Outcomes and biochemical parameters following cardiac surgery: effects of transfusion of residual blood using centrifugation and multiple-pass hemoconcentration

This article compares 2 methods of residual blood treatment after cardiopulmonary bypass. Multipass hemoconcentration led to higher concentrations of platelets and fibrinogen when compared with centrifugation. Clinical outcomes – weight gain, use of vaso-active agents – were reduced in the hemoconcentration group. Further investigation into methods of treatment of residual blood is warranted.
