title: Induction of labor. A double-blind randomized controlled study of prostaglandin E2 vaginal suppositories compared with intranasal oxytocin and with sequential treatment.
abstract: In a double-blind randomized controlled study of 300 women, 150 primiparas and 150 multiparas, induction of labor by means of vaginal suppositories containing 3 mg prostaglandin E2 (PGE2) was compared with the conventional method of intranasal oxytocin and with a combined method of 3 mg PGE2 vaginal suppositories alternating with intranasal oxytocin. In the PGE2 group the intensity of delivery was significantly greater than in the oxytocin group, among both primiparas and multiparas and among the patients with ripe and unripe cervix. The efficiency of the combined treatment could no be evaluated because of the high intensity of delivery during the first 24 hours. There were no maternal side effects, and no significant difference in the frequencies of failed induction and cesarean section.
