目的对前置胎盘危险因素进行分析。方法选取医院妇产科接诊发现前置胎盘的产妇200例为研究对象,根据前置胎盘的类型分为轻度组(68例)及重度组(132例),根据产妇有无出血分为出血亚组(121例)和无出血亚组(79例),对其发病因素、临床表现、诊断、治疗方式和妊娠结果进行系统的回顾性分析。选取同阶段住院90例胎盘正常产妇作为对照组,对前置胎盘危险因素进行相关性分析。结果高龄、经产、肥胖、吸宫刮宫等宫腔操作均为前置胎盘发病的相关因素,其中人工流产是前置胎盘的高危因素(P<0.01)。结论根据前置胎盘类型难以有效预测妊娠结局,通过期待治疗,延长胎龄并适时终止妊娠,有助于保证母婴生存质量,降低孕产妇和围产儿的病死率。
Objective To analyze the risk factors of placenta previa. Methods 200 cases of fetuses with placenta accreta placenta accreta found in hospital were divided into mild group (68 cases) and severe group (132 cases) according to the type of placenta previa. Bleeding subgroup (121 cases) and no bleeding subgroup (79 cases) were retrospectively analyzed on the incidence, clinical manifestations, diagnosis, treatment and pregnancy outcome. Ninety normal pregnant women with placenta in the same stage were selected as the control group, and the risk factors of placenta previa were analyzed. Results The elderly, obstetrics and gynecology, obstetrics and gynecology, uterine curettage and other uterine cavity operation were related factors of placenta previa, of which induced abortion was the risk factors of placenta previa (P <0.01). Conclusion According to the type of placenta previa, it is difficult to predict pregnancy outcome effectively. Expectant treatment, prolonged gestational age and timely termination of pregnancy help to ensure the quality of life of pregnant women and infants and reduce the mortality rate of pregnant women and perinatals.
