Official Title: Changes of Lactate Levels During Cardiopulmonary Bypass in Pediatric Undergoing Cardiac Surgery: Possible Early Marker of Morbidity and Mortality
Brief Summary: Many variables measured in critically ill patients have been used to estimate severity of disease, prognosticate morbidity and mortality, evaluate costs of treatment, and finally indicate specific treatment and monitor the adequacy of treatment and its timing. It is unlikely that one measurement can replace all of these, but in the remainder of this manuscript the investigators will show that lactate levels may come close. Although in our mind strongly linked to tissue hypoxia, lactate levels follow many more metabolic processes not related to tissue hypoxia and, therefore, subject to many disturbances found in various clinical situations
