31 CEREBRAL PERFUSION IN NEONATES UNDERGOING REPAIR OF COMPLEX CONGENITAL HEART DEFECTS IS DETERMINED BY CARBON DIOXIDE PREOPERATIVELY BUT BY BLOOD PRESSURE POSTOPERATIVELY.

Abstract

BackgroundPreoperative studies of neonates with congenital heart disease have demonstrated that increased pCO2 results in increased cerebral perfusion, while hyperventilation with lower levels of pCO2 results in both less cerebral...
