The effect of post-cesarean rectal misoprostol on intestinal motility

Abstract Objective To determine whether rectally administered misoprostol can induce intestinal motility compared with oxytocin infusion when used to prevent primary postpartum hemorrhage after cesarean delivery. Methods In a prospective randomized double-blind study in Nigeria, 218 parturients undergoing cesarean delivery who had risk factors for primary postpartum hemorrhage were enrolled between July 1, 2010, and March 31, 2011. Participants received 600 μg of rectal misoprostol or 20 intravenous units of oxytocin for 4 hours after surgery. The primary outcome was time until passage of flatus. Adverse effects, need for additional analgesic, and length of hospital stay were also assessed. Results The misoprostol group had a significantly shorter mean postoperative interval to passage of flatus (20.27 ± 7.77 hours versus 38.34 ± 10.98 hours; P P Conclusion After cesarean delivery, rectal misoprostol had the added benefit of inducing intestinal motility. Misoprostol might be considered in a clinical setting where postoperative ileus is anticipated.
