产后出血危险因素临床分析及预防措施研究

Clinical analysis and preventive measure research of postpartum hemorrhage risk factor

目的探讨产后出血的原因及相关危险因素,为防治产后出血提供依据。方法回顾性分析2012年1月-2014年12月在本院进行分娩的502例产妇的临床资料,采用多因素Logistic回归分析法对产后出血的危险因素进行筛选。结果产后出血的发生率为4.18%。多因素Logistic回归分析显示,胎盘残留/植入/粘连、子宫收缩乏力和前置胎盘是产后出血的独立危险因素（P〈0.05）。结论子宫收缩乏力、胎盘残留/植入/粘连、前置胎盘能够增加产妇产后出血的发生概率,应及时采取干预措施以减少产后出血的发生。

Objective To explore the reason and related risk factor for postpartum hemorrhage and to provide basis for preventing postpartum hemorrhage. Methods The clinical data of 502 cases of delivery women in our hospital from January 2012 to December 2014 were analyzed retrospectively,the risk factors of postpartum hemorrhage were selected by using Logistic regression analysis. Results The inncidence rate of postpartum hemorrhage was 4.18%.Multivariate Logistic regression analysis showed that the mode of residual placenta/implantation/adhesion,uterine inertia and pre placenta were related risk factors of postpartum hemorrhage（P〈0.05）. Conclusion Uterine inertia,placenta residue/implantation/adhesion and placenta previa can increase the risk of maternal postpartum hemorrhage,intervention measures should be given timely to reduce the occurrence of postpartum hemorrhage.
