The greatest danger in a prolonged pregnancy is to the infant. Postmaturity is second only to prematurity as a cause of fetal and neonatal mortality. This article delineates predisposing maternal risk factors, various antepartum screening tests, symptoms of the infant postmaturity syndrome, and the long-term infant effects of a prolonged pregnancy as reported in recent literature. Various types of management plans for prolonged pregnancies are presented in the literature. They range from automatic induction to a “wait and see” attitude. Through appropriate dating of the pregnancy and judicious use of antepartum screening tests, one can expect good outcomes from a prolonged pregnancy without the use of automatic induction.
