目的:探讨不同产程剖宫产术与子宫切口撕裂的关系。方法:对2005年1月～2009年12月期间在山西省中阳县人民医院行剖宫产分娩的652例产妇的临床资料进行回顾性分析。结果:652例孕妇行剖宫产,术中发生子宫切口撕裂26例,撕裂率为3.99%;其中初产妇14例,经产妇12例,孕38～42周16例,>42周10例。未进入产程和进入产程的产妇子宫切口撕裂发生率分别为1.27%和6.55%,两组子宫切口撕裂发生率差异有统计学意义(P=0.001);进入产程的三组患者子宫切口撕裂发生率差异有显著的统计学意义(P<0.01),撕裂伤的具体情况差异也有统计学意义(P<0.05);三组之间的出血情况差异没有统计学意义(P>0.05)。结论:剖宫产术中子宫切口撕裂与产程有关,第二产程撕裂发生率显著高于第一产程。宫口开得越大,撕裂发生率越高。 Objective: To investigate the relationship between cesarean section and uterine incision laceration in different stages of labor. Methods: The clinical data of 652 pregnant women delivered by cesarean section in Zhongyang County People’s Hospital of Shanxi Province from January 2005 to December 2009 were analyzed retrospectively. Results: A total of 652 pregnant women underwent cesarean section with 26 cases of uterine incision tear and tear rate of 3.99%. Among them, 14 cases were primipara, 12 cases were maternal, 38 cases were 42 weeks pregnant, 16 cases were week 42, example. The incidence rates of uterine incision without labor and entering the labor process were 1.27% and 6.55%, respectively (P = 0.001). The incidence of torn uterine incision in the two groups was statistically significant (P <0.01). There were also significant differences in the specific conditions of laceration (P <0.05). There was no significant difference in bleeding between the three groups (P> 0.05) . Conclusion: Cesarean section in the uterine incision tear and labor process, the second stage of labor tear was significantly higher than the incidence of the first stage of labor. The greater the cervix open, the higher the incidence of tearing.
