Abstract 

Objective

To compare the efficacy of rectally administered misoprostol with intravenous oxytocin infusion in preventing uterine atony and blood loss during cesarean delivery.

Methods

In this prospective, randomized, double-blind trial, 200 women undergoing cesarean delivery who did not have risk factors for postpartum hemorrhage were randomly allocated to receive either 800µg of rectal misoprostol at the time of peritoneal incision or an intravenous infusion of oxytocin after delivery of the neonate. Primary outcome measures were estimated amount of intraoperative and postoperative (8hours) blood loss and changes in hemoglobin levels 24hours after delivery.

Results

A total of 96 and 94 women were analyzed in the misoprostol and oxytocin groups, respectively. Intraoperative and postoperative blood loss was significantly lower in the misoprostol group than in the oxytocin group (503 vs 592mL, P=0.003 and 74 vs 114mL, P=0.045, respectively). The incidence of shivering was higher in the misoprostol group (8.3% vs 1.1%, P=0.018; RR 7.83; 95% confidence interval, 0.99–61.42).

Conclusion

Rectal misoprostol appears to be an effective alternative to intravenous oxytocin in preventing blood loss for routine use during cesarean delivery. Clinical Trials Registration: CTRI/2009/091/000075.
