目的:探讨影响高龄孕妇剖宫产发生产后出血的危险因素。方法:选择40例剖宫产产后出血的高龄孕妇为研究组,同期行剖宫产产后非出血的高龄孕妇460例为对照组。对可能造成术后出血的因素进行单因素分析,对于影响显著的因素进行多因素Logistic回归分析。结果:研究组中的妊娠高血压史、流产史、宫缩乏力、巨大儿及前置胎盘的发生率明显高于对照组(P<0.05)。经多因素Logistic回归分析,高龄孕妇剖宫产发生产后出血的高危因素依次为宫缩乏力、前置胎盘、妊娠高血压史、巨大儿、流产史。结论:影响高龄孕妇剖宫产发生产后出血的主要因素为宫缩乏力、前置胎盘、妊娠高血压史,为临床有效预防高龄孕妇剖宫产产后出血提供了理论依据。
Objective: To investigate the risk factors of postpartum hemorrhage affecting cesarean section in elderly pregnant women. Methods: Forty pregnant women with cesarean section postpartum hemorrhage were selected as the study group. 460 pregnant women with non-hemorrhage after cesarean section were selected as the control group. Univariate analysis of the factors that may cause postoperative bleeding and multivariate logistic regression analysis were used to analyze the influential factors. Results: The incidence of pregnancy-induced hypertension, abortion history, uterine atony, macrosomia and placenta previa in study group were significantly higher than those in control group (P <0.05). Logistic regression analysis showed that the risk factors for postpartum hemorrhage in cesarean section were as follows: uterine atony, placenta previa, pregnancy-induced hypertension, macrosomia and abortion history. Conclusion: The main factors influencing postpartum hemorrhage in cesarean section of pregnant women are the history of uterine atony, placenta previa and pregnancy-induced hypertension, which provides a theoretical basis for effectively preventing postpartum cesarean section bleeding in elderly pregnant women.
