目的探讨产后出血的危险因素,为产后出血的预防和治疗提供参考。方法对1459例产妇的临床资料进行回顾性分析,对产后出血的相关危险因素进行Logistic回归分析,筛选产后出血的相关危险因素。结果 1459例产妇发生产后出血48例,发生率为3.29%。单因素分析显示年龄、胎次、中重度贫血、前置胎盘、胎盘早剥、子宫收缩乏力、胎盘粘连/植入/残留、软产道裂伤、妊高征、分娩方式、血功能障碍异常等等因素与产后出血有关。多因素Logistic回归分析表明,前置胎盘、胎盘粘连/植入/残留、子宫收缩乏力是产后出血的危险因素。结论前置胎盘、胎盘粘连/植入/残留、子宫收缩乏力是产后出血的危险因素,对这些危险因素加以重点评估和合理控制,可以控制产后出血的发生。
Objective To investigate the risk factors of postpartum hemorrhage and provide reference for the prevention and treatment of postpartum hemorrhage. Methods The clinical data of 1459 maternal women were analyzed retrospectively. The related risk factors of postpartum hemorrhage were analyzed by Logistic regression and the related risk factors of postpartum hemorrhage were screened. Results 1459 maternal postpartum hemorrhage occurred in 48 cases, the incidence was 3.29%. Univariate analysis showed that age, parity, moderate to severe anemia, placenta previa, placental abruption, uterine atony, placenta accreta / implantation / remnant, soft birth canal laceration, PIH, mode of delivery, abnormal blood dysfunction And other factors related to postpartum hemorrhage. Multivariate logistic regression analysis showed that placenta previa, placental adhesion / implantation / residual uterine atony were the risk factors of postpartum hemorrhage. Conclusions The placenta accreta, placenta accreta / implantation, residual uterine atresia and postpartum hemorrhage are the risk factors of postpartum hemorrhage. The critical risk factors of these factors should be evaluated and controlled reasonably to control the postpartum hemorrhage.
