摘　　要：目的判断胎儿血氧监护仪诊断胎儿窘迫的准确性及安全性以及联合应用胎心监护的合理途径。方法对60例产妇在产程中同时进行胎心电子监护及胎儿血氧饱和度的监测,依据分娩后阿氏评分及脐血血气分析结果验证两种监测方法的特异性、准确率。结果胎儿血氧饱和度与脐血血气多项指标有显著相关性,并且与脐动脉血pH值呈线性回归。以胎儿血氧饱和度<30%为标准诊断胎儿窘迫,特异性为95.9%,准确率为95%。结论胎儿血氧饱和度可准确、迅速地反映胎儿宫内氧合状态及酸碱状态。胎儿电子监护与血氧饱和度监测联合应用,能更准确的诊断胎儿窘迫。Objective To explore reasonable route of diagnosis of fetal acidosis by combining FSaO2 monitoring system and electronic fetal monitoring （EFM）. Methods Continuous fetal oxygen saturation rate combining with external EFM was monitored at 60 term fetuses during all of stage, The two monitoring methods were validated with specificity and accuracy on the bases of Apgar score and cord artery blood gases analysis results. Results Fetal oxygen saturation rate was significantly correlated with pH, PO2, PCO2 and BE of cord artery blood gases, There was linear regression between fetal oxygen saturation rate and cord artery blood pH. With a 30% cutoff, predicting fetal acidosis of using fetal oxygen saturation monitoring system was more accurate than that of using external FHR monitoring.Specificity was 95.9% and accuracy was 95%. Conclusion FSaO2 monitoring is an efficient diagnostic method of fetal acidosis. Combining fetal oxygen saturation and EFM will be a better reasonable route of diagnosis of fetal acidosis.
