Maternal mortality in an urban hospital. A fifteen-year survey.

A 15-year survey of maternal mortality in a large urban hospital revealed an overall rate of 2.95 deaths per 10,000 pregnancies (3.44 per 10,000 live births), representing 31 maternal deaths among approximately 105,000 deliveries and spontaneous and therapeutic abortions. This rate showed marked improvement during the 15-year period, ie, 6.56 per 10,000 pregnancies for the first 5 years as compared to only 1.37 per 10,000 pregnancies for the last 10 years. In contrast to the classic triad of causes of maternal death--toxemia, hemorrhage, and spesis--the principal cause of death in this series was amniotic fluid embolism. Other aspects of the causes of death and of the findings are discussed. Among the 32 fetuses, total fetal wastage was 63%, with a neonatal mortality of 8% and a fetal mortality of 46%.
