Advances in extracorporeal perfusion techniques, the intra-aortic balloon pump, and organ preservation have renewed interest in the clinical usage of pulsatile cardiopulmonary bypass and membrane oxygenation in cardiac surgery. We have tried pulsatile pump + membrane oxygenator (Group 1), centrifugal pump + membrane oxygenator (Group 2), pulsatile pump + bubble oxygenator (Group 3), centrifugal pump + bubble oxygenator (Group 4) in 80 open heart patients and compared the data obtained before, at 30 minutes and after cardiopulmonary bypass. Our results have shown that each have its own positive and negative physiological consequences after their usage. Although it is significantly destructive to blood cells, pulsatile pumping improves the myocardial performance, provides optimal cerebral hypothermia and blood oxygenation; centrifugal pumping and membrane oxygenation are the best devices when hemolysis is the primary concern of the cardiac surgeon.
