A comparative study between preoperative rectal misoprostol and intraoperative intrauterine administration in the reduction of blood loss during and after cesarean delivery: A randomized controlled trial.

OBJECTIVE To compare the efficacy and safety of rectal misoprostol with intrauterine misoprostol in the reduction of blood loss during and after cesarean delivery. METHODS Ninety-eight pregnant women, all candidates for elective cesarean delivery, were equally randomized into two groups: the rectal group (received preoperative misoprostol rectally) and the intrauterine group (received intrauterine misoprostol after the delivery of the placenta). The primary outcome was the estimated blood loss (EBL) during cesarean delivery. Secondary outcomes included the occurrence of excessive blood loss (>1000 mL) within the first 24 hours postoperatively and the occurrence of any maternal or fetal side effects. RESULTS There were no statistically significant differences between the two groups regarding either the EBL (693.12±139.09 vs 692.39±132.83; P=0.979) or the occurrence of postpartum hemorrhage (>1000 mL) (6.1% vs 4.1%; P=0.99. Apgar scores at 1 and 5 minutes were significantly higher in the intrauterine group compared to the rectal group. CONCLUSION Insertion of intrauterine misoprostol is as effective as rectal insertion in reducing blood loss during and after cesarean delivery; however, it has a safer neonatal outcome and is more convenient when administered during cesarean delivery.
