Abstract
Background. Induction of labor in women with late fetal death is often difficult in settings with scarce resources. The purpose of this study was to assess the value of vaginal misoprostol for induction of labor in women with such fetal death. Methods. In Maputo 156 women with late fetal death were allotted in a non-randomised way to either vaginal misoprostol or intravenous infusion of oxytocin. Treatment outcomes were compared as to cost-effectiveness and safety. In the misoprostol group none received more than 800 µg. Oxytocin infusion followed an established routine. Statistical analyses were performed by EPI Info software. Results. In cases with Bishop's score p=0.4). Women with intact membranes had an induction-to-delivery interval of 13.8 hours in the misoprostol group and 26.9 hours in the oxytocin group (p=0.002). The corresponding values in women with ruptured membranes were 7.8 and 10.5 hours, respectively (p=0.6). Successful induction was achieved in 81% of misoprostol-treated women at a dose of 100 pg or less. Conclusions. Vaginal misoprostol is a safe, low-cost drug particularly suitable in women of high average parity having late, fetal death.
