There is a close relationship between inflammation and coagulation response. Inflammation and coagulation are activated simultaneously during cardiopulmonary bypass, which induce postperfusion syndrome. Leukocyte depletion filter can inhibit inflammation by reducing neutrophils in circulation. But, its effects on blood conservation are limited. Aprotinin is a serine protease inhibitor, and can prevent postoperative bleeding by anti-fibrinolysis and protection of platelet function. But its effects on anti-inflammation and protection of organs are subjected to be doubted. The combination of leukocyte depletion filter and aprotinin can inhibit inflammation as well as regulate coagulation, and may exert a good protective action during cardiopulmonary bypass.
