Induction of labour in twin pregnancy.

Labour was induced in 32 high-risk twin pregnancies and the outcome compared with that in 32 twin pregnancies ending in spontaneous labour. No significant differences were found between the groups in terms of duration of labour and mode of delivery, and there were no failures of induction. Perinatal outcome was compared by measuring Apgar scores and cord arterial blood pH levels. There were no significant differences between the groups. Problems of management of labour are discussed and it is considered that induction of labour is an acceptable form of management of high-risk twin pregnancy.
