The authors have calculated the maternal mortality rates from ectopic pregnancy in the Southeastern United States. Between 1960 and 1975 81 per cent of 207 ectopic deaths occurred in nonwhite women. A more detailed study of 24 deaths from ectopic pregnancy in North Carolina shows that from 1961 to 1976 4.2 per cent of all direct obstetric deaths and 15.9 per cent of deaths from hemorrhage were due to reptured ectopic gestation. The most striking observation was the dramatic reduction in deaths from ectopic pregnancy among nonwhite women. Maternal mortality rates for ectopic pregnancy should properly be based on the conception rate, consisting of live births plus abortions rather than live births alone. Missed diagnosis of ectopic pregnancy as a factor in maternal mortality rate requires more intensive educational efforts directed toward primary-care physicians.
作者们计算了美国东南部宫外孕导致的孕产妇死亡率。1960年至1975年间,207例宫外孕死亡病例中81%发生在非白人女性中。对北卡罗来纳州24例宫外孕死亡病例进行的更详细研究表明,1961年至1976年间,所有直接产科死亡病例中的4.2%以及出血导致死亡病例中的15.9%是由破裂的宫外孕所致。最显著的观察结果是,非白人女性中宫外孕死亡人数大幅减少。宫外孕的孕产妇死亡率应以受孕率为基础来恰当计算,受孕率包括活产数加流产数,而非仅以活产数计算。将宫外孕漏诊作为孕产妇死亡率的一个因素,需要针对基层医疗医生开展更深入的教育工作。
