Abstract

Mortality and morbidity of malignant hyperthermia has decreased markedly by the avoidance of succinylcholine, and the earlier detection and introduction of dantrolene. We report a fourteen-year-old boy who developed malignant hyperthermia during general anesthesia. He showed the earlier clinical signs, such as elevation of end-tidal CO2, tachycardia, and hypertension. After prompt administration of dantrolene, operation was continued with profopol and midazolam. Rhabdomyolysis and myoglobinuria followed, and were managed by hydration and alkalinization of urine. Azotemia did not occur, and he was discharged without any sequelae on the 10th postoperative day.
