胎盘早剥患者发生产后出血的影响因素

Influencing factors of postpartum hemorrhage in patients with placental abruption

目的:分析胎盘早剥患者发生产后出血的影响因素。方法:回顾性分析2018年1月至2021年1月于该院分娩的60例胎盘早剥患者的临床资料,统计胎盘早剥患者产后出血发生情况,并对产后出血的影响因素进行单因素及多因素分析。结果:经统计,60例胎盘早剥患者发生产后出血21例,发生率为35.00%(21/60);发生产后出血患者的年龄、孕周、产次、甲状腺功能减退、胎膜早破情况等与未发生产后出血患者比较,差异均无统计学意义(P>0.05);发生产后出血患者的胎盘早剥分级、胎盘位置、子痫前期、绒毛膜羊膜炎、早产等与未发生产后出血患者比较,差异均有统计学意义(P<0.05);Logistic多因素分析结果显示,胎盘早剥分级Ⅱ级、胎盘位置在后壁、合并子痫前期、合并绒毛膜羊膜炎、早产均为胎盘早剥患者发生产后出血的危险因素(OR>1,P<0.05)。结论:胎盘早剥患者发生产后出血的风险较高,且胎盘早剥分级Ⅱ级、胎盘位置在后壁、合并子痫前期、合并绒毛膜羊膜炎、早产是其发生产后出血的危险因素。

Objective:To analyze influencing factors of postpartum hemorrhage in patients with placental abruption.Methods:The clinical data of 60 patients with placental abruption who were delivered in our hospital from January 2018 to January 2021 were retrospectively analyzed.The incidence of postpartum hemorrhage was statistically analyzed.Further,the influencing factors of postpartum hemorrhage were analyzed by univariate analysis and multivariate analysis.Results:According to statistics,21 cases of postpartum hemorrhage occurred in 60 patients with placental abruption,and the incidence rate was 35.00%(21/60).There were no significant differences in age,gestational age,parity,hypothyroidism,and premature rupture of membranes between the patients with postpartum hemorrhage and those without postpartum hemorrhage(P>0.05).However,there were significant differences in the placental abruption grading,placental location,preeclampsia,chorioamnionitis,and premature birth between the patients with postpartum hemorrhage and those without postpartum hemorrhage(P<0.05).Logistic multivariate analysis showed that placental abruption grade II,posterior wall of placenta,preeclampsia,chorioamnionitis,and premature birth were all risk factors for postpartum hemorrhage in the patients with placental abruption(OR>1,P<0.05).Conclusions:The patients with placental abruption are at higher risk of postpartum hemorrhage.Further,placental abruption grade II,posterior wall of placenta,combined preeclampsia,combined chorioamnionitis and premature birth are the risk factors for placental abruption.
