Vaginal misoprostol induction of labour: a Nigerian hospital experience

We reviewed our experience with vaginal misoprostol induction of labour in 339 consecutive women with a live fetus and intact fetal membrane using 100 mcg 12-hourly until labour was established. The labours were monitored using the WHO partograph protocol.

The induction delivery interval among the women who had successful induction ranged from 3 hours 42 minutes to 26 hours 15 minutes with a mean of 9 hours 23 minutes (SD 2 hours 41 minutes). Most (73.6%) of these patients delivered within 12 hours of starting induction, the majority (95.3%) requiring only 100 mcg to go into established labour. Complications recorded in this series include fetal distress in 32 (9.4%), postpartum haemorrhage in 23 (6.8%), hyperstimulation in six (1.8%), uterine rupt...
