| Abstract: | Different blood saving methods are analyzed in 2000 cardiac surgical patients undergoing coronary and vascular bypass surgery in 1993 to 2000. The basic blood saving methods are as follows: intraoperative autoreinfusion (normovolemic thermodilution), reinfusion of the patient's blood, preoperative autologous plasma donation in combination with aprotinine, aminocapronic acid, etc. An analysis revealed a decrease in homologous blood components intraoperatively. Red blood cell transfusion decreased from 100% in 1993 to 44% in 2000, fresh frozen plasma and platelet transfusions did from 98 to 39% and from 96 to 1%, respectively. Intraoperative homologous blood transfusion could be avoided in 70% of those undergone coronary bypass surgery. |
