[Anesthesia for a patient with red cell aldolase deficiency].

Aldolase deficiency of red blood cell is a rare cause of hereditary hemolytic anemia and now there exists only three patients in the world. We had a 24-year-old man operated on for gallbladder stone secondary to this uncommon disease. He underwent a cholecystectomy under general anesthesia combined with thoracic epidural block, using isoflurane, fentanyl, vecuronium, midazolam and lidocaine. During the surgery serum concentrations of bilirubin, free hemoglobin and LDH showed no change, suggesting a lower incidence of drug-induced hemolysis in the case of aldolase deficiency than in other enzyme deficiency. This fact also provides a useful guide to the choice of anesthetics and related agents. In the postoperative period, however, we found a hemolytic response to fever with a drop in hemoglobin level to 2.5 g.dl-1. Aldolase activity of his red cell is heat labile and an increase in body temperature may aggravate a disturbance in the glycolytic pathway leading to hemolytic crisis. It is thus important to prevent the body temperature from rising when a patient is suffering from hemolytic anemia due to red cell aldolase deficiency.
