This study evaluated the efficacy and safety of "J"-shaped uterine incision for caesarean section for patients diagnosed with placenta previa. A total of 55 consecutive cases of placenta previa treated in Union Hospital were retrospectively analyzed over a period of two years and 10 months. The subjects were divided into two groups with respect to the uterine incision. Twenty-four pregnant women with placenta previa who were indicated for caesarean section underwent the procedure using a new "J"-shaped uterine incision and 31 pregnant women with placenta previa received caesarean section that used the traditional transverse incision. The two groups were compared in terms of operation time, estimated blood loss, infant expulsion time, exhaust time and postoperative recovery. Meanwhile, comparison was also made in neonatal clinical data between the two groups. Compared with the "J"-shaped incision group, the traditional incision group had a lower Apgar scores (P<0.05). However, there existed no statistically significant differences in the overall time of operation and postoperative period of breaking wind (P>0.05). It is concluded that, with caesarean section for placenta previa patients, the "J"-shaped uterine incision significantly decreases intraoperative blood loss and facilitates the fetal delivery.
本研究评估了“J”形子宫切口用于前置胎盘患者剖宫产的有效性和安全性。回顾性分析了协和医院两年零十个月内连续收治的55例前置胎盘病例。根据子宫切口将受试者分为两组。24例有剖宫产指征的前置胎盘孕妇采用新的“J”形子宫切口进行手术，31例前置胎盘孕妇接受传统横切口剖宫产。比较两组的手术时间、估计失血量、胎儿娩出时间、排气时间和术后恢复情况。同时，比较两组新生儿临床数据。与“J”形切口组相比，传统切口组的阿氏评分较低（P<0.05）。然而，手术总时间和术后排气时间差异无统计学意义（P>0.05）。结论是，对于前置胎盘患者剖宫产，“J”形子宫切口可显著减少术中失血并利于胎儿娩出。
