The incidence of asphyxia and mortality has been evaluated retrospectively in 716 breech newborns who were vaginally or by elective caesarean section delivered. In the group of 171 preterm infants the rate of asphyxia and mortality has been more elevated in the newborns vaginally delivered; in the group of 545 term infants has not been any difference between those who were delivered vaginally or by caesarean section. About the 50% of the term infants and only the 8% of the preterm infants were delivered by caesarean section. Consequently, we can deduce that the elective caesarean section would be used also in infants of GA less than or equal to 36 weeks.
我们对716例经阴道分娩或择期剖宫产的臀位新生儿的窒息发生率和死亡率进行了回顾性评估。在171例早产儿组中，经阴道分娩的新生儿窒息率和死亡率更高；在545例足月儿组中，经阴道分娩和剖宫产的新生儿之间没有差异。约50%的足月儿和仅8%的早产儿通过剖宫产分娩。因此，我们可以推断，对于孕周小于或等于36周的婴儿也会采用择期剖宫产。
