Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention
an alarm threshold at a value of 90% of the resting baseline cerebral saturation value (baseline - 10%) will be established. To minimize the probability of patients reaching significant decreases rSO2 values, interventions to improve cerebral oxygenation will be initiated according to the strategies described in the algorithm. The success and failure of these interventions will be noted. As in the Control group, the screen will remain blinded in the ICU and the intensivist will not see the values.
strategies to reverse decrease in rSO2
an alarm threshold at a value of 90% of the resting baseline cerebral saturation value (baseline - 10%) will be established. To minimize the probability of patients reaching significant decreases rSO2 values, interventions to improve cerebral oxygenation will be initiated according to the strategies described in the algorithm. The success and failure of these interventions will be noted. As in the Control group, the screen will remain blinded in the ICU and the intensivist will not see the values.
Control
the cerebral oxymetry screen will be blinded and changes in NIRS values will be unknown to the anesthesiologist. The management of the case will proceed as per normal local practice. The screen will remain blinded in the ICU and the intensivist will not see the values.
