Hyperoxia Clinical Trial
— INCPBOfficial title:
Effect of Intermittent Normoxic Cardiopulmonary Bypass on Myocardial Reperfusion Injury in Adult Valve Replacement
This study aims to determine the effect of intermittent normoxic cardiopulmonary bypass (CPB) on inflammatory response, oxidative stress and myocardial reperfusion injury in adult patients undergoing valve replacement. The investigators hypothesized that nuclear factor kappa B (NFkB) was involved in regulating gene expression of myocardial inflammatory factor.
