AbstractTwo cases of malignant hyperthermia with different clinical courses are reported. The patients showed the classical signs of malignant hyperthermia consisting of tachycardia, tachypnoea, ocasional peripheral cyanosis, high body temperature as well as characteristic rise in serum enzymes. In one of the patients the symptoms were recognized early during the operation. The immediate commencement of therapy with ice-cooled. Ringer-Lactate-Solution, Procainmedication, Corticoids as well as physical body cooling favourably influenced the clinical course and the patient survived. In both cases the patients underwent succinylcholine and halothane anaesthesia, but the symptoms of the second patient appeared after the reduction of anaesthesia. In spite of vigorous therapy the hyperpyrexia resulted in heart arrest and death. Morphologically, both patients showed signs of preexistent myopathy with volumetric alterations of the muscle fibres, centralisation of the nuclei and acute muscle fibre necrosis. On the basis of the observed variable course, the various symptom complexes reported in the literature to data are reviewed. A detailed discussion of the "carrier problem" and the available treatment possibilities is also made. Realising that malignant hyperthermia is an inheritable disease, prophylactic measures such as, f.i. the issue of medical certificates to the patient and his relatives are suggested.
