摘　　要：目的:分析剖宫产瘢痕子宫再次妊娠患者发生前置胎盘的影响因素。方法:回顾性分析2018年6月至2020年6月该院收治的150例剖宫产瘢痕子宫再次妊娠患者的临床资料,根据是否发生前置胎盘分为发生组20例和未发生组130例。设计基线资料调查表,收集两组基线资料,分析剖宫产瘢痕子宫再次妊娠患者发生前置胎盘的影响因素。结果:发生组剖宫产次数≥2次、有人工流产史、首次剖宫产切口位置为子宫下段、再次妊娠间隔时间<18个月占比均高于未发生组,差异有统计学意义(P<0.05);经Logistic回归分析结果显示,剖宫产次数≥2次、有人工流产史、首次剖宫产切口位置为子宫下段、再次妊娠间隔时间<18个月均为影响剖宫产瘢痕子宫再次妊娠患者发生前置胎盘的危险因素(OR>1,P<0.05)。结论:剖宫产次数≥2次、有人工流产史、首次剖宫产切口位置为子宫下段、再次妊娠间隔时间<18个月均为影响剖宫产瘢痕子宫再次妊娠患者发生前置胎盘的危险因素。Objective:To analyze influencing factors of placenta previa in subsequent pregnancy patients with scar uterus after cesarean section.Methods:The clinical data of 150 subsequent pregnancy patients with scar uterus after cesarean section admitted to the hospital from June 2018 to June 2020 were retrospectively analyzed.According to whether placenta previa occurred,they were divided into occurrence group(20 cases)and non-occurrence group(130 cases).A baseline data questionnaire was designed to collect the baseline data of the two groups.The influencing factors of placenta previa in these patients were analyzed.Results:The proportions of the number of cesarean section≥2,history of induced abortion,location of first cesarean section incision in the lower uterine segment,and the interval of subsequent pregnancy<18 months in the occurrence group were higher than those in the non-occurrence group,and the differences were statistically significant(P<0.05).The Logistic regression analysis showed that the number of cesarean section≥2,history of induced abortion,the location of the first cesarean section incision in the lower uterine segment,and the interval of subsequent pregnancy<18 months were all risk factors for placenta previa in the subsequent pregnancy patients with scar uterus after cesarean section(OR>1,P<0.05).Conclusions:The number of cesarean section≥2,history of induced abortion,the location of the first cesarean section incision in the lower uterine segment,and the interval of subsequent pregnancy<18 months are the risk factors for placenta previa in the subsequent pregnancy patients with scar uterus after cesarean section.
