Malignant hyperthermia is an inherited disease of skeletal muscle characterized by acute elevations of body temperature. The hyperthermic crisis is triggered by a variety of drugs and by volatile anesthetics or it may occur in response to stress. In this report the authors describe the case of a patient with malignant hyperthermia who underwent emergency aortocoronary bypass surgery for unstable angina. They outline the anesthetic and surgical management for individuals susceptible to hyperthermic crises who require open-heart surgery.

A 56-year old man was admitted for elective mitral valve repair and coronary artery bypass surgery due to mitral valve leakage and unstable angina. After induction of anaesthesia he developed a combined metabolic and respiratory acidosis. Different diagnosis were considered and we decided to treat the patient with dantrolene due to suspicion of malignant hyperthermia (MH). The patient received one dose of dantrolene 2,5 mg/kg during cardiopulmonary bypass (CPB) and a second dose of dantrolene 2,5 mg/kg during weaning from CPB. The first arterial blood gas sample taken in the intensive care unit showed relapse of the acidosis and we administered an infusion of 150 mg dantrolene over 3 hours. The patient gradually recovered without sequel and MH was verified by muscle biopsy testing.
