[A case of malignant hyperthermia unrelated to anaesthesia (author's transl)].

Narcots and muscle relaxants are proven causes of malignant hyperthermia. Alcohol and a large number of drugs are capable of inducing myopathic changes which resemble malignant hyperthermia. The case of a 47-year-old man is reported who presented with the clinical symptoms of maligant hyperthermia. The similarity in the course of the disturbance, the clinical and chemical findings and the changes in the morphological features of the muscle suggested that the abnormally high body temperature had been induced by psychotropic durgs in a pre-disposed patient with an history of chronic alcoholism.
