Objective To investigate the effect and safety of modified B-Lynch suture combined with uterine artery ligation in treatment of postoperative refractory postpartum hemorrhage ( PPH) and find new methods for conservative treatment of intractable PPH .Methods A retrospectively analysis was conducted on the clinical data of 61 cases of cesarean section with intractable PPH from January 2006 to December 2012 in department of gynecology and obstetrics of Ankang Maternal and Child Health Hospital .According to different methods , these cases were divided into two groups , study group using modified B-Lynch suture combined with uterine artery ligation treatment ( 28 cases), and control group using traditional methods of treatment (33 cases).Results The intraoperative bleeding volume , bleeding volume 24 hours after operation , average blood transfusion volume and puerperal disease rate of the study group were obviously superior to the control group, and the differences were statistically significant (χ2 value was -2.466, -5.609, -4.811 and 4.573,respectively, all P<0.05).Conclusion The modified B-Lynch suture combined with uterine artery ligation is a simple medical treatment with obvious curative effect for refractory PPH .No special medical equipments are needed .It is suitable for popularization and application in grassroots hospitals.%目的：探讨改良B-Lynch缝合联合子宫动脉上行支结扎术治疗难治性产后出血（难治性PPH）的效果及安全性，为保守治疗难治性PPH寻找新的方法。方法将安康市妇幼保健院妇产科2006年1月至2012年12月61例剖宫产术中发生难治性PPH患者的临床资料进行回顾性分析，根据治疗方法不同分为两组，应用改良B-Lynch缝合联合子宫动脉上行支结扎术治疗的为研究组（28例），采用传统方法治疗者为对照组（33例）。结果研究组在术中、术后24小时出血量、平均输血情况、产褥病率等方面均优于传统方法，差异有统计学意义（χ2值分别为-2．466、-5．609、-4．811、4．573，均P＜0．05）。结论改良B-Lynch缝合联合子宫动脉上行支结扎术是治疗剖宫产术中发生难治性PPH的一种疗效显著、方法简单、不需特殊医疗器械、适宜在基层医院推广应用的临床技术。
