The effect of the obstetrician's choice for delivery route on infant outcomes was studied in 17,260 mothers in labor, with the fetus alive at the onset of labor, in vertex presentation, and without major congenital anomalies. At birth weight categories, stratified by 500 gm increments, there was no improvement in intrapartum and neonatal mortality or in neonatal morbidity associated with the cesarean birth route. The major dependent variables important in neonatal outcome were birth weight and neonatal maturity. The association between cesarean section delivery and outcome in vertex presentations is limited. This information documents the need for prospective randomized and controlled studies with respect to proposed changes in birth route for the very low-birth weight fetus.
在17260名临产母亲中研究了产科医生选择的分娩方式对婴儿结局的影响，这些母亲临产后胎儿存活，为头先露，且无重大先天性异常。按出生体重类别分层，以500克为增量，剖宫产分娩途径在产时和新生儿死亡率或新生儿发病率方面并无改善。对新生儿结局重要的主要因变量是出生体重和新生儿成熟度。剖宫产分娩与头先露结局之间的关联有限。该信息证明有必要针对极低出生体重胎儿拟议的分娩途径变化进行前瞻性随机对照研究。
