A Clinical Study to Investigate if Transfusion of Patients Own Shed Blood Improves the Immunological Status in Comparison to Transfusion of Donor Blood ("Bank Blood")
An Open , Prospective, Randomized, Parallel Group Study to Investigate Whether Postoperatively Collected and Transfused Autologous Whole Blood Improves the Immunological Status in Comparison to Allogenic Blood Transfusion in Patients Undergoing Total Knee Replacement
The primary objective of the study is to compare the immunological status after either autologous blood transfusion as administered by Bellovac® ABT or allogenic blood transfusion, with regards to change in Natural Killer (NK) cell frequency in patients undergoing total knee replacement.
