Transfusion of homologous blood components is associated with immunological (incompatibility, alloimmunization, immunosuppression) and infectious risks (hepatitis, cytomegalovirus, HIV and other agents). Endoprosthetic surgery of the hip and knee frequently requires transfusion. Preoperative deposit of autologous blood can reduce homologous transfusion requirements. The simplest method is liquid storage of whole blood. In order to re-examine the efficiency of our present scheme of preoperative deposit, we studied patients scheduled for endoprosthetic surgery with respect to the amount of blood deposited, stimulation of erythropoiesis, and homologous blood requirements at the time of operation. PATIENTS AND METHODS. Sixty-seven consecutive patients (33 men, 34 women) scheduled for endoprosthetic replacement of hip or knee or for revision arthroplasty of the hip were studied. Patients with anemia, coagulopathies, coronary heart disease, severe obstructive or restrictive pulmonary disease, cerebral sclerosis, syncopes and seizures were excluded from preoperative deposit. Patients deposited 450 ml at weekly intervals, with occasionally slightly higher or lower volumes. A patient was temporarily deferred when the hemoglobin concentration prior to donation fell below 11 g/dl. Blood was collected in CPDA-1 buffer. The aim was a deposit of three units. In patients undergoing exchange reoperation of a total hip arthroplasty, intra- and postoperative autotransfusion with a cell separator was employed in addition to preoperative donation. RESULTS. The age of the patients ranged from 43 to 83 years (mean +/- SD: 61.2 +/- 9.1). The differences between men and women with respect to height (172.9 +/- 6.8 vs 160.6 +/- 7.4 cm; p less than or equal to 0.001), weight (75.7 +/- 11.2 vs 69.1 +/- 11.0 kg; p less than or equal to 0.05), calculated blood volume (p less than or equal to 0.001), and erythrocyte volume prior to donation (p less than or equal to 0.001) were significant. A total of 185 units was deposited. Men donated 1350 (450-1970) ml blood (median, range) and women 1260 (340-1450) ml (p less than or equal to 0.01). Hemoglobin concentrations decreased significantly from an average of 14.7 g/dl in men and 13.8 g/dl in women prior to donation to 13.4 g/dl and 12.3 g/dl preoperatively (p less than or equal to 0.0001 for both groups). The donation was not associated with serious complications. For 4 patients the scheduled operation was deferred for a longer term. Forty-six patients (23 men, 23 women) underwent total hip arthroplasty, 12 (4 men, 8 women) exchange of total hip arthroplasty, and 5 (3 men, 2 women) endoprosthetic knee surgery. In total hip arthroplasty men required 0 to 500 ml homologous packed red cells (median=0), women 0 to 1250 ml (median=0;p less than or equal to 0.05). Thirty-nine (69.6%) of the patients, 19 (82.6%) men and 13 (56.5%) women, did not require homologous transfusion.(ABSTRACT TRUNCATED AT 400 WORDS)
