Hemolysis and Inflammatory Response to Extracorporeal Circulation during On-Pump CABG: Comparison between Roller and Centrifugal Pump Systems
Objective: To compare the perioperative incidence rates of hemolysis and inflammatory
response in patients undergoing coronary artery bypass grafting with the two
main types of cardiopulmonary bypass, centrifugal and roller pumps, and
establish correlations among hemolytic and inflammatory changes.Methods: This was a prospective, randomized trial of 60 patients assigned to either
roller pump (G1, n=30) or centrifugal pump (G2, n=30) bypass. Markers of
hemolysis (serum haptoglobin, lactate dehydrogenase [LDH]) and inflammation
(interleukin [IL]1 ß, IL-6, and TNF-α) were measured and
analyzed.Results: There was no sig ...
