回顾性分析干预性早产对母婴预后的影响

Influences of controlled premature delivery on mothers and newborns

目的了解早产发生的因素构成,探讨干预性早产对母婴预后的影响。方法回顾性分析283例早产病例的临床资料,并分析干预性早产与母婴预后的关系及干预性早产儿的孕周、体重与并发症的相关性。结果重度妊高征、妊娠期肝内胆汁淤积症(ICP)、前置胎盘等是造成早产的常见病因,相对于自然早产组,干预性早产儿并发症及死亡率明显降低(P<0.001),母亲产后出血和产褥热发生率也明显减少(P<0.01),随着孕周及体重的增加,干预性早产儿并发症及死亡率均明显降低(P<0.001)。结论适时选择干预性早产对减少围产儿并发症及死亡率、改善妊娠结局有益处。

Aim To understand the factors of controlled premature delivery and to detect its influences on mothers and newborns.Methods Data of 283 cases of premature delivery were analyzed retrospectively.The relation between controlled premature delivery and the prognosis of mothers and newborns,and the correlation between complication and gestational weeks and body weight were also analyzed.Results The common causes of premature delivery were severe PIH,ICP,placenta previa and so on.When compared with nature death birth,both of the complication and death rate of controlled premature infant decreased obviously（χ2=76.91,P0.001）,and the postpartum hemorrhage and the pyretogenesia of delivery reduced too（χ2=6.82,P0.01）.With the increase of gestational weeks and body weight,the complication and death rate of controlled premature infant decreased（P0.001）.Conclusions Choice of comtrolled premature delivery at the right moment can improve the pregnancy outcome and reduce the complication and death rate of perinatal babies.
