摘　　要：目的通过监测产程中胎儿血氧饱和度(FSaO2)来研究胎儿氧合及酸碱平衡状态、预测胎儿窘迫的发生率。方法62例产妇在其第一产程活跃期及第二产程进行胎心电子外监护及胎儿血氧饱和度监测,依据分娩后新生儿Apgar评分和脐血血气分析结果计算两种监护方法的敏感度、特异度、阳性预期值、阴性预期值及准确率。结果第一产程活跃期及第二产程的胎儿血氧饱和度均值有统计学差异;胎儿血氧饱和度与脐血血气有显著相关;以FSaO2≤30%为标准诊断胎儿窘迫,其敏感性、特异性、阳性预测值、阴性预测值及准确率分别为90%、96.2%、81.8%、96.2%、95.2%。结论胎儿血氧饱和度可有效反映胎儿氧合及酸碱平衡状态,其监测方法可提高诊断胎儿窘迫的准确性。Objective To study the oxygenation and acid-base balance in fetus for prediction of fetal distress by monitoring the incidence rate of fetal oxygen saturation （FSaO2） during intrapartum. Methods External electronic FSaO2 monitoring was performed during the active phases of the first and second labor stages in 62 parturients. Sensitivity, specificity, positive and negative predictive values of the monitoring methods were determined based on the Apgar score and cord artery blood gases. Results The mean FSaO2 was significantly higher during the active phase of the first stage than during the active phase of the second stage. FSaO2 was significantly correlated with pH, PO2, PCO2 and base excess （BE） of the cord blood. The diagnostic sensitivity, specificity, positive and negative predictive value of 30% cutoff for intrauterine fetal distress were 90%, 96.2%, 81.8%, 96.2% and 95.2%, respectively. Conclusion FSaO2 monitoring is an effective method for the diagnosis of intrauterine fetal distress.
