COURSE IN THE WARDS

• June 19, 2011• Gave birth via normal spontaneous delivery to a

baby boy• Oxytocin IM• Total blood loss (400-500 cc)

• 10 ”u” of oxytocin - incorporated in IVF• Cefalexin 500 mg/cap q 8° x 7 days • Mefenamic acid 500 mg/cap q 6°, PRN for pain• CXR PA view, Na, K, Cl, AST, ALT, LDH, UA • NPO

• June 20, 2011• Blood loss (300 cc) • Pale palpebral conjunctivae, pale nail beds, and

tachycardiac (110-120 bpm)• Hemoglobin and hematocrit (99, .030)• For emergency hysterectomy secondary to uterine

atony• Ampicillin 2 grams/IV, (-) ANST• 1 unit Voluven

• Underwent emergency Total Abdominal Hysterectomy under subarachnoid block

• Vital signs - stable• 2 units of PRBCs - transfused • Blood loss intra-op - 800-900 cc

• Ketorolac 30 mg IV loading, then 15 mg IV q 6° x 4 doses (-) ANST

• Tramadol 150 mg loading then Tramadol drip 300 mg in 500 cc D5W at 21 gtts/min

• Omeprazole 40 mg IV OD while on NPO• Metoclopramide 10 mg PRN for vomiting• Ampicillin 1 gram IV q 6° (-) ANST• Metronidazole 500 mg IV q 8° x 3 doses (-)ANST• Cconscious and coherent, with pallor. UO -

adequate

• June 21, 2011 and June 22, 2011• Same management

• June 23, 2011• Hemoglobin and hematocrit - slightly below

baseline• Clearance for possible discharge

SALIENT FEATURES • 40 year-old, female• G10P10 (10-0-0-10)• Blood loss of approximately 800 cc• Tachycardic• Pale palpebral conjunctiva• Pale nail beds• Low Hemoglobin and Hematocrit

DIAGNOSIS • G10P10 (10-0-0-10) PUFT, cephalic, delivered

via NSD to a live baby boy with AS 9, Postpartum Hemorrhage secondary to Uterine Atony, S/P Total Abdominal Hysterectomy by Subarachnoid Block

DISCUSSION • Uterine Atony is the failure of the uterus to

contract properly following delivery.

• Failure of contraction and retraction of the myometrium prevents hemostasis and leads to an increase in blood loss.

• Predisposing factors:• high parity• precipitous or prolonged labor• general anesthesia• overdistended uterus (macrosomia, hydramnios,

multifetal pregnancy)• oxytocin augmentation or induction of labor• history of PPH• amniotic fluid embolism• magnesium sulfate in laboring patients• constant kneading and squeezing

• Uterine Atony VS Vaginal Lacerations • based on the condition of the uterus• uterus - soft and boggy following infant and

placental delivery• once uterus is well contracted, but still (+)

bright-red bleeding lacerations

• Complications:• vary, depends on the range of degree of severity• Hypovolemia maternal hypotension, shock, acute

tubular necrosis, dilution coagulopathy, cardiac arrest, and death

• BT-related complications – BT reactions, hemolysis d/t ABO incompatibility, viral diseases (hepatitis & HIV infection), acute lung injury, transmission of bacterial endotoxin, transmission of parasitic agents, graft VS host disease, alloimmunization to blood products, and transfusion-related immunosuppression.

• shock, anemia, infection, kidney failure, or brain damage

MANAGEMENT • fundal massage is indicated • 20 units of oxytocin in 1 L of LR or PNSS, IV, 10

ml/min• oxytocin should never be given as an undiluted

bolus dose as serious hypotension or cardiac arrhythmias may follow

• ergot derivatives: methylergonovine .2 mg, IM• may cause hypertension

• prostaglandin: hemabate 250 grams, IM• contraindicated in asthmatic px•

• if unresponsive to multiple administrations oxytocics:

• bimanual uterine compression and fundal massage• begin blood transfusions• explore uterine cavity manually for retained placental

fragments or lacerations• thoroughly inspect the cervix and vagina after adequate

exposure• add a second large-bore intravenous catheter at the

same time as blood is given• insert a foley catheter to monitor urine output (good

renal perfusion measure)

•

• ligation of arteries• B-Lynch suturing of uterus

• Intractable uterine atony hysterectomy
