The effect of mode of delivery on the mortality and morbidity of 26- to 32-week neonates was studied. Five hundred six consecutive deliveries at 26 to 32 weeks' gestation were reviewed. The populations were divided into high-risk and low-risk neonates by evaluation of antepartum variables known to increase neonatal risk, ie, abruptio placenta. One hundred ninety-six infants were classified as low risk. In this group, 124 vaginal and 72 cesarean section deliveries were compared using demographic, peripartum, and neonatal variables. Cesarean delivery was associated with highly significant maternal morbidity, including a 30% incidence of vertical uterine incision. No difference in neonatal mortality was shown. Cesarean delivery was associated with lower one-minute Apgar scores and a greater incidence and severity of hyaline membrane disease. No neonatal differences were shown in the incidence of trauma, intraventricular hemorrhage, or seizures. This study does not support cesarean delivery of all tiny neonates.
研究了分娩方式对26至32周龄新生儿死亡率和发病率的影响。回顾了26至32周妊娠的506例连续分娩病例。通过评估已知会增加新生儿风险的产前变量（即胎盘早剥），将人群分为高危和低危新生儿。196名婴儿被归类为低风险。在这一组中，使用人口统计学、围产期和新生儿变量对124例阴道分娩和72例剖宫产进行了比较。剖宫产与产妇的高发病率相关，包括30%的子宫纵切口发生率。未显示新生儿死亡率有差异。剖宫产与较低的1分钟阿氏评分以及透明膜病的更高发病率和严重程度相关。在创伤、脑室内出血或癫痫发作的发生率方面未显示新生儿有差异。本研究不支持对所有极低体重新生儿进行剖宫产。
