摘要
目的:探究胎盘粘连对经阴道分娩产后出血的影响,分析产后出血的相关因素。方法:2015年1月~2018年12月于我院经阴道分娩的产妇200例,查阅纳入研究产妇的病历资料,包括产妇年龄、产次、胎次等多项指标,分析胎盘粘连等因素与产后出血的相关性。结果:胎盘粘连产妇的产后出血率显著高于无胎盘粘连者;刮宫次数2次或3次产妇的胎盘粘连发生率显著高于无刮宫者或仅1次刮宫者;随着刮宫次数的增加,胎盘粘连的发生率显著升高;单因素分析结果提示,年龄、孕周、产次、产程延长、妊娠期高血压、前置胎盘、胎盘粘连、子宫收缩乏力与阴道分娩产后出血有关;多因素非条件logistic回归模型,提示妊娠高血压、前置胎盘、胎盘粘连、子宫收缩乏力为经阴道分娩产后出血的独立危险因素。结论:胎盘粘连是经阴道分娩产后出血的独立危险因素之一,其发生情况与刮宫次数成正比。
Objective To explore the effect of placental adhesion on postpartum hemorrhage after vaginal delivery,and to analyze the related factors of postpartum hemorrhage.Methods From January 2015 to December 2018,200 women who were vaginally delivered in our hospital were enrolled in the study of maternal medical records,including maternal age,parity,parity and other indicators.Analysis of the relationship between factors such as placental adhesion and postpartum hemorrhage.Results The postpartum hemorrhage rate of placenta adhesion was significantly higher than that of placenta-free adhesion.The incidence of placental adhesions in 2 or 3 times of women with curettage was significantly higher than those without curettage or only 1 curettage.With the increase of the number of curettage,the incdence of placental adhesion increased significantly.Univariate analysis showed that age,gestational age,parity,prolonged labor,gestational hypertension,placenta previa,placental adhesion,uterine contraction and vaginal delivery were associated with postpartum hemorrhage.Multivariate unconditional logistic regression model indicated that pregnancy-induced hypertension,placenta previa,placental adhesions,and uterine contraction were independent risk factors for postpartum hemorrhage due to vaginal delivery.Conclusion Placental adhesion is one of the independent risk factors for postpartum hemorrhage through vaginal delivery.The incidence is proportional to the number of curettage.
