OBJECTIVE
To determine cerebral regional tissue oxygen saturation (CrSO2), renal regional tissue oxygen saturation (RrSO2), and splanchnic regional tissue oxygen saturation (SrSO2) values in healthy term infants.
STUDY DESIGN
Near-infrared spectroscopy was used to simultaneously measure CrSO2, RrSO2, and SrSO2 continuously for a 1-hour period on the first and second days of life.
RESULTS
A total of 41 subjects were monitored out of which complete data were available for 38 subjects. Mean CrSO2 was 78.2 ± 7.9% on first day; 78.3 ± 6.1% on second day (p = 0.95). Mean RrSO2 was 92.1 ± 5.3% on first day; 88.9 ± 5.9% on second day (p < 0.01). Mean SrSO2 was 69.9 ± 12.1% on first day and 75.3 ± 12.4% on second day (p = 0.02).
CONCLUSION
There appears to be consistency in rSO2 values in healthy newborns. CrSO2 was similar on both days. Differences observed in RrSO2 and SrSO2 between days may represent a shift in somatic blood flow distribution taking place during the first day of life.
目的
测定健康足月儿的脑局部组织氧饱和度（CrSO2）、肾局部组织氧饱和度（RrSO2）和内脏局部组织氧饱和度（SrSO2）值。
研究设计
采用近红外光谱法在出生第一天和第二天连续1小时同时测量CrSO2、RrSO2和SrSO2。
结果
共监测41名受试者，其中38名受试者有完整数据。第一天平均CrSO2为78.2±7.9%；第二天为78.3±6.1%（p = 0.95）。第一天平均RrSO2为92.1±5.3%；第二天为88.9±5.9%（p < 0.01）。第一天平均SrSO2为69.9±12.1%，第二天为75.3±12.4%（p = 0.02）。
结论
健康新生儿的rSO2值似乎具有一致性。两天的CrSO2相似。两天间RrSO2和SrSO2的差异可能代表出生第一天体循环血流分布的变化。
