[A case of abortive malignant hyperthermia during funnel chest surgery]

We experienced a case of abortive malignant hyperthermia during funnel chest surgery. Although a 5-year-old boy had muscle rigidity after the intravenous injection of succinylcholine chloride, the tracheal intubation was easy. The boy had high body temperature, metabolic acidosis, hyperkalemia and myoglobinuria during nitrous oxide-oxygen-sevoflurane anesthesia. We immediately came to the diagnosis of abortive malignant hyperthermia, gave intravenous injection of dantrolene sodium and started body surface cooling. Postoperative course was uneventful. It is necessary to pay a particular attention to possible malignant hyperthermia in patients with funnel chest surgery.
