Abstract
The timely onset of labor and delivery is an important determinant of perinatal outcome. Post-term (prolonged) pregnancy refers to any pregnancy that continues beyond 42 weeks (294 days) of gestation. It complicates 10% of all deliveries and is associated with increased perinatal and neonatal morbidity and mortality, including stillbirth, birth injury, meconium aspiration syndrome, neonatal encephalopathy and infant mortality. Post-term pregnancy also poses significant risk to the mother, including an increased risk of cesarean delivery, severe perineal injury and postpartum hemorrhage. Fortunately, post-term pregnancy can be avoided by earlier induction of labor. The risks of continuing pregnancy beyond the due date, the option of induction of labor and the management of low-risk post-term pregnancies are reviewed.
