BackgroundAn increasing demand for blood products forces the rationalisation of management and conservation of blood. The aim of the study is to evaluate the possibility of retransfusion of blood conservation and the cost-effectiveness of this procedure when employed in Total Hip Replacement and Total Knee Arthroplasty.Material And MethodsThis prospective cohort study involved two groups of patients. Group I comprised 50 patients who underwent blood retransfusion and in several cases had supplementary allogeneic transfusion. Group II, a control group, consisted of 50 patients who did not receive retransfusion.ResultsThe retransfusion in Group I enabled the recovery of a mean amount of 364.5 ml (± 52.7) of blood in THR patients and 403.8 ml (± 110.7) in TKA patients. Demand for allogeneic blood transfusions in Group I versus Group II was 46% lower in THR patients and 42% lower in TKA patients. The blood recovered for retransfusion is biologically valuable with regard to cellular elements and plasma chemistries. In the costs evaluation, the total savings in Group I were 5,000 PLN.ConclusionRetransfusion of recuperated blood from postoperative drainage tubing is a simple and safe method that provides clinical and cost-effectiveness advantages.
