Summary
Cardiac surgery with cardiopulmonary bypass (CPB), especially when oxygen delivery is low, is
associated with acute kidney injury. Unpublished data shows that renal oxygen delivery is
compromised during CPB due to low hematocrit and redistribution of blood flow away from the
kidneys. We wish to study if increased CPB flow can improve renal oxygenation.
Patients who develop cardiac failure after weaning from CPB will be treated as per our
departments routine with the inotropic agent milrinone, and measurements will be made before
and after treatment.
