Cerebral oxygenation saturation in childhood: difference by age and comparison of two cerebral oximetry algorithms
Authors' conclusion
In pediatric patients undergoing non-cardiac surgery, rSO2 values differed across the three age groups, and the pattern of these differences varied between the two oximeters employing different algorithms.
Study context
- Population
- Children undergoing non-cardiac surgery
- Participants
- 78 children
- Exposure
- Infants vs toddlers vs schoolchildren; tNIRS-1 vs INVOS 5100C
- Infantsn = 26
- Toddlersn = 26
- Schoolchildrenn = 26
- Outcome
- Regional cerebral oxygen saturation (rSO2) by age group, measured with tNIRS-1 (time-resolved spectroscopy) and INVOS 5100C
Methodological detailscomparison of two cerebral oximeters
- Comparison of two cerebral oximeters
Main finding
As reported in the abstract
rSO2 by age group
- INVOS 5100C: rSO2 significantly lower in infants than in other patients
- tNIRS-1: rSO2 higher in toddlers than in other groups
Observational data: associations, not effects.
Further findings
Correlation between tNIRS-1 and INVOS 5100C rSO2
- Moderate correlation (r)
- 0.41
- INVOS 5100C values approximately higher, with ceiling effect
- 20%
Physiological factors influencing rSO2
- INVOS 5100C values affected by BP; tNIRS-1 values affected by MAC of sevoflurane
