影响自然分娩产妇发生产后出血相关危险因素分析

Analysis of risk factors related to postpartum hemorrhage in natural labor

目的:分析自然分娩产妇产后出血的危险因素与预防措施。方法:选取2017年12月至2019年5月期间在我院自然分娩的234例产妇的临床资料进行回顾性分析。其中自然分娩无产后出血产妇202例设为对照组,发生产后出血产妇32例设为观察组。对两组资料进行单因素和多因素分析,探究产后出血的相关危险因素。结果:观察组有产道裂伤、胎盘滞留、宫缩乏力、中重度贫血的产妇所占比例显著高于对照组,(P<0.05),(X2=22.215,21.175,8.924,5.033,P<0.05)。多因素分析结果显示,产道裂伤、胎盘滞留、宫缩乏力、中重度贫血是自然分娩产妇发生产后出血的危险因素(OR=5.804,2.862,3.165,3.980,P<0.05)。结论:导致自然分娩产妇产后出血的相关因素相对复杂,需要临床加大产妇产前宣教力度,采取有效的措施预防产后出血的发生。

Objective:To analyze the risk factors and preventive measures of postpartum hemorrhage in natural labor.Methods:A retrospective analysis of clinical data of 234 women who gave birth naturally in our hospital from December 2017 to May 2019.Among them,202 cases of postpartum bleeding without spontaneous delivery were set as the control group,and 32 cases of postpartum bleeding were set as the observation group.Univariate and multivariate analysis was performed on the two groups of data to explore related risk factors for postpartum hemorrhage.Results:The proportion of women with obstetric laceration,placental retention,contraction weakness,and moderate to severe anemia in the observation group was significantly higher than that in the control group(P<0.05),(X2=22.215,21.175,8.924,5.033,P<0.05).Multivariate analysis showed that birth canal laceration,placental retention,contraction weakness,and moderate to severe anemia were risk factors for postpartum hemorrhage in natural delivery(OR=5.804,2.862,3.165,3.980,P<0.05).Conclusion:The related factors that lead to natural postpartum hemorrhage are relatively complicated,and it is necessary to increase the prenatal education of pregnant women clinically and take effective measures to prevent the occurrence of postpartum hemorrhage.
