AbstractA 41-year-old male patient with well-controlled hypertension underwent a partial nephrectomy under total intravenous anesthesia with propofol, fentanyl and ketamine. To avoid allogeneic blood transfusion, preoperative autologous blood donation (400 g) a week before the surgery and acute normovolemic hemodilution (800 g) after induction of anesthesia were performed. As surgical blood loss was more than 4000 g, blood hemoglobin (Hb) level decreased to 6.4 g.dl-1. However, as intraoperative hemodynamics was relatively stable with no ischemic changes in ECG and arterial blood gas analysis did not show metabolic acidosis, autologous blood transfusion was withheld till hemostasis had been done. After returning the autologous blood, Hb increased to 9.4 g.dl-1. On the 2nd postoperative day, Hb decreased to 7.6 g.dl-1. As the patient's vital signs did not show any severe complications, blood transfusion was not performed. Then, the Hb level increased gradually to 13.9 g.dl-1, 3 month later without allogenic blood transfusion. In addition, any postoperative complications by low Hb level were not recognized so far. This case suggests that combination of autologous transfusion techniques may be effective to avoid allogeneic blood transfusion even against massive hemorrhage. However, to avoid disadvantage of these technique, we should always evaluate preoperative patient conditions.
