[Autologous transfusion--organization and results of preoperative blood donation by heart surgery patients].

This study presents our preoperative autologous blood donation programme that is in use since 1987. 246 patients of cardiothoracic surgery participated in this program. 77% of all patients had preoperative concentrations of haemoglobin above 12g/dl despite frequent donations. 36.5% of patients were transfused exclusively with their own blood products. Reduction of homologous blood transfusion has been achieved with second preoperative plasmaphereses and more restricted indication for blood transfusion. More blood donation could be performed with application of erythropoietin resulting in more frequent preoperative blood donations.

[Comparative study of antibody identification in the gel centrifugation test (ID Microtyping System), solid phase antiglobulin test (Solidscreen Capture R, Ready ID) and tube test].

The gel centrifugation test (ID Microtyping System)--a new method for antibody screening--was compared with solid phase systems (Solidscreen, Capture R, Ready ID) and the conventional tube test. 141 different antibodies were tested and the results were compared. The ID Microtyping System identified 138 (98%) of all antibodies, the tube test 110 (78%), Capture R 86 (61%), Ready ID 79 (56%) and Solidscreen 75 (53%). The results in identification of all antibodies except cold agglutinins (n = 107) were: in the ID Microtyping System 98% (105), tube test 76% (82), Capture R 70% (75), Ready ID 68% (73) and Solidscreen 61% (65).

[Preoperative autologous blood donation].

This presentation shows our experiences with the preoperative autologous blood donation existing since 1987, 246 patients of the cardiothoracic surgery participated in this program. The preoperative concentration of hemoglobin was above 12g/dl 76.8% of the patients despite the frequent donations, 36.5% of the participants could be transfused with their own blood products. Further reduction of homologous blood transfusion could be achieved with a second preoperative plasmapheresis and the donation of erythropoietin.

[The gel centrifugation test in serologic compatibility testing].

The gel centrifugation test is described in compatibility testing. The conventional method was modified resulting in easy handling for technical assistant. 2560 of compatibility testings were performed. 5% of more relevant antibodies could be detected compared with conventional tube test.
