Malignant hyperthermia is a rare disorder that can occur in patients who are sensitive to certain agents used in general anesthesia. The treatment of malignant hyperthermia has not changed over the years, but prevention strategies have evolved. These strategies include an increased emphasis on how patients are managed prior to a surgical procedure, on the selection of the particular anesthetic agent, and on postoperative vigilance. ⋯ All local anesthetics--including lidocaine, which had been previously contraindicated--are now considered to be safe for use in patients who are susceptible to malignant hyperthermia. In this article, we review the prevention, diagnosis, and management of malignant hyperthermia. We also report our experience in anesthetizing a patient who had a history of malignant hyperthermia--a case that illustrates the uncertainty that can complicate the management of such patients.
