On the basis of a series of 600 deliveries between January 1 and May 1 1993, the authors analyze cases of unrecognized delivery-related hemorrhage. Hemorrhage of this type, defined retrospectively on the basis of a difference of at least 3g/100 ml in hemoglobin levels at the time of admission to the labor ward and on the 2nd day post-partum, were found in 3.83% of deliveries and were responsible for 51.11% of falls in hemoglobin of 3g/100 ml or more. Primiparity, induced labor (oxytocics), episiotomy, forceps extractions and cesarean section are their etiologic factors. Particular care should be taken in the presence of any of these factors and induced labor may be useful in the prophylaxis of these unrecognized hemorrhages.
基于1993年1月1日至5月1日期间的600例分娩病例，作者分析了未被识别的与分娩相关的出血情况。这种类型的出血是根据入院时和产后第2天血红蛋白水平至少相差3g/100ml进行回顾性定义的，在3.83%的分娩病例中被发现，并且占血红蛋白下降3g/100ml及以上病例的51.11%。初产、引产（催产素）、会阴切开术、产钳助产和剖宫产是其病因。存在这些因素中的任何一种时都应格外小心，引产可能有助于预防这些未被识别的出血情况。
