Fever and autologous blood retransfusion after total knee arthroplasty: a prospective study of 40 autotransfusion events in 21 patients.
The authors report a postoperative increase in body temperature by 2C within 12 h and 1C within 2 h after autotransfusion in all of 21 patients receiving about 1000 mL of drainage blood (with unspecified content of RBC), and none of the patients returning to normal temperature within the observation period (first two postoperative days).

Influence of acid-citrate-dextrose anticoagulant on blood quality in retransfusion systems after total knee arthroplasty.
The authors propose to refrain from ACD anticoagulation in orthopedic postoperative autotransfusion. Their conclusion is not convincing. Products of activation of coagulation and fibrinolysis were not tested, although the main reason for anticoagulation is to decrease those dangerous contaminants. How can the authors justify to a patient with relevant blood loss the failure of the […]
This is a helpful report to design an autologous transfusion strategy. The conclusion is that one must extend blood salvage to the postoperative period or combine intraoperative blood salvage with predonations, as has been described. – E. Hansen.
Time-related changes of collected shed blood in autologous retransfusion after total knee arthroplasty.
The prolonged collection of drained blood is problematic due the risk of bacterial contamination and to the exponential proliferation of bacteria at room temperature. Some countries prohibit collection exceeding 6 hours by regulations or even by law (Germany). The reported analysis cannot reflect “blood quality,” since parameters for humoral and cellular activation were not included. […]
