Perinatal mortality and morbidity are increased in prolonged pregnancy. The application of antepartum fetal testing and intrapartum fetal heart rate monitoring in prolonged pregnancy has decreased the perinatal mortality and morbidity, but the perinatal morbidity remains higher in patients delivering after term than in those delivering at term. Recent evidence suggests that delivery at an earlier gestational age using modern labor-induction techniques may prevent the increase in perinatal mortality and morbidity associated with prolonged pregnancy without increasing the incidence of prolonged labor and cesarean delivery.
过期妊娠时围产期死亡率和发病率会增加。在过期妊娠中应用产前胎儿检测和产时胎儿心率监测已降低了围产期死亡率和发病率，但足月后分娩的患者围产期发病率仍高于足月分娩者。最近的证据表明，使用现代引产技术在较早孕周分娩可预防与过期妊娠相关的围产期死亡率和发病率增加，而不会增加产程延长和剖宫产的发生率。
