Inducing labor or initiating the pain at 39 weeks of gestation in healthy pregnant women can reduce the risk of cesarean surgery.

‘Induction of labor at 39 weeks of gestation among healthy, first-time mothers reduces the rate of cesarean birth as compared to expectant management among the same population.’






In a study with more than 6,100 pregnant women across the country, researchers randomly assigned half of the women to an expectant management group (waiting for labor to begin on its own and intervening only if problems occur) and the other half to a group that would undergo an elective induction (inducing labor without a medical reason) at 39 weeks of gestation.
Results include:
- Lower rates of cesarean birth among the elective induction group (19%) as compared to the expectant management group (22%).
- Lower rates of pre-eclampsia and gestational hypertension in the elective induction group (9%) as compared to the expectant management group (14%).
- Lower rates of respiratory support among newborns in the induction group (3%) as compared to the expectant management group (4%).
SMFM’s current guidelines do not recommend routine induction of labor for low-risk pregnant women at 39 weeks of gestation. "SMFM will wait to evaluate the peer-reviewed publication of the ARRIVE Trial before providing any guidance or changes to our existing recommendations," said Alfred Abuhamad, MD, the President of SMFM.
