Little is known about the comparative safety of the low transverse versus the low vertical uterine incision for cesarean delivery of singleton infants in breech presentation. To address this question, the short-term maternal and infant complications of 221 breech deliveries by low transverse incision and 195 by low vertical incision were analyzed. The perinatal mortality rate associated with the low transverse incision was significantly lower than that associated with the low vertical incision (41 versus 92 deaths per 1000 births; P less than .05). When standardized for birth weight or gestational age, the difference was no longer statistically significant (P greater than .05). The incidences of an Apgar score of 6 or lower, extension of the uterine incision, a decrease in hematocrit by 6 points or more, blood transfusion, and maternal fever were not significantly different. Since these types of incisions appear to have comparable safety, the possibility of a vaginal delivery with later pregnancies suggests that the low transverse uterine incision is preferable to the low vertical incision.
对于臀位单胎剖宫产时低位横切口与低位纵切口的相对安全性，人们了解甚少。为解决这个问题，分析了221例低位横切口臀位分娩和195例低位纵切口臀位分娩的近期母婴并发症。低位横切口相关的围产期死亡率显著低于低位纵切口相关的围产期死亡率（每1000例出生中有41例死亡对92例死亡；P小于0.05）。按出生体重或孕周进行标准化后，差异不再具有统计学意义（P大于0.05）。阿氏评分6分及以下、子宫切口延长、血细胞比容下降6个百分点或更多、输血和产妇发热的发生率无显著差异。由于这些类型的切口似乎具有相当的安全性，后续妊娠进行阴道分娩的可能性表明，低位横切口比低位纵切口更可取。
