Malignant Hyperthermia and Electroconvulsive Therapy.
A 30-year-old man with a personal and family history of malignant hyperthermia and a 7-year history of psychiatric illness unresponsive to various psychotropic medications benefitted from electroconvulsive therapy given in combination with clozapine. Volatile inhalation anesthetics and a depolarizing muscle relaxant (succinylcholine) were assiduously avoided. Dantrolene was administered intravenously before the first treatment but was not used for the remainder of the treatments. Anesthesia was induced with methohexital and atracurium. The treatment course was uneventful.
