Term neonates (N = 35) with an one minute Apgar score of greater than or equal to 8 and mean umbilical artery pH values within normal were monitored by pulse oximetry. SaO2 monitoring started one minute after delivery. The initial SaO2 ranged from 40 to 75%. Neonates with a SaO2 above 80% five minutes after delivery remained untreated, neonates with a SaO2 below 80% received mask CPAP (figure 1). The initial difference in SaO2 between the groups was statistically significant (p less than 0.05). Mean umbilical artery pH and one, five and ten minutes Apgar score values were statistically not significant between the groups (p greater than 0.05). CPAP had been terminated as soon as SaO2 had reached 90%. This had been the lowest value monitored in spontaneously breathing neonates one day after delivery. Our findings indicate that neonates may sustain prolonged periods of decreased SaO2 which had not been detected by umbilical artery pH nor by the Apgar score. SaO2 monitoring by pulse oximetry served as a valuable method in the immediate newborn evaluation.
对35名足月儿进行脉搏血氧饱和度监测，这些新生儿1分钟阿氏评分大于或等于8分，平均脐动脉pH值在正常范围内。出生后1分钟开始监测血氧饱和度（SaO2）。初始SaO2范围为40%至75%。出生后5分钟时SaO2高于80%的新生儿未接受治疗，SaO2低于80%的新生儿接受面罩持续气道正压通气（CPAP）（图1）。两组之间初始SaO2的差异具有统计学意义（p<0.05）。两组之间的平均脐动脉pH值以及1分钟、5分钟和10分钟的阿氏评分值无统计学意义（p>0.05）。一旦SaO2达到90%，即停止CPAP。这是出生后一天自主呼吸新生儿监测到的最低值。我们的研究结果表明，新生儿可能会经历长时间的SaO2降低，这在脐动脉pH值和阿氏评分中均未被检测到。脉搏血氧饱和度监测在新生儿即刻评估中是一种有价值的方法。
