A simpler approach to labor induction using lipid-based prostaglandin E2 vaginal suppository.
The outcome of labor induced by use of a glyceride-based vaginal suppository of prostaglandin E2 (PGE2) inserted 3 hours before amniotomy, when the cervix is favorable, has been assessed. Using 5 mg PGE2 for primigravidas and 2.5 mg for multigravidas, 63% of the former and 81% of the latter established labor and were delivered of their infants without oxytocin augmentation, allowing ambulation during early labor. No maternal complications were detected as a result of the PGE2 treatment. Compared with patients undergoing conventional induction by amniotomy and immediate oxytocin titration there was no difference in the duration of labor, with a few patients establishing labor and giving birth quickly with both induction methods. Fetal distress was less common following PGE2 treatment than following conventional induction, with three patients in each group requiring delivery by cesarean section. Cephalopelvis disproportion in the second stage of labor requiring cesarean section to deliver occurred more frequently in the prostaglandin-treated group, possibly as a result of reduced upper segment contractility in the first stage of labor with subsequent poor fetal head molding. Epidural analgesia and postpartum hemorrhge were both reduced following PGE2-induced labor.
