Summary: A randomized controlled study of 112 women with singleton pregnancies at term, and no antenatal complications, admitted in spontaneous labour were randomized to receive either an intramuscular injection of 0.5 mg of Syntometrine or an intramuscular injection of 125 ug of prostaglandin 15‐methyl F2 alpha at delivery of the anterior shoulder of the baby. Blood lost in the first 2 hours, and subsequent 22 hours postdelivery were collected separately and measured by colourimetric measurement of haemoglobin content. Other parameters in the third stage were measured, including need for transfusion of blood or blood products, length of the third stage, and change in haemoglobin concentration before and 24 hours after delivery. The incidence of side‐effects with administration of either prostaglandin 15‐methyl F2 alpha or Syntometrine were documented. The prophylactic use of intramuscular prostaglandin 15‐methyl F2 alpha (Carboprost) in the active management of the third stage of labour gave similar results to prophylactic intramuscular Syntometrine in terms of length of the third stage of labour, incidence of postpartum haemorrhage and total blood loss in the first 2 hours and subsequent 22 hours after delivery. However it has the disadvantage of higher cost, as well as statistically significant increase in the incidence of profuse and frequent diarrhoea. Based on these results intramuscular injection of prostaglandin 15‐methyl F2 alpha offers no advantage over intramuscular Syntometrine for routine prophylactic use to reduce blood loss in the third stage of labour.
