This study was undertaken to determine the effect of choice of birth route on infant outcome in fetal breech presentation. The study group excluded infants who were footling breeches and infants with major congenital anomalies. The mothers were in labor with the fetal heartbeat present at entry into the labor room. Outcome variables were intrapartum and neonatal deaths and neonatal neurological morbidity. Delivery route was not significantly associated with neonatal death in the 500 to 999 gm (p = 0.43) and 1,000 to 2,499 gm (p = 0.43) categories. Over 2,500 gm, there were no neonatal deaths. In similar manner, delivery route was not significantly associated with neonatal neurological morbidity. In both neonatal death and morbidity, birth weight and modified Dubowitz score explained the largest proportion of the variance for outcome in breech presentation.
本研究旨在确定臀位胎儿分娩途径的选择对婴儿结局的影响。研究组排除了足先露婴儿和患有重大先天性异常的婴儿。母亲们进入产房时胎儿心跳存在且处于分娩状态。结局变量为产时和新生儿死亡以及新生儿神经疾病发生率。在体重500至999克（p = 0.43）和1000至2499克（p = 0.43）的类别中，分娩途径与新生儿死亡无显著相关性。超过2500克时，无新生儿死亡。同样，分娩途径与新生儿神经疾病发生率无显著相关性。在新生儿死亡和发病率方面，出生体重和改良的杜波维茨评分在臀位分娩结局的方差中所占比例最大。
