“Induction of labour in medically uncomplicated nulliparous women at term carries a more than doubling of risk of emergency CS [caesarean section], compared with spontaneous labour, with no impact on perinatal mortality.
All methods of induction and augmentation of labour were associated with an increase in the rate of CS.
Women included in this study had no apparent medical indication for induction of labour or any complication of pregnancy, so the increase in CS was not due to identifiable underlying risk factors.
These results suggest that, in the absence of direction from well-designed, contemporary RCTs, minimising unindicated inductions before 41 weeks’ gestation has the potential to reduce the rate of CS.”
