凶险性前置胎盘与非凶险性前置胎盘临床分析

Clinical Analysis Between the Pernicious Placenta Previa and Non-pernicious Placenta Previa

目的探讨凶险性前置胎盘与非凶险性前置胎盘发病相关因素及其母婴妊娠结局。方法终止妊娠的342例前置胎盘的临床患者资料作为研究对象,根据是否有剖宫产病史分为凶险性前置胎盘组及非凶险性前置胎盘组,比较两组的产科危险因素及其母婴妊娠结局。结果凶险性前置胎盘组的早产儿发生率、新生儿窒息率、死胎率均明显高于非凶险性前置胎盘组,两组比较差异有统计学意义(P<0.05)。结论普及性知识和产科相关知识,减少流产率,提倡阴道分娩,减少孕妇对自然分娩的恐惧心理,以及医护人员严格掌握剖宫产指征等是预防凶险性前置胎盘的关键。

Objective To investigate the pathogenic related factors of pernicious placenta previa and non-pernicious placenta previa and its pregnancy outcome. Methods Collecting the past clinical data of 342 placenta previa patients whose pregnancy were terminated,making a retrospective analysis of the related factors of the pernicious placenta previa and non-pernicious placenta previa,and comparing the characteristics of them and the pregnancy outcomes. Results The pernicious placenta previa group has a significantly higher percentage of the incidence of premature infants,neonatal asphyxia and stillbirth rate. Difference between the two groups has a statistical significance in comparison（ P〈 0. 05）. Conclusion The popularization of sexual knowledge and obstetrics,the reduce of abortion rate,the avocation of vaginal delivery,the reduce of pregnant women＇s fear of spontaneous labor,and the strict grasp of caesarean section are the key points of the prevention of pernicious placenta previa.
