[Induction of labour: benefits and risks]. / Déclenchement de l'accouchement: le pour et le contre.

A large proportion of pregnant women have induction of labour at or near term. Few randomized trials have evaluated the various indications to induce labour. In some cases, induction is highly recommended to avoid a life-threatening complication for the fetus or the mother. In other cases, the indication is controversial. We review the evidence for a benefit in case of post-term, premature rupture of membranes, maternal hypertensive disorders and suspicion of fetal macrosomia. In case of maternal diabetes or intrauterine growth impairment the need for induction of labour must probably be discussed according to the clinical features. In the above mentioned indications, it does not seem that the risk of caesarean section is increased.
