A review of 4320 consecutive term deliveries identified 258 women (6%) delivered at a gestational age of 42 weeks or longer. The group accounted for 30% of all cesarean sections for fetal distress, 30% of all infants with a low five-minute Apgar score, 40% of neonatal intensive care admissions, 60% of neonatal deaths, and 30% of all stillbirths. Nonstress tests were performed on 228 women with a postmature pregnancy. Results were defined as normal (score 7 to 10) in 83.4%, inconclusive (score 5 to 6) in 12.2%, and abnormal (score 1 to 4) in 4.4% of these cases. Monitored patients did significantly better than patients in the nonmonitored group, and so did those with normal nonstress test scores when compared with the abnormal scores. Whereas perinatal mortality in the monitored group was similar to that in the nonpostmature population, the perinatal morbidity was significantly higher.
对4320例连续足月分娩病例的回顾发现，有258名妇女（6%）在孕42周或更长孕周分娩。该组占因胎儿窘迫而行剖宫产总数的30%，占5分钟阿氏评分低的所有婴儿的30%，占新生儿重症监护病房收治人数的40%，占新生儿死亡人数的60%，占所有死产的30%。对228例过期妊娠妇女进行了无应激试验。结果显示，在这些病例中，83.4%为正常（评分7至10），12.2%为不确定（评分5至6），4.4%为异常（评分1至4）。接受监测的患者比未监测组患者情况明显更好，无应激试验评分正常的患者与异常评分患者相比也是如此。虽然监测组的围产期死亡率与未过期妊娠人群相似，但其围产期发病率明显更高。
