

Bile duct injuries are more frequently seen in the select

group of children suffering severe liver trauma

injury in severe liver trauma in children

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

injuries

The challenge is to identify early the severe injury

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

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

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

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
