瘢痕子宫再次剖宫产术后出血因素临床分析

摘要

目的：探讨瘢痕子宫再次剖宫产术后出血的临床因素，并拟定预防对策。方法：收治瘢痕子宫行再次剖宫产术的产妇864例，其中发生产后出血39例，按照出血原因分为胎盘因素组8例，宫缩乏力组21例，切口裂开组9例。结果：比较剖宫术中出血量，上述3组组间差异有统计学意义(P＜0.05)。针对宫缩乏力组和切开裂开组，比较其术中出血量，组间差异有统计学意义(P＜0.05)。结论：瘢痕子宫再次剖宫产大多数是因为胎盘因素导致的产后出血，也是产后出血的重要危险因素，因此，需要及时给予处理预防。%Objective:To explore the clinical factors of postoperative bleeding after cesarean section in scar uterus,and to develop preventive measures.Methods:864 pregnant women with cesarean section in scar uterus were selected,and 39 cases had postoperative bleeding.According to the causes of hemorrhage,they were divided into the placenta factor group with 8 cases, uterine inertia group with 21 cases,dehiscence of incision group with 9 cases.Results:We compared the amount of bleeding in cesarean section,and the difference among the 3 groups was significant(P<0.05).For uterine inertia group and dehiscence of incision group,we compared the amount of bleeding in operation,the difference was significant(P<0.05).Conclusion:Most postpartum hemorrhage of cesarean section in scar uterus were caused by placental factors.It was also an important risk factor for postpartum hemorrhage,therefore it need to be treated and prevented in time.
