Uterotonics in elective caesarean delivery: a randomised non-inferiority study comparing carbetocin 20 μg and 100 μg.

Postpartum haemorrhage is the leading cause of maternal mortality worldwide and prophylactic uterotonic drug administration after the delivery of the infant is advised. Carbetocin is recommended as an uterotonic, but the minimum effective dose has not been verified. We compared the efficacy of two doses of intravenous carbetocin (20 μg and 100 μg) in women undergoing elective caesarean delivery.
