title: Cerebral, renal, and splanchnic tissue oxygen saturation values in healthy term newborns.
abstract: 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.
  
  
  METHODS
  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).
  
  
  CONCLUSIONS
  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.
