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 […]

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. […]
