目的探讨剖宫产瘢痕子宫破裂的危险因素。方法收集2012年1月至2015年5月于暨南大学附属第一医院住院分娩的瘢痕子宫孕妇的临床资料进行回顾性分析,选取12例子宫破裂者为病例组,30例正常分娩者为对照组,采用秩和检验和多因素非条件Logistic回归分析在年龄、体质量指数(body mass index,BMI)、孕周、孕次、剖宫产次数、人工流产次数、瘢痕厚度、距前次剖宫产时间间隔、是否为巨大儿等因素中筛选瘢痕子宫破裂的危险因素。结果 Logistic回归分析结果显示BMI>26 kg/m~2、剖宫产产次>1次、再次分娩时间间隔≥4年是瘢痕子宫破裂的危险因素。结论超重、重复剖宫产、距前次剖宫产间隔时间长是瘢痕子宫破裂的危险因素,对此类孕妇应给予重视,预防子宫破裂的发生。
Objective To investigate the risk factors of uterine rupture in cesarean scar. Methods The clinical data of pregnant women with scar uterus delivered from January 2012 to May 2015 in the First Affiliated Hospital of Jinan University were retrospectively analyzed. Twelve cases of uterine rupture were selected as the case group and 30 cases of normal delivery as the control group , Using rank sum test and multivariate non-conditional Logistic regression analysis in age, body mass index (BMI), gestational age, gestational age, number of cesarean section, the number of induced abortion, scar thickness, from the previous cesarean section Production interval, whether giant children and other factors screening risk factors for uterine scar rupture. Results Logistic regression analysis showed that BMI> 26 kg / m ~ 2 and cesarean section was> 1 time. Reproductive time interval> 4 years was the risk factor of scar uterine rupture. Conclusions Overweight and repeated cesarean section, a long distance from the previous cesarean section, are the risk factors for uterine rupture of the scar. Precautions should be taken to prevent uterine rupture.
