The PGE2 vaginal film: An alternative to conventional induction in multiparae with poor cervical scores

In a study involving 50 multiparous subjects with poor cervical scores (⪕3), induction of labour by conventional amniotomy and oxytocin was compared with preinduction cervical ripening using a single administration of prostaglandin E₂ (850ug) in a new vaginal film formulation. Indications for elective delivery, maternal characteristics and distribution of cervical scores in the two groups were similar. Significant changes in mean cervical score were achieved within 12 hours of film insertion. In this group, 11 subjects (45.8%) established labour within 12 hours and a further 8(33.3%) did so before 24 hours so that only 5 cases required amniotomy and oxytocin. Instrumental delivery was less in this group and none of these subjects required Caesarean section for a failure of induction. No adverse maternal or fetal side effects were observed. Convenience, ease of administration and stability of this new prostaglandin formulation make it a useful alternative to conventional induction of labour in the multiparous patient with a poor cervical score.
