羊水粪染71例临床分析

The Analysis of 71 Cases of Meconium-stained Amniotic Fluid

目的：探讨羊水粪染与新生儿窒息的关系。方法：严密观察６８２例产妇产程进展，进行胎心电子监护，评估羊水粪染程度、记录分娩方式及对新生儿进行Ａｐｇａｒ评分。结果：６８２例产妇中羊水粪染７１例，占１０．４％；羊水粪染中新生儿轻度窒息占２３．９％，重度窒息占８．４％；其中羊水Ⅲ度粪染者中新生儿窒息率占３５．９％；分娩时羊水粪染时间大于４小时者，新生儿窒息率占５３．６％；羊水粪染可增加产妇手术产率。结论：羊水粪染是胎儿在危险环境中的信号，是评估胎儿安危的一个重要指标。

Objective:To explore the relation between the degree of Meconium-stained Amniotic Fluid (MSAF) and neonatorum asphyxia.Methods:Observe the labor progression of 682 puerpera,monitor the foetus heart rates.evaluate the degree of MSAF,record the ways of labor and perform Apgar score on the newborns.Results:There were 71 cases of MSAF among the 628 puerpera making up 10.4% of the total.Among the 71 cases,the percentage of light neonatorum asphyxia was 23.9%;That of severe neonatorum asphyxia was 8.4%;Among the cases of the third degree MSAF,the rate of the newborns severe neonatorum asphyxia was 35.9%;For those newborns who were delivered 4 hours after MSAF,The rate of neonatorum asphyxia was 53.6%;MSAF increases the rate of surgical parturition.Conclusion:MSAF is a signal that the foetus is in danger.It is an important index to evaluate whether foetus is in safety or in danger.
