目的:探讨前置胎盘发病特征,危险因素及妊娠结果。方法:选取2013年11月到2015年11月于我院分娩的前置胎盘孕妇共56例为观察组,同期入院非前置胎盘孕妇56例为对照组,实施临床分析。结果:两组孕妇孕期并发症及分娩结局对比时,观察组与对照组产前出血、剖宫产、胎盘植入及产后出血等发生率对比具明显性差异(P<0.05);观察组三类型孕妇妊娠结局对比中,观察组完全性、部分性、边缘性前置胎盘三组中各组早产儿、阴道分娩、产后出血、术后输血等发生率对比具显著性差异,有统计意义(P<0.05);凶险性及普通性前置胎盘分娩时及分娩后情况对比中,两组分娩孕周、术中用时、分娩输血、胎盘植入、产后出血等因素对比具显著性差异,有统计意义(P<0.05)。结论:前置胎盘发病因素具广泛性,高龄孕妇、剖宫产史等均可诱发前置胎盘;前置胎盘不同类型及不同风险性均会导致各危险因素增长,对妊娠结局具较大影响。
Objective: To investigate the incidence of placenta previa, risk factors and pregnancy outcomes. Methods: Fifty-six pregnant women with placenta previa who delivered in our hospital from November 2013 to November 2015 were selected as the observation group. 56 pregnant women with non-placenta previa at the same period were selected as the control group for clinical analysis. Results: Comparing pregnancy complications and delivery outcomes between the two groups, the incidence of prenatal bleeding, cesarean section, placenta accreta and postpartum hemorrhage were significantly different between observation group and control group (P <0.05). Observation group three Type pregnant women in the comparison of pregnancy outcomes, the observation group of complete, partial, marginal placenta previa, vaginal delivery, postpartum hemorrhage, postoperative blood transfusion were significantly different in the incidence of the three groups were statistically significant ( P <0.05). In contrast to the precarious and common placenta previa at delivery and after delivery, there were significant differences in gestational age, intraoperative time, delivery blood transfusion, placenta accreta and postpartum hemorrhage Statistical significance (P <0.05). Conclusion: The placenta previa has a wide range of risk factors, such as elderly pregnant women, history of cesarean section can induce placenta previa; placenta previa different types and different risks will lead to the growth of risk factors, have a greater impact on pregnancy outcomes .
