What are the common predictors of excessive blood use after coronary artery bypass grafting?
Common predictors of excessive blood use after coronary artery bypass grafting include patient demographics, such as age, gender, and co-morbidities, as well as the type and complexity of the procedure. Risk factors such as pre-operative hemoglobin, intra-operative hemodynamic parameters, and intra-operative transfusion of blood products have also been associated with the need for transfusion after coronary artery bypass grafting. Other predictors include the presence of cardiogenic shock, pre-operative hematocrit, pre-operative creatinine, and pre-operative packed red blood cell transfusion.
