Second-trimester termination with 16,16 dimethyl-PGE1-methyl ester (gemeprost), compared with a regimen that included...

The use of gemeprost (16,16 dimethyl-PGE1-methyl ester) pessaries was compared in an open, randomized single-centre trial with the intra-amniotic injection of PGF2 alpha combined with hypertonic saline, intravenous oxytocin and a hygroscopic cervical dilator (Dilapan) for the termination of pregnancy between 14 and 20 weeks. There was no significant difference in the induction-delivery interval for the two groups. With the exception of an increased incidence of diarrhoea in the gemeprost group, there was no significant difference in other side effects, analgesic requirements or retained placentae. Gemeprost pessaries are an effective alternative to the more invasive methods previously used for the induction of second-trimester termination.
