Background: Determining the factors associated with increased risk of transfusion in coronary artery bypassgraft (CABG) surgery can help to decrease the rate of transfusion. This study was performed to determine therate of blood transfusion in our CABG surgeries and the clinical and demographic variables associated withincreased risk of blood transfusion.Methods: Data were prospectively collected from patients undergoing CABG surgery in Emam Reza Hospitalaffiliated to Mashhad University of Medical Sciences in Mashhad, Iran from March 2005 and April 2006. Patients'variables including age, sex, height, weight, body mass index, surface body, estimated blood volume and preoperativehemoglobin concentration in relation to the need for blood transfusion were evaluated.Results: Transfusion rate was 77.6%. Whole blood transfusion rate was more than that of packed red bloodcells. In 70% of patients, transfusion was 1-2 units. The prediction rule included surgeon and height of patients.Conclusion: This study and other transfusion guidelines help to change individual physician behavior and restrictfactors in relation to the need for blood transfusion in CABG, such as hemoglobin. These changes result ina major reduction in the transfusion rate.
