Closed-loop postoperative autotransfusion

Postoperative closed-loop autologous transfusion of blood is now in clinical use in the cardiac surgical intensive care unit of the authors´ institution. The automated system requires minimal human intervention. The authors relate the need for autotransmission and distinguish among the different types. A description is given of the apparatus, software algorithm, and procedures that deliver postoperative autotransfusion with real-time feedback of relevant patient parameters. Postoperative closed-loop autotransfusion has proved to be a process with clinical benefits that requires limited time from the patient-care personnel. It increases patient safety and is cost-effective.<>
