瘢痕子宫再次妊娠孕妇前置胎盘发生状况及其影响因素分析

Analysis on the Occurrence of Placenta Previa in Re-Pregnant Women with Scar Uterus and Its Influencing Factors

目的分析瘢痕子宫再次妊娠孕妇前置胎盘发生状况及其影响因素。方法回顾性分析2018年4月至2020年5月我院68例瘢痕子宫再次妊娠孕妇的临床资料,统计前置胎盘发生情况,分析前置胎盘发生的相关影响因素。结果68例瘢痕子宫再次妊娠孕妇发生前置胎盘3例,发生率为4.41%。发生组的剖宫产次数多于未发生组,再次妊娠间隔时间短于未发生组,有盆腔炎史比例高于未发生组(P<0.05)。Logistic回归分析显示,剖宫产次数多、再次妊娠间隔时间短、有盆腔炎史为瘢痕子宫再次妊娠孕妇发生前置胎盘的影响因素(OR>1,P<0.05)。结论瘢痕子宫再次妊娠孕妇有一定的前置胎盘发生风险,剖宫产次数多、再次妊娠间隔时间短、有盆腔炎史是前置胎盘发生的影响因素。

Objective To analyze the occurrence of placenta previa in re-pregnant women with scar uterus and its influencing factors.Methods The clinical data of 68 cases of re-pregnant women with scar uterus in our hospital from April 2018 to May 2020 were analyzed retrospectively.The occurrence of placenta previa was counted,and the related influencing factors for the occurrence of placenta previa were analyzed.Results 3 cases of placenta previa occurred in 68 re-pregnant women with scar uterus,and the incidence rate was 4.41%.The cesarean section times in the occurrence group was more than that in the non-occurrence group,the re-pregnancy interval was shorter than that in the non-occurrence group,and the proportion of history of pelvic inflammatory diseases was higher than that in the non-occurrence group(P<0.05).Logistic regression analysis showed that high frequency of cesarean section,short re-pregnancy interval and history of pelvic inflammatory diseases were influencing factors for the occurrence of placenta previa in re-pregnant women with scar uterus(OR>1,P<0.05).Conclusions Re-pregnant women with scar uterus have a certain occurrence risk of placenta previa.High frequency of cesarean section,short re-pregnancy interval and history of pelvic inflammatory diseases are the influencing factors for the occurrence of placenta previa.
