In our study, autologous blood donation significantly decreased the risk of homologous transfusion and homologous blood requirements in male cabg patients. We were not able to prove the efficacy of autologous blood donation in female cabg patients. Due to the small sample size of our investigation, further prospective studies are necessary to answer the question whether patients with low blood volume, body weight and body height scheduled for cabg surgery should be excluded from autologous blood donation.
