增加胎心监护检查频率对降低新生儿窒息率的影响

目的评价增加胎心监护检查频率方法的临床意义,探讨降低胎监假阳性率的方法,提高胎儿宫内窘迫的诊断,降低新生儿窒息率.方法取2001年在我院分娩的1087例产妇为观察组,孕37w后住院期间实行每天一次胎监检查,产时进行连续监护,1997年分娩的1091例产妇为对照组,孕37w后住院期间每周一、两次胎监检查,产时间断监护.用x2统计两组胎监假阳性率、剖宫产率、新生儿窒息率,回顾分析胎监异常与临床结局的关系.结果2001年组的因胎监异常剖宫产率为20.6%,假阳性率27.45%,新生儿窒息率6.53%,1997年组因胎监异常剖宫产率为26.4%,假阳性率为46.51%,新生儿窒息率11.73%,两组相比有显著性差异P＜0.01.结论增加胎监检查频率的方法能降低胎监的假阳性率,降低新生儿窒息率.

The effect on the incidence of neonate asphyxia by increasing the frequent of fetal monitoring

Objective: To evaluate the clinical significance of increasing the frequent of fetal monitoring in order to lower the false positive rate of fatal monitoring and increase diagnostic rate of fetal distress, thereby lowering the incidence of neonatal asphyxia.Methods: 1087 cases of pregnant women who delivered in our hospital in the year of 2001 were studied. They hade fatal monitoring every day after 37 gestational weeks and were continuously monitored during delivery. 1091 cases of pregnant women who delivered in the year of 1997 were included as control, who had fatal monitoring one or two times a week after 37 gestational weeks and intermittently monitored during delivery. The relationship between the abnormality fatal monitoring and clinical results is retrospective analysis. The false positive rate of fetal monitoring, the cesarean rates and the incidence of neonate asphyxia were also counted.Result: The cesarean rates due to abnormal were 20.6%, false positive rates were 20.75%, neonatal asphyxia incidence was 6.53% in group 1 (2001). The figure were 26.4%, 46.51% and 11.73% in group 2 (1997) respectively. There is significant difference between these two groups. ( P <0.01).Conclusion: Increasing frequency of fatal monitoring can lower the false positive rate of fetal monitoring and lower the incidence of neonatal asphyxia.
