前置胎盘危险因素及妊娠结局37例研究

目的探讨前置胎盘的危险因素及对妊娠结局的影响。方法对我院收治的37例前置胎盘病例进行回顾性分析,并与同期50例正常产妇作对照。结果研究组孕产妇年龄、孕产次、流产次数均高于对照组,有剖宫产史者和前置胎盘史者所占比例也明显高于对照组(P<0.05或P<0.01),剖宫产率、产科并发症以及新生儿窒息率等均高于对照组(P<0.01)。结论前置胎盘的形成与多种因素有关,可导致不良的妊娠结局,加强产前保健可以降低前置胎盘发生率,也有利于降低早产率、剖宫产率以及新生儿窒息率。

Analysis of 37 cases of placenta previa risk factors and pregnancy outcome

Objective To investigate the risk factors and pregnancy outcome of placenta previa.Methods 39 cases of placenta previa cases in the hospital were retrospectively analyzed,and made the same period 50 cases of normal maternal as control group.Results In placenta previa group,maternal age,maternal time and the number of abortions were higher than control group,the proportion of maternal with history of cesarean section and placenta previa history was also significantly higher（P0.05 or 0.01）,the rate of cesarean section,obstetric complications and neonatal asphyxia rate were higher than that of the control group（P0.05）.Conclusion Variety of factors related to the formation of placenta previa,and placenta previa could lead to adverse pregnancy outcomes.Strengthen prenatal care could reduce the incidence of placenta previa,and also help to reduce the rate of preterm birth,cesarean section rate and neonatal asphyxia.
