ABSTRACT
In a randomized study, the effect of whole blood transfusion versus packed RBCs transfusion on CD4+:CD8+ ratio, the levels of soluble interleukin 2 receptor [sIL-2R] and interleukin IL-6 as well as on the development of the postoperative wound infection and intra-abdominal abscess, was assessed in 45 patients undergoing elective colorectal surgery. The patients were subdivided into three groups: Group A included 13 patients who were randomly selected received whole blood transfusion when blood transfusion was indicated, group B included 13 patients who were randomly selected received packed RBCs when blood transfusion was indicated and group C included 19 patients who did not receive any blood transfusion. The samples were obtained prior operation and 3, 7 and 30 days postoperatively. The study demonstrated that transfusion with whole blood in elective colorectal surgery was followed by a significant depression in immunocompetence and this depression is attenuated by the use of packed RBCs transfusion
