| ［摘要］ 目的 探讨剖宫产产后出血的相关因素，为其防治提供参考。方法 选择剖宫产产后出血产妇118例（出血组）,并与同期年龄相仿、无剖宫产后出血的产妇118例（对照组）对照。收集两组有关的临床资料（包括年龄、职业、孕产次、孕周等),通过χ2检验比较两组暴露因素的构成差异，采用多因素Logistic回归分析筛选剖宫产产后出血的高风险独立相关因素。结果 单因素分析显示，出血组的脑力劳动、孕周<37周、胎盘异常（胎盘粘连或植入）、择期剖宫产、宫缩乏力、子宫裂伤、妊娠期高血压疾病、新生儿体重≥4.0 kg的构成比高于对照组（P=0.001～0.045）。多因素Logistic回归分析显示，宫缩乏力（OR=5.367；95%CI:2.451～11.755)和子宫裂伤（OR=5.778；95%CI:1.963～17.009）是剖宫产产后出血的高风险独立相关因素。结论 宫缩乏力和子宫裂伤是剖宫产产后出血的高风险因素，应加强防护。 |

| ［Abstract］ Objective To explore the related factors of postpartum hemorrhage in cesarean section in order to provide reference for prevention and treatment of postpartum hemorrhage in cesarean section.Methods By Chi-squarce test,the difference in the constituent of exposure factors were tested between 118 parturient women with postpartum hemorrhage in cesarean section(hemorrhage group) and 118 parturient women without postpartum hemorrhage in cesarean section(control group),with similar age in the same time. And then the Multivariat logistic regression analysis was performed to screen the independent high risk factors for postpartum hemorrhage.Results Univariate analysis showed that in hemorrhage group,the constituent ratio in mental labour, gestational age <37 weeks, abnormal placenta(placenta adhesion or implantation), elective cesarean delivery, uterine inertia, uterine laceration, gestational hypertension disease, neonatal weight ≥4.0 kg were higher compared with the control group (P=0.001～0.045). Multivariate logistic regression analysis revealed that uterine inertia(OR=5.367; 95%CI: 5.367～11.755) and uterine laceration(OR=5.778; 95%CI:1.963～17.009) were the high-risk independent factors for postpartum hemorrhage.Conclusion Uterine inertia and uterine laceration are the related high risk factors for postpartum hemorrhage, and should strengthen the prevention of them. |
