目的探讨改良 B-Lynch 缝合术在预防剖宫产术中宫缩乏力性子宫出血的疗效。方法选择2010年9月至2011年9月具有产后出血高危因素、并有出血倾向的产妇作为实验组，对照组为2009年9月至2010年9月具有上述情况的产妇。实验组行改良 B-Lynch 缝合术，对照组则常规给予药物治疗，术后或配合使用宫颈钳钳夹宫颈。结果实验组30例产妇均成功，产后出血发生率、产后出血量，血色素下降程度均低于对照组，差异有统计学意义。而子宫缩复情况，月经复潮、子宫形态均正常。结论改良 B-Lynch 缝合术式简单安全，止血效果好，为预防剖宫产术中宫缩乏力性子宫出血的首选而有效的方法，可在各级医院，特别是基层推广施行。% Objective To investigate the efficacy of the modified B-Lynch suture in preventing uterine atony bleeding for cesarean section.
