The need to reduce the risk of infection and the costs of homologous blood transfusion in elective orthopedic surgery has led to the use of postoperative reinfusion of autologous shed blood. These techniques entail the collection and reinfusion of the patient’s blood with dual-filter systems without heparinization or washing the blood. One such system is the Ortho P.A.S. (Polimed) which permits postoperative collection of shed blood from surgical wound drains and its reinfusion after being filtered. The system consists of a disposable blood collection and reinfusion kit and a multiuse aspirator. The blood passes through a closed circuit, thus ensuring its sterility for reinfusion and protection of nursing staff. The unit is also equipped with a dual filter system in which the blood is filtered inside the collection reservoir and then again with a Goccia filter during reinfusion. Lipid particles are aspirated by a supernant separator. In the author’s experience, the system was found to be safe and easy to use. It offers the advantages of sterility and safety for patients and health workers, is well tolerated, and provides good hemodynamic stability. The system considerably reduces the need for homologous blood transfusion. The price of acquisition and maintenance costs are reasonable.
