[Myoglobinuria following anesthesia (author's transl)].

In a 11 1/2 year-old boy, acute myolysis with myoglobinuria followed anesthesia and had a favourable outcome. Biological signs of myolysis, without clinical symptoms seem to be frequent after Halothane-succinylcholine anesthesia. They are even more frequent in children, especially when succinylcholine is repeatedly given during Halothane anesthesia. Patient clinical symptoms (visible myoglobinuria, pain and/or paralysis) are rare and occur chiefly in children with chronic muscular disease, in whom they may be the presenting symptoms.
