Does blood transfusion affect intermediate survival after coronary artery bypass surgery

Background:The aim of this study was to investigate the impact of transfusion of blood products on intermediate outcome after coronary artery bypass surgery.Patients:Complete data on perioperative blood transfusion in patients undergoing coronary artery bypass surgery were available from 2001 patients who were operated at our institution.Results:Transfusion of any blood product (relative risk = 1.678, 95% confidence interval = 1.087–2.590) was an independent predictor of all-cause mortality. The additive effect of each blood product on all-cause mortality (relative risk = 1.401, 95% confidence interval = 1.203–1.630) and cardiac mortality (relative risk = 1.553, 95% confidence interval = 1.273–1.895) was evident when the sum of each blood product was included in the regression models. However, when single blood products were included in the regression model, transfusion of fresh frozen plasma/Octaplas® was the only blood product associated with increased risk of all-cause mortality (relative risk = 1.692,...
