KOEN, S; SNYMAN, L C; PATTINSON, R C  y  MAKIN, J A. A randomised controlled trial comparing oxytocin and oxytocin + ergometrine for prevention of postpartum haemorrhage at caesarean section. SAMJ, S. Afr. med. j. [online]. 2016, vol.106, n.4, pp.399-402. ISSN 2078-5135.  http://dx.doi.org/10.7196/SAMJ.2016.V106I4.10133.

BACKGROUND: Globally 166 000 women die annually as a result of obstetric haemorrhage. More than 50% of these deaths occur in sub-Saharan Africa. Uterine atony is the commonest cause of severe postpartum haemorrhage (PPH). Bleeding at or after caesarean section (CS) is responsible for >30% of maternal deaths due to obstetric haemorrhage in South Africa (SA OBJECTIVE: To compare oxytocin alone with oxytocin + ergometrine in terms of primary prophylaxis for PPH at the time of CS METHODS: This was a double-blind randomised controlled interventional study comparing oxytocin with oxytocin + ergometrine administered during CS. Patients were randomised to receive oxytocin alone intravenously as a bolus or oxytocin + ergometrine intramuscularly, with the placebo being an injection of sterile water. The study population consisted of women undergoing CS at Kalafong Provincial Tertiary Hospital in Atteridgeville, Gauteng, SA RESULTS: Five hundred and forty women were randomised and data for 416 women, of whom 214 received oxytocin and 202 oxytocin + ergometrine, were available for analysis. In the oxytocin group 19 women (8.9%) required blood transfusion, compared with seven (3.5%) in the oxytocin + ergometrine group (p=0.01; relative risk = 2.78; 95% confidence interval 1.21 - 6.4). There were no statistically significant differences in the mean estimated visual and mean calculated blood loss CONCLUSIONS: The overall need for blood transfusion was significantly reduced by about two-thirds in women receiving the oxytocin + ergometrine combination. Consideration should be given to using oxytocin + ergometrine for prophylaxis of PPH at CS
