The purpose of this study was to document the oxygen saturation (SpO(2) ), general physical signs and laboratory characteristics during the first 30 min of life.
Forty healthy singleton full-term neonates delivered vaginally (n = 33) or by cesarean section (n = 7) were included in this prospective observational study. After delivery, the SpO(2) levels of the upper (right hand; 'preductal') and lower (dorsum of the right foot; 'postductal') extremities of the neonates lying on the servo-controlled radiant heater in the delivery room were measured simultaneously with oximeter probes (Oxiprobe BM-270) placed at 1, 5, 10, 15, 20, 25, and 30 min. The correlation between pre- and postductal SpO(2) level and different variables (vital signs, capillary refill time recorded at 1 and 15 min, cord pH and hemoglobin values, and Apgar scores at 1 and 5 min) was examined.
The 1 min pre- and postductal SpO(2) were 82.3 ± 7.34% and 79.08 ± 8.16% (P > 0.05), respectively. The preductal values at 5, 10, and 15 min were statistically higher than the postductal values (89.73 ± 6.01%, 93.43 ± 4.06%, and 94.53 ± 3.19% vs 85.53 ± 6.92%, 89.9 ± 4.91%, 92.83 ± 3.92%, respectively). SpO(2) was the same regardless of the mode of delivery. No correlations were found between pre- and postductal SpO(2) and other variables.
Oxygen saturation was not affected by mode of delivery, was independent of Apgar score, cord hemoglobin, cord pH, vital signs, and capillary refill time in the first few minutes of life, and did not reach 90% in the first 5 min of life in healthy full-term neonates.
本研究旨在记录出生后最初30分钟内的血氧饱和度（SpO₂）、一般身体体征和实验室特征。
本前瞻性观察性研究纳入了40例经阴道分娩（n = 33）或剖宫产（n = 7）的健康单胎足月新生儿。分娩后，使用血氧饱和度探头（Oxiprobe BM - 270）在产房的伺服控制辐射加热器上，于出生后1、5、10、15、20、25和30分钟同时测量新生儿上肢（右手；“导管前”）和下肢（右脚背；“导管后”）的SpO₂水平。研究了导管前和导管后SpO₂水平与不同变量（生命体征、1分钟和15分钟时记录的毛细血管再充盈时间、脐血pH值和血红蛋白值以及1分钟和5分钟时的阿氏评分）之间的相关性。
出生后1分钟时，导管前和导管后的SpO₂分别为82.3±7.34%和79.08±8.16%（P>0.05）。5分钟、10分钟和15分钟时导管前的值在统计学上高于导管后的值（分别为89.73±6.01%、93.43±4.06%和94.53±3.19%，对比85.53±6.92%、89.9±4.91%、92.83±3.92%）。无论分娩方式如何，SpO₂均相同。在导管前和导管后的SpO₂与其他变量之间未发现相关性。
血氧饱和度不受分娩方式影响，在生命最初几分钟内独立于阿氏评分、脐血血红蛋白、脐血pH值、生命体征和毛细血管再充盈时间，并且健康足月新生儿在出生后最初5分钟内未达到90%。
