Brief Summary

In cardiac operations, high values of blood lactate have been associated with bad outcomes if detected both during CPB and at the arrival in the intensive care unit (ICU) in adult patients. Many studies highlighted the potential role of hyperlactatemia on admission to the ICU as a marker for adverse outcome, and one study linked hyperlactatemia during CPB with postoperative morbidity and mortality. Evidence that both CENTRAL VENOUS SATURATION (ScVO2) and blood lactates during CPB are potential early predictors of morbidity and mortality in adult cardiac operations are still lacking.
