The aim of the study is to provide preliminary assessment of the possibilities of fetal pulse oximetry as a method for monitoring of fetal pulse rate and oxygen saturation during labour. The study includes 65 pregnant women during active labour at term--all with one fetus and ruptured membranes. A system for fetal pulse oximetry is used, consisting of monitor Nellcor-N 400; oxygen sensor FS-14 and printer P-400 (Nellcor Puritan Bennett incorporation). Sensor is applied by mean dilatation of cervical channel 6.5 +/- 1.9 cm. Mean duration of monitoring of the pregnant woman is 104 +/- 68 minutes, range 30 to 180 min. The time of reliable signal quality is 83% for first stage of labour and 70% for second stage of labour. Mean SpO2 values are 47.1 +/- 9.8%. The conclusion is made that fetal pulse oximetry is an easy method to use, without side effects for mother and fetus. Mean SpO2 values are tower than in adults and vary inside wider range 35-55%.
本研究的目的是对胎儿脉搏血氧饱和度测定法作为分娩期间监测胎儿心率和血氧饱和度的一种方法的可能性进行初步评估。该研究纳入了65名足月活跃期分娩的孕妇——均为单胎且胎膜已破。使用了一种胎儿脉搏血氧饱和度测定系统，包括Nellcor-N 400监测仪、FS-14氧传感器和P-400打印机（Nellcor Puritan Bennett公司）。传感器通过平均宫颈扩张6.5±1.9厘米来应用。孕妇的平均监测时长为104±68分钟，范围为30至180分钟。第一产程可靠信号质量的时间为83%，第二产程为70%。平均SpO2值为47.1±9.8%。得出的结论是，胎儿脉搏血氧饱和度测定法是一种易于使用的方法，对母亲和胎儿均无副作用。平均SpO2值低于成年人，且在35 - 55%的较宽范围内变化。
