StO2 may enable earlier perfusion assessment than lactate during CPB; hypothesis-generating and should not yet change practice without randomized validation.

Does near-infrared spectroscopy (StO2) correlate with standard hemodynamic and biochemical variables in patients undergoing cardiopulmonary bypass?
StO2 measured by near-infrared spectroscopy is a reliable, noninvasive monitor of perfusion that identifies perfusion deficits earlier than lactate or base deficit in patients undergoing cardiopulmonary bypass.
Putnam et al. (2007) conducted an observational in Cardiopulmonary bypass (n=40). Near-infrared spectroscopy for regional tissue oxygenation saturation (StO2) vs. Standard hemodynamic and biochemical variables (lactate, base deficit) was evaluated on Relationship of StO2 to established parameters (lactate, base deficit, oxygen delivery). Regional tissue oxygenation saturation (StO2) using near-infrared spectroscopy identified perfusion deficits earlier than lactate by an average of 93.9 minutes in patients undergoing CPB.
