剖宫产术后再次妊娠时限与子宫下段肌层厚度的关系研究 　　【摘要】目的：探讨剖宫产术后再次妊娠时限与子宫下段肌层厚度的关系研究。方法：选择我院2012年1月至2014年1月收治的80例剖宫产术后再次妊娠患者为研究对象，通过剖宫产后至再次妊娠时限的不同分为A组19例（间隔时限≤3年），B组26例（间隔时限3～6年），C组20例（间隔时限6～9年），D组15例（间隔时限9年），分析比较各组患者子宫下段肌层厚度值和阴道试产成功率，及不同方法对子宫下段肌层厚度的测量。结果：通过对各组患者子宫下段肌层厚度的检测发现，四组患者的子宫下段肌层厚度间的差异具有统计学意义（P0.05）。结论：剖宫产术后再次妊娠时限在3年左右的患者子宫下段肌层厚度最佳，适合再次分娩，但是时间越长子宫下段肌层厚度越薄，就会降低阴道试产的成功率 【关键词】剖宫产术后再次妊娠；时限；子宫下段肌层厚度 Relationship between interval of pregnancy after cesarean section and lower uterine segment thicknessWEN Ling1， HOU Shunyu2. 1.

Methods： 80 pregnant women after cesarean section in our hospital from January 2012 to January 2014 were enrolled， and by the interval from caesarean section to subsequent pregnancy were divided into group A （n=19， interval between ≤3 years）， group B （n=26， interval between 3 ～ 6 years）， group C （n=20， interval between 6 to 9 years） and group D （n=15， interval duration 9 years）. The lower uterine segment thickness and the success rate of vaginal trial delivery and different measurement methods of lower uterine segment thickness were compared. Results： Differences in lower uterine segment thickness and the success rate of vaginal trial delivery among the four groups were statistically significant （P 0.05）. Conclusion： Women get pregnant 3 years after cesarean section have the most suitable lower uterine segment thickness， but the longer the interval is， the thinner lower uterine segment thickness becomes， which will reduce the success rate of vaginal trial delivery. 【Key words】Pregnancy after cesarean section； Interval； Lower uterine segment thickness 【中图分类号】R714.2【文献标志码】A 剖宫产术是产科领域中的重要手术，
