Induction of labour with prostaglandin E2; a prospective audit

To perform a prospective audit of inductions of labour using prostaglandins to assess the protocols for induction in use at that time.

Data on 123 patients was obtained over a six-week period. Information regarding gestation, indication for induction and relevant details of labour and delivery were obtained.

There were three (2.5%) patients with hyperstimulation and six (5%) with failed induction. Nulliparous patients with an unfavourable cervix had an increased caesarean section rate (29%) and a prolonged induction to delivery interval (mean: 27 hours).

The protocols for induction of labour using prostaglandins presently in use appear to be safe although staff need to be well informed about the management of hyperstimulation should it occur. Further audit of indications for induction of labour and of the caesarean section rate is required.
