Prolapse of the umbilical cord occurred 69 times in 30112 deliveries. The incidence was higher in abnormal presentations, particularly in compound presentation (11.1%), and in breech presentation (2.9%), especially when these occurred in association with prematurity. Twenty-five (36.2%) of the 69 infants died; 21 of these were dead at the time of diagnosis of cord prolapse, two died in the neonatal period of respiratory distress syndrome, and two died from complications of breech extraction. Reduction in perinatal mortality will be possible only if early diagnosis of cord prolapse can be made by means of vaginal examination or fetal heart monitoring, and the birth trauma associated with difficult vaginal delivery prevented.
在30112例分娩中，脐带脱垂发生了69次。异常胎位时发生率较高，尤其是复合先露（11.1%）和臀先露（2.9%），特别是当这些情况与早产相关时。69例婴儿中有25例（36.2%）死亡；其中21例在诊断脐带脱垂时已死亡，2例在新生儿期死于呼吸窘迫综合征，2例死于臀位牵引的并发症。只有通过阴道检查或胎儿心率监测尽早诊断脐带脱垂，并预防与困难阴道分娩相关的产伤，才能降低围产期死亡率。
