Don’t proceed to induction of labour before 39 weeks of gestation if appropriate maternal or fetal indications are lacking.
Induction of labour implies the medicalization of a physiological event and can cause some adverse effects as prolonged latent phase of labour and increased blood loss. Therefore induction is indicated only when the pregnancy continuation may involve a real danger to the fetus or to the mother. The term induction of labour does not increase the risk of cesarean section.
In the prolonged pregnancies induction must not be offered before 41+3 weeks of gestation but within 42+0 weeks or in case of term pregnancy with isolated oligohydramnios if AFI (Amniotic Fluid Index) is less than 50 mm or maximum pocket less than 20 mm after oral hydration with 2000 ml.
