During the six years 1970--1975, 62,266 deliveries occurred at Women's Hospital, Los Angeles Country--University of Southern California Medical Center. Of these patients, 18,106 (29 per cent) were monitored, with an incidence of 18 per cent in 1970 which rose to 35 per cent in 1975. The patients were divided into monitored and unmonitored groups for comparison of cesarean section rates and various aspects of perinatal mortality. The overall cesarean section rate was 9.6 per cent with 2,830 cesareans performed in monitored patients (16 per cent) and 3,124 in those unmonitored, a 7 per cent incidence including repeat cesarean. The cesarean rate remained remarkably stable over the 6-year study period even though the monitoring incidence nearly doubled. From 1970 to 1975, the intrapartum death rate fell progressively in contrast to the incidence of antepartum fetal deaths, which remained unchanged. Overall, 50 per cent survival rate was achieved in the birth weight range of 1,200 grams. A particular group of perinatal patients who apparently benefited from intrapartum monitoring were those liveborns with birth weights of 1,500 grams or less. Over the study period, the neonatal mortality in monitored patients declined, whereas mortality in the neonates which were not monitored during labor remained high.
在1970年至1975年的六年期间，洛杉矶县南加州大学医学中心妇女医院共分娩62266例。在这些患者中，18106例（29%）接受了监测，监测发生率在1970年为18%，到1975年升至35%。将患者分为监测组和非监测组，以比较剖宫产率和围产期死亡率的各个方面。总体剖宫产率为9.6%，监测患者中有2830例进行了剖宫产（16%），非监测患者中有3124例，包括再次剖宫产的发生率为7%。尽管监测发生率几乎翻倍，但在为期6年的研究期间，剖宫产率仍保持显著稳定。从1970年到1975年，与产前胎儿死亡发生率保持不变形成对比的是，产时死亡率逐渐下降。总体而言，出生体重在1200克范围内的存活率为50%。一组明显从产时监测中受益的围产期患者是出生体重在1500克及以下的活产儿。在研究期间，监测患者的新生儿死亡率下降，而分娩期间未监测的新生儿死亡率仍然很高。
