| Outline of Final Research Achievements |
Under cardiac surgery with cardiopulmonary bypass, an autologous platelet product was prepared using the Haemonetics Component Collection System(R) by drawing blood from the cardiopulmonary circuit immediately after cardiopulmonary bypass was initiated. The blood sample ware taken at three points for examination, A: beginning of surgery, B: immediately after heparin reversal with protamine following discontinuation of cardiopulmonary bypass, C: after the collected autologous platelet product was returned to the patient. Platelet count and platelet aggregation ability were compared.
Autologous platelets can be collected by drawing blood from the cardiopulmonary bypass circuit, and this method maintains effective aggregation ability upon returning the platelets to the patient.
