摘 要: | 目的探讨前置胎盘发病的高危因素。方法回顾性分析198例前置胎盘病例(病例组)和214例随机抽取的单胎产妇(对照组)的临床资料。结果前置胎盘组年龄≥30岁的产妇人数大于对照组,年龄≥30岁时前置胎盘的发病率明显增高(OR 1.76,95%CI 1.20~2.60),人工流产次数≥2(OR,2.68,95%CI1.35~5.33)、既往剖宫产(OR 1.89,95%CI 1.23~3.11)均是前置胎盘的高危因素。年龄和既往孕次对前置胎盘的发生可能有叠加影响,不同胎盘类型之间年龄、既往孕次、既往产次、人工流产次数和既往剖宫产比较,差异无统计学意义。结论产妇年龄≥30岁、人工流产次数≥2、既往剖宫产是前置胎盘的高危因素,上述高危因素与胎盘类型之间无明显关联。

Abstract: | Objective To explore the risk factors of placenta previa.Methods 198 cases of placenta previa(case group) and 214 cases of single fetal drawn-out randomly as control(control group) were retrospectively analyzed.Results The maternal ages of case group were significantly higher than those of control group,and the morbidity of placenta previa increased greatly(OR1.76,95%CI 1.20-2.60) when ages exceeded 30.Abortion times more than 2(OR 2.68,95%CI1.35-5.33) and cesarean delivery history(OR 1.89,95%CI 1.23-3.11) were the other risk factors of placenta previa happening.Age and gravidity might produce additive influences on the placenta previa occurance.The age,gravidity,parity,induced abortion and cesarean delivery times among different types of plancenta showed no statistical differences.Conclusion Maternal age≥30years,the number of abortion≥2,and previous cesarean section are high risk factors of placenta previa.No significant association between the risk factors and the type of placenta. |
