【摘要】 目的 了解高龄孕妇阴道分娩产后出血的危险因素。方法 选取87例阴道分娩产后出血、100例无产后出血高龄孕妇，Logistic回归分析产后出血危险因素。结果 高龄初产妇、孕周>40周、体质量指数≥25 kg/m~2、新生儿体质量≥3.5 kg、第三产程≥15 min的高龄孕妇，阴道分娩产后出血发生率均较高（P<0.01或0.05）。多因素logistic回归分析结果显示新生儿体质量≥3.5 kg、第三产程≥15 min是产后出血的独立危险因素（P<0.01）。结论 新生儿体质量较大、第三产程较长是高龄孕妇阴道分娩产后出血的危险因素。更多还原

【Abstract】 Objective To analyze the risk factors of postpartum hemorrhage(PH) in elderly pregnant women(EPWs)undergoing vaginal delivery. Methods Clinical data of 87 EPWs with PH and 100 EPWs without PH undergoing vaginal delivery were collected. The risk factors of PH were analyzed by logistic regression analysis. Results Elderly primipara,>40 gestational weeks, body mass index≥25 kg/cm~2, newborn weight ≥3.5 kg, and third stage of labor ≥15 minutes were associated with higher PH(P<0.01 or 0.05). Multiple logistic regression analysis showed that newborn weight ≥3.5 kg, and third stage of labor ≥15 minutes were independent risk factors of PH(P<0.01). Conclusion The newborn weight ≥3.5kg and third stage of labor ≥15 minutes are the main risk factors for 87 EPWs with PH.更多还原
