Brief summary

This is a prospective randomised, double blind, placebo controlled trial comparing vaginal prostaglandins E2 gel with an oral synthetic prostaglandin E2 analogue (misoprostol) in the induction of labour at term. Both agents are thought to be equally effective in inducing labour. The main outcomes assessed in this study will be the rate of caesarean section, the number of women who remain undelivered after 24 hours, and uterine hyperstimulation with associated changes in the fetal heart rate. Women, caregivers and outcome assessors (MILO trial) are blinded. For the timing of induction component, it is not possible for women or caregivers to be blinded.

Interventions

Misoprostol group: oral misoprostol in solution (1mg/ml) 20 mls repeated two hourly to a maxmimum of 12 doses plus placebo vaginal gel treatment. Vaginal prostaglandin group: oral placebo (25mg pyradoxive) following dosing regimen described above plus prostaglandin vaginal gel
