胎儿窘迫与新生儿窒息关系的研究

目的探讨胎儿窘迫与新生儿窒息的关系。方法对2053例产妇中因胎心率异常、羊水污染及胎儿电子监护诊断的胎儿窘迫及出生后Apgar评分进行分析。结果(1)胎心率与羊水均异常者新生儿窒息率可达40.32%;重度窒息率达11.29%;(2)胎心率减慢程度与新生儿窒息率密切相关,胎心率低于60次/min,新生儿重度窒息率达61.54%;(3)胎儿窘迫持续时间与新生儿窒息率呈正相关,胎儿窘迫超过60min,新生儿窒息率可达88.33%,与胎儿窘迫少于30min者相比,差异非常显著(P<0.01)。结论胎儿窘迫是新生儿窒息的先兆,通过对胎心率及羊水性状综合分析,可以对新生儿窒息发生的可能性做出预先判断,以便提早防范。

Study on the relationship between fetal distress and neonatal asphysia

Objective To investigate the relationship between fetal distress fetal heart rate abnormality,amniotic fluid contamination and neonatal asphysia.Methods The fetal distress caused by fetal fetal heart rate abnormality,amniotic fluid contamination and identified by electric monitor and Apgar score after birth in 2 053 parturients was analyzed.Results (1) The rate of neonatal asphipsia was 40.32% in parturients whose fetal heart rate and amino fluid were all abnormal,in which the severe neonatal asphysia accounted for 11.29%.(2) The degree of fetal heart rate decrease was closely related with neonatal asphysia.When the fetal hear rate was lower than 60 times/min,the severe neonatal asphysia rate would reach to 61.54%.(3) The duration of neonatal distress was positively correlated with the rate of fetal asphysis.When the duration was over 60 minutes,the rate of neonatal asphysia would reach to 88.33%.Conclusion Monitoring fetal hear rate and amniotic fluid can play an important role in forecasting fetal distress and preventing neonatal asphysia.
