Electronic fetal heart rate (FHR) monitoring is commonly used to assess fetal well-being during labor. Nonreassuring patterns in many cases are associated with normal fetal acid-base condition, leading to unnecessary operative intervention. Fetal pulse oximetry has several potential advantages over FHR monitoring because it assesses not only pulse, but also arterial oxygen saturation and tissue perfusion. We describe our preliminary experience with the Nellcor N-400 Fetal Oxygen Saturation Monitor and FS-10 Oxisensor in 73 subjects during active labor at term. The mean (+/- standard deviation) duration of monitoring was 161.4 +/- 106.0 minutes, with sensor contact achieved 67.3 +/- 22.5% of the time during labor. Data were successfully recorded in all patients, with a reliable signal obtained 50.1 +/- 21.6% of the time during labor. The mean fetal oxygen saturation was 57.9 +/- 10.0%. The potential for research and clinical applications appears promising with further sensor and monitor development.
电子胎儿心率（FHR）监测常用于评估分娩期间胎儿的健康状况。在许多情况下，令人担忧的模式与胎儿正常的酸碱状态相关，导致不必要的手术干预。胎儿脉搏血氧饱和度测定法相对于FHR监测具有几个潜在优势，因为它不仅能评估脉搏，还能评估动脉血氧饱和度和组织灌注。我们描述了在73名足月活跃期分娩的受试者中使用Nellcor N - 400胎儿血氧饱和度监测仪和FS - 10血氧传感器的初步经验。监测的平均（±标准差）持续时间为161.4±106.0分钟，分娩期间传感器接触时间占67.3±22.5%。所有患者的数据均成功记录，分娩期间50.1±21.6%的时间获得了可靠信号。胎儿血氧饱和度平均值为57.9±10.0%。随着传感器和监测仪的进一步发展，研究和临床应用的潜力似乎很有前景。
