目的:探讨胎盘早剥发生的相关危险因素及预防策略,为防治胎盘早剥供依据。方法:采用回顾性病例对照研究,选择98例胎盘早剥孕妇作为病例组,随机抽取同期产检的98例正常孕妇作为对照组,采用单因素和多因素Logistic回归分析法来筛选胎盘早剥发生的相关危险因素。结果:单因素分析显示高龄孕妇、妊高征、无规律产检、吸烟史、流产史、药物滥用史、脐带异常、羊水异常、胎膜早破、机械因素、疤痕子宫等因素均为胎盘早剥发生的危险因素;而多因素结果显示高龄孕妇(OR=2.261)、妊高征(OR=8.207)、无规律产检(OR=4.216)、羊水异常(OR=3.016)、胎膜早破(OR=2.389)和机械因素(OR=6.334)为胎盘早剥的独立危险因素。结论:胎盘早剥发生的危险因素较多,应针对这些危险因素采取有效的干预措施,减少其对母婴妊娠结局的影响。
Objective: To explore the risk factors associated with placental abruption and prevention strategies for the prevention and treatment of placental abruption based on. Methods: A retrospective case-control study was conducted in 98 cases of placental abruption pregnant women as the case group, 98 normal pregnant women were randomly selected as the control group, single factor and multivariate Logistic regression analysis to screen for placental abruption Related risk factors. Results: Univariate analysis showed that placental abruption was the most common cause of pregnancy in pregnant women, pregnancy-induced hypertension, irregular pregnancy, smoking history, miscarriage history, history of drug abuse, umbilical cord abnormality, amniotic fluid abnormality, premature rupture of membranes, mechanical factors, (OR = 2.261), pregnancy-induced hypertension (OR = 8.207), irregular pregnancy test (OR = 4.216), amniotic fluid abnormality (OR = 3.016), premature rupture of membranes = 2.389) and mechanical factors (OR = 6.334) were independent risk factors for placental abruption. Conclusion: There are many risk factors for placental abruption, and effective interventions should be taken according to these risk factors to reduce their impact on pregnancy outcome.
