Why the study?
Evidence on the prognostic importance of baseline and intraoperative rSO2 decreases is limited in cardiac surgery patients who received interventions to correct rSO2 decreases.
Does the severity of intraoperative decrease in cerebral oxygen saturation (AUT50) predict adverse outcomes in cardiac surgical patients who receive interventions to correct rSO2 decreases?
Does the severity of intraoperative decrease in cerebral oxygen saturation (AUT50) predict adverse outcomes in cardiac surgical patients who receive interventions to correct rSO2 decreases?
In cardiac surgery patients, greater severity of intraoperative cerebral oxygen desaturation is independently associated with adverse outcomes even when interventions are applied to correct the desaturation.
No takes yet. Share an insight, caveat, or question.
rSO2 values may associate with morbidity despite interventions; leaves open whether monitoring alters outcomes in prospective trials.
