We experienced a malignant hyperthermia in 24-year-old male with sevoflurane during the mandibular prognathism surgery. The malignant hyperthermia emerged 150 minutes after induction of general anesthesia using propofol, rocuronium, sevoflurane, N2O and O2. Sevoflurane has been reported that it can induce delayed onset of malignant hyperthermia under absence of succinylcholine. The prognosis of malignant hyperthermia is determined by early recognition, vigorous treatment and the time of dantrolene injection. In our case, when we suspected episode, all anesthetics were stopped and dantrolene injection was immediately given intravenously. The patient recovered normal temperature and consciousness without any complication.
Key Words: dantrolene; malignant hyperthermia; sevoflurane
