Twelve hundred nineteen maternal deaths occurring from 1957 through 1966 in the State of California have been reviewed by the Maternal Mortality Committee of the California Medical Association and the Bureau of Maternal and Child Welfare of the State of California. In 56 of these deaths the underlying causes were due to disorders of placental separation and placental bed hemostasis. Each of these 56 cases has been analyzed. Profiles of characteristics of patients dying from placenta previa, placenta abruptio, and uterine atony are given. The expected causes of death due to delay in giving adequate amounts of blood and fibrinogen occurred in this series but the most striking results of this study were the findings of (1) a large number of cases of placenta acreta in patients with repeat cesarean sections and (2) the lack of manual exploration of the uterus in many patients dying from uterine atony.
加利福尼亚医学协会孕产妇死亡率委员会和加利福尼亚州母婴福利局对1957年至1966年期间发生在加利福尼亚州的1219例孕产妇死亡病例进行了审查。在这些死亡病例中，有56例的根本原因是胎盘剥离和胎盘床止血障碍。对这56例病例逐一进行了分析。给出了因前置胎盘、胎盘早剥和子宫收缩乏力死亡患者的特征概况。本系列病例中出现了因未能及时输注足够量血液和纤维蛋白原而导致的预期死亡原因，但这项研究最显著的结果是发现：（1）剖宫产史患者中大量胎盘植入病例；（2）许多因子宫收缩乏力死亡的患者未进行子宫手探。
