文摘

To determine whether buccal misoprostol during cesarean delivery in conjunction with active management of the third stage of labor reduces the need for additional uterotonic drugs.

Method

A double-blind, randomized, placebo-controlled trial was performed in Monterrey, Mexico, between February 2008 and December 2013. Eligible women had risk factors for uterine atony and were to undergo cesarean delivery under epidural block. Using a computer-generated sequence and blocks of six, patients were randomly assigned to receive 400 μg misoprostol or 800 μg placebo buccally after cord clamping. Both groups received an intravenous oxytocin infusion. The primary outcome was the need for additional uterotonic drugs. Analyses were performed per protocol. Patients, investigators, and data analysts were masked to group assignment.

Results

A total of 120 women were included in analyses (60 in each group). At least one additional uterotonic drug was required in 24 (40%) women in the placebo group versus 6 (10%) women in the misoprostol group (relative risk 0.16; 95% confidence interval 0.06-0.44). No adverse effects due to misoprostol were recorded.

Conclusion

Buccal misoprostol during cesarean delivery reduced the need for additional uterotonic drugs to treat uterine atony.
