近5年医源性早产原因分析

摘要

目的：：探讨医源性早产发生原因及提升早产儿存活率的方法。方法：回顾分析某院2009年~2013年间收治的医源性早产病例，统计其早产原因，比较不同干预措施对围产儿及产妇结局的影响。结果：2009年1月~2013年12月期间某院接收医源性早产者582例，分别占到分娩总数和早产总数的6.5%、43.9%；妊娠高血压、前置胎盘是医源性早产的主要原因，分别占到总数的31.9%、18.5%；产前定时产检可以有效提升医源性早产母婴结局，其产后出血及新生儿窒息率分别控制在3.8%、0.7%，无围产儿死亡例，优于不定时产检组及无产检组观察组；剖宫产为医源性早产的主要分娩方式，占到总数的88.8%。结论：医源性早产占早产比率呈逐年递增趋势，妊娠高血压和前置胎盘为主要原因，通过定时产检和选择合适的分娩方式可以有效提升医源性早产母婴结局。%Objective:To discuss the reasons of iatrogenic preterm labor and methods to raise live birth rate of premature.Methods:Retrospectively analyze iatrogenic preterm labor cases received by a hospital from 2009 to 2013,collect the reasons and compare the influences of different intervention measures on maternal and neonatal outcomes.Results:A hospital received 582 cases of iatrogenic preterm labor,accounting for 6.5%and 43.9% of the total number of delivery and total number of preterm birth.Hypertension of pregnancy and placenta praevia are the main reasons of iatrogenic preterm labor,accounting for 31.9% and 18.5% of the to-tal number.Regular prenatal check can effectively improve maternal and neonatal outcomes,postpartum hemorrhage and neonatal asphyxia were controlled at 3.8% and 0.7%,better than cases without prenatal check.The uterine-incision delivery was the main delivery mode of iatrogenic preterm labor,accounting for 88.8% of the total number.Conclusion:The proportion of iatrogenic preterm labor in total number of preterm birth increases gradually,hypertension of pregnancy and placenta praevia are the main reasons of iatrogenic preterm labor,and regular prenatal check and proper delivery mode can effectively improve maternal and neonatal outcomes.
