[Blood transfusion and reducing the need for blood in heart transplantation].
Viral infections transmitted by the donor organ or by blood and blood products are severe complications in heart transplantation. The use of blood and blood saving management is evaluated in 57 consecutive orthotopic heart transplantations. Indication was cardiomyopathy in 63%, coronary artery disease in 30%, valve disease in 5%, congenital in 5%, arrhythmia in 5% and primary cardiac malignancy in 2%. Previous open heart surgery was performed in 32%, and 81% had anticoagulation, with a mean quick value of 0.28 +/- 0.13. The total use of blood and blood products was 1151 units and was distributed as follows: whole blood and packed cells 41%, platelets 17%, fresh frozen plasma (FFP) and coagulation factors 36%, albumine 7%. Anticoagulated recipients received more FFP and factors, 7.9 +/- 5.7 U vs. 4.4 +/- 4.8 U. In the reoperation group 78% vs. 22% (p less than 0.001) in the primary operation group received platelets. Hemodilution to hematocrit 0.24 instead of 0.30 lead to a decrease of red cell transfusions per patient from 12.3 +/- 6.7 U to 6.3 +/- 7.4 U (p less than 0.001) and the percentage of patients receiving red cells was reduced from 100% to 82%. Intraoperative hemofiltration was performed in 49% (mean filtration volume was 1652 +/- 910 ml). No differences in the amount of blood and blood products could be shown. Heart transplantation is an operation with a high need for blood and blood products. Reoperation and anticoagulation are predictors for a higher use of platelets, FFP and coagulation factors. Hemodilution reduces the use of red cells, whereas intraoperative hemofiltration has no influence on the use of blood.
