This retrospective study examined the impact of autologous blood transfusion using the acute normovolemic hemodilution (ANH) technique in 59 patients undergoing open heart procedures. Patients were divided into two groups: one receiving autologous transfusion and the other not. While patients in the autologous group had higher preoperative hemoglobin levels, they also experienced a greater postoperative drop in hemoglobin. The requirement for allogeneic blood products was slightly lower in the autologous group but not statistically significant. No major transfusion reactions were reported, and overall complication rates and hospital stays were similar between groups. The findings suggest that autologous transfusion using ANH is safe but did not show a clear advantage over standard care in this cohort.
