Autologous Blood Predeposit before Surgery of Hip and Knee

We retrospectively studied autologous blood transfusion in 65 cases of hip and knee arthroplasty. The cases consisted of 10 males and 45 females whose age ranged from 34 to 81, with an average age of 61.3 years.Autologous blood was preserved by liquid, and in 35 cases, Erythropoietin (EPO) was intravenously administrated 3 times a week.We have been performing autologous blood transfusion on patients treated with hip and knee arthroplasty since 1990, and the method allows us to avoid homologous transfusion in 88.9% of our patients.
