OBJECTIVES: To compare the efficacy of 25 vs. 50 microg of intravaginal misoprostol vs. intracervical dinoprostone for cervical ripening and labor induction.
MATERIALS AND METHODS: 210 women with Bishop's score <6 were randomized into 3 groups of 70 each to receive 6 hourly doses of either 25 or 50 microg of intravaginal misoprostol or 0.5 mg intracervical dinoprostone to maximum of 3 doses and outcome parameters were compared.
RESULTS: Induction to vaginal delivery interval was significantly lower (p < 0.05) for 50 microg (13.8 +/- 6.62 hours) as compared to 25 microg misoprostol (16.4 +/- 7.34 hours) or dinoprostone group (16.3 +/- 7.49 hours). Maximum improvement (p < 0.05) in Bishop's score and minimum oxytocin requirement (p < 0.05) was seen with misoprostol 50 microg. No significant difference was observed for women delivering vaginally within 24 hours (93.8 vs. 89.7 vs. 85.4%), patients delivering after one dose (24.3 vs. 21.4 vs. 20%), cesarean deliveries, fetal outcome, complications like hyperstimulation and fetal heart abnormalities for the 50 vs. 25 microg misoprostol vs. dinoprostone group.
CONCLUSION: Intravaginal misoprostol 50 microg administered 6 hourly appears to be most effective as it has least induction to delivery time, has maximum improvement in Bishop's score, least oxytocin requirement without any increase in complication rate.
