[Clinical and laboratory aspects of malignant hyperthermia in children with special reference to creatine kinase isoenzymes (author's transl)].

The clinical and laboratory findings in 4 children with signs of malignant hyperthermia are reported. In all cases an extraordinary elevation of creatine kinase activity in serum was observed. By investigation of the creatine kinase isoenzyme activities we tried to determine the origin of creatine kinase.
