剖宫产产后出血的危险因素分析

目的探究剖宫产产后出血的危险因素。方法对本院508例行剖宫产的患者的临床资料进行回顾,分析可能与剖宫产产后出血相关的危险因素。结果 508例剖宫产分娩的产妇中发生产后出血的有45例(8.9%,45/508)。不同病理特征分组的组间分析结果显示:高龄、多胎妊娠、多次流产史、妊娠期高血压、胎盘早剥、前置胎盘和子宫切口撕裂均是产妇行剖宫术分娩后产后出血的重要危险因素。单因素分析和多因素回归分析结果显示:前置胎盘、多胎妊娠、子宫切口撕裂和胎盘早剥是剖宫产产后出血的独立危险因素(P0.05)。结论前置胎盘、多胎妊娠、子宫切口撕裂和胎盘早剥是剖宫产产后出血的独立危险因素。

Anaylsis of risk factor of hemorrhage after cesarean section

Objective： To explore risk factors of hemorrhage after cesarean section. Methods. A total of 508 patients with cesarean section admitted in our hospital .were selected to analyze the risk factors of hemorrhage after cesarean section. Results. Among the patients,there were 45 patients with postpartum hemorrhage after the cesarean section（8.9%, 45/508）. The analysis results in different pathological groups showed that high age, multifetation,repeated abortion, gestational hypertension, placental abruption, placenta previa and uterine incision laceration were the significant risk factors of hemorrhage after cesarean section. Single factor analysis and multi-factor regression analysis showed that placenta previa, multifetation, uterine incision laceration and placental abruption were the independent risk factors of hemorrhage after Cesarean section. Conclusions： Placenta previa, muitifetation, uterine incision laceration and the placental： abruption Were the independent risk factors of hemorrhage after cesarean section.
