A survey of the management of postterm pregnancy was conducted among the 80 institutions with approved maternal-fetal medicine programs. Seventy-two (90%) completed questionnaires were received. After 42 weeks' gestation, when the cervix is unfavorable for induction, the nonstress test is the most commonly used test to assess fetal well-being (84.7%). In 50% of the institutions, pregnancy is terminated at some point beyond the 42nd week, in spite of an unripe cervix and lack of evidence of fetal compromise. In the other half, intervention does not take place under such conditions. The need for more consistent guidelines for the management of postterm pregnancy is emphasized.
对80家设有经批准的母胎医学项目的机构进行了一项过期妊娠管理情况的调查。共收到72份（90%）完成的调查问卷。妊娠42周后，当宫颈条件不利于引产时，无应激试验是评估胎儿健康状况最常用的检查方法（84.7%）。在50%的机构中，尽管宫颈不成熟且无胎儿窘迫证据，但在妊娠42周之后的某个时间点仍会终止妊娠。在另一半机构中，在这种情况下不会进行干预。强调需要制定更一致的过期妊娠管理指南。
