This study was designed to elucidate the trends in cerebral venous oxygen saturation in cyanotics and acyanotics undergoing normothermic and hypothermic cardiopulmonary bypass (CPB) and its relationship to perfusion flow rates. ⋯ We conclude that patients undergoing normothermic CPB are at greater risk of cerebral desaturation. The cyanotics are at greater risk compared to acyanotics during normothermic CPB and during the re-warming phase of hypothermic CPB and require an individualised increased perfusion flow rate.
