Abstract : Microemboli formed in vivo and platelet aggregates induced in vitro in the blood of patients undergoing cardiac operations were measured with an electronic particle size analyzer. The effects of extracorporeal circulation, surgical trauma and blood filtration on platelet function were assessed. The results demonstrated that membrane oxygenation reduced particulate microembolization and preserved platelet function, but that microembolization resulting from transfusion of stored homologous blood and intraoperatively autotransfused autologous blood persists regardless of the type of oxygenator used.
