为探讨臀位婴儿死亡率和分娩方式的关系,作者统计分析了1976～1977两年间分娩的38,186例中臀位胎儿出生体重在1,000g 以上的1,593例,经计算机贮存的资料认为:臀先露阴道分娩和剖腹产的新生儿死亡率(尽管数字很少),二者无统计学差异(P>0.3)。胎儿围产期死亡依统一标准分为产前死亡(即胎儿死在产前或胎心音在分娩开始前消失)、产时死亡(即胎心音在分娩期或临产前可听到但出生婴儿为死产者)及新生儿死亡。本文将新生儿出生体重>1,000g 者分为1,000～1,499g、1,500～1,999g,2,000～2,499g 和>2,500g 四组,
In order to explore the relationship between breech infant mortality and mode of delivery, the authors statistically analyzed the data of 1,593 cases of 38,186 midrib-birth fetuses weighing more than 1,000g who were born between 1976 and 1977. The data stored on computer showed that: There was no significant difference (P> 0.3) in neonatal mortality from vaginal delivery and caesarean section, albeit from a small number. Fetal perinatal death by uniform standard is divided into prenatal death (that is, fetal death in prenatal or fetal heart sound disappeared before delivery), during labor died (ie, fetal heart sound during childbirth or prenatal audible but was born Infants are stillbirths) and neonatal deaths. In this paper, newborn birth weight> 1,000g were divided into four groups of 1,000 ~ 1,499g, 1,500 ~ 1,999g, 2,000 ~ 2,499g and> 2,500g,
