A new technique for hemodilution, preparation of autologous platelet-rich plasma and intraoperative blood salvage in cardiac surgery.

We have developed a new system for the production of autologous platelet-rich plasma and red blood cell concentrates to be used in autologous transfusion support of cardiac surgery patients. In 15 operations no homologous blood products were required. Costs were diminished since with the same harness it was possible to carry out the intraoperative blood salvage and concentrate the erythrocytes contained in the oxygenator and its lines. Indirect costs were also reduced since no infective complication was observed due to homologous blood products.
