The Immunomodulation Effect of Blood Transfusion in Operative Spine Surgery Patients
The purpose of this study is to investigate the effect of transfusion of allogeneic (homologous) red cells on the immunologic parameters such as T-cells as well as natural killer cell count/function, various interleukins, TNF alpha and other immunologic relevant parameters on postoperative day 1,3 and 5-7 in patients undergoing spine surgery.
