Intraoperative autologous transfusion in revision total hip arthroplasty.
The records of ninety-eight patients (100 hips) who had revision total hip arthroplasty were reviewed to evaluate the efficacy of intraoperative autologous transfusion in reducing homologous blood-transfusion requirements. In the fifty hips in the study group, a mean of 685 milliliters of autologous blood, or 47 per cent of the estimated loss of blood, was transfused intraoperatively. During the entire course of hospitalization, the mean of the total homologous blood-transfusion requirements was 795 milliliters in thirty-nine study-group patients, compared with 1160 milliliters in forty-six control-group patients who did not have autologous transfusion. This difference was statistically significant (p less than 0.029). Eleven patients in the study group and four patients in the control group did not receive homologous blood. Over-all, the use of intraoperative autologous transfusion was directly responsible for a 42 per cent reduction in the total amount of homologous blood that was transfused.
