摘　　要：目的:分析自然分娩初产妇宫缩乏力性产后出血(PPH)的影响因素.方法:选取2021年1月至2022年12月本院收治的73例自然分娩初产妇作为研究对象.根据是否发生宫缩乏力性PPH将其分为宫缩乏力性PPH组(n=25)和无宫缩乏力性PPH组(n=48).收集产妇临床资料,记录宫缩乏力性PPH病例,采用多元因素非条件回归分析探讨其影响因素.结果:73例产妇宫缩乏力性PPH发生率为34.25%(25/73);多因素非条件Logistic回归分析结果显示,其独立危险因素包括年龄≥35岁、胎盘异常、第三产程时间≥15min、新生儿体重≥4kg、不良心理状态及母婴未早期接触吮吸(OR>1,P<0.05).结论:宫缩乏力性PPH发生的独立危险因素包括产妇超出最佳育龄期(≥35岁)、胎盘异常、第三产程时间过长(≥15min)、新生儿体重偏高(≥4kg)、心理状态不佳及母婴未早期接触吮吸.需针对上述影响因素,采取相应干预措施,以降低宫缩乏力性PPH发生率.Objective:To analyze the influencing factors of postpartum hemorrhage(PPH)caused by uterine atony in primiparous women undergoing natural delivery.Methods:A total of 73 primiparas who gave birth naturally from January 2021 to December 2022 in our hospital were selected in this study.They were divided into uterine atony PPH group(n=25)and non-uterine atony PPH group(n=48)based on whether uterine atony PPH has occurred.Clinical data were collected,and cases of PPH due to uterine inertia were recorded.Multivariate unconditional logistic regression analysis was used to explore the influencing factors.Results:The incidence of PPH due to uterine atony in 73 parturient women was 34.25%(25/73).Multivariate unconditional logistic regression analysis showed that the independent risk factors included age≥35 years old,placental abnormalities,third stage of labor time≥15 minutes,newborn weight≥4kg,adverse psychological state,and lack of early maternal and infant contact and sucking(OR>1,P<0.05).Conclusions:The independent risk factors for PPH due to uterine inertia include maternal age beyond the optimal reproductive age(≥35years),placental abnormalities,prolonged third stage of labor(≥15 minutes),high birth weight of the newborn(≥4kg),poor psychological status,and lack of early maternal and infant contact and sucking.Relevant interventions should be taken to address these factors to reduce the incidence of PPH due to uterine inertia.
