Comparison of Vaginal PGE2 (Dinoprostone) and Vaginal Misoprostol for Induction of Labour in Primigravid Term Pregnancy

This randomized controlled trial was conducted to compare vaginal misoprostol and vaginal PGE2 (dinoprostone) for induction of labour in primigravid women with term pregnancy. Labour induction is commonly required when pregnancy reaches term but spontaneous labour has not started. Different medicines are used to soften the cervix and start uterine contractions, but their effectiveness may vary. A total of 240 primigravid women with singleton pregnancy at 40 weeks or more of gestation, who were not in spontaneous labour and were planned for induction of labour, were included. Participants were allocated into two equal groups. Women in Group M received a 50 μg vaginal misoprostol insert, while women in Group D received a 3 mg vaginal dinoprostone insert. Both medicines were given under aseptic conditions in the inpatient obstetrics setting. The main purpose of the study was to compare the proportion of women who achieved successful vaginal delivery after induction. The study also assessed the time interval from first treatment to vaginal delivery among successful cases. Additional maternal and neonatal outcomes included peripartum hemorrhage, premature rupture of membranes, and admission of the newborn to the neonatal intensive care unit within 48 hours after delivery.
