SAVING MOTHERS REPORT FOR SOUTH AFRICA, 2005 – 2007

OBSTETRIC HAEMORRHAGE • Accounted for 491 maternal deaths in South Africa

during 2005 – 2007. (12.4% of total deaths and the third most common cause of maternal death)

• Most common causes of haemorrhage deaths were: APH: Abruptio placentae PPH: uterine atony (prolonged labour) retained placenta ruptured uterus bleeding associated with caesarean section

Haemorrhage is oftenHaemorrhage is often not not recognizedrecognized

Blood loss is underestimated because in pregnancy Blood loss is underestimated because in pregnancy signs of hypovolaemia do not show until the losses are signs of hypovolaemia do not show until the losses are largelarge

This is because mother compensates for blood loss by This is because mother compensates for blood loss by shutting off the blood supply to the fetoplacental unitshutting off the blood supply to the fetoplacental unit

Mother can lose up to 35% of circulating blood volume Mother can lose up to 35% of circulating blood volume (2000 mls) before showing signs of hypovolaemia(2000 mls) before showing signs of hypovolaemia

Haemorrhage – stop the bleedingHaemorrhage – stop the bleeding• Good history and systematic examination to

determine cause

• CALL for help: Resuscitation and diagnosis of cause of bleeding plus treatment must occur concurrently.

• How to stop bleeding for most causes will be covered in breakout sessions

• Stepwise approach in case of uterine atony

Oxytocic agents for treating uterine atony

Drug Dose Max dose Further doses

Cautions

oxytocin IM; 10 unitsIV; slowly 2.5units

IV; infusion 20-40iu/ Litre

Avoid >3 litres of fluid containing oxytocin

IV bolus

ergometrine IM: 0.5mgmsIV: 0.2mgms

Repeat dose after 15 minutes

Total 1.0mg Hypertension, pre-eclampsia, heart disease

misoprostol 400-600mcgms sublingual or rectal

pyrexia

PGF2alpha Intramyometrial; 5mgms in 10 mls saline. Give 1ml

Repeat dose after 10 mins.

Total 2.0 mgms (4 doses)

Asthma, do not give IV

Page 14: Obstetric Haemorrhage

Treatment of PPH from other causes• Retained placenta…. Manual removal. (Efficacy of

Intraumbilical cord oxytocin injection not proven)

• Suspected retained placental products…. uterine evacuation under anaesthesia

• Cervical and vaginal trauma…..Repair with good light/ understanding of the anatomy.

• Ruptured uterus ….Laparotomy

• Unknown cause…Early recourse to Examination under Anaesthesia and possible laparotomy
