Suxamethonium-induced rhabdomyolysis in a healthy middle-aged man.
A 43-year-old man developed rhabdomyolysis after uvulo- palatopharyngoplasty. After induction with thiopentone and suxamethonium the anesthesia was maintained with halothane. The patient responded to treatment and made an uneventful recovery. In earlier reports of rhabdomyolysis after general anaesthesia with halothane and suxamethonium almost all the patients had malignant hyperthermia (MH) or muscular dystrophy. About 50% of malignant hyperthermia patients carry a mutation in the RYR1 gene. Our patient did not have mutations in the four MH-associated genes tested, but the total amount of different mutations is by now about twenty. Therefore, despite these negative tests rhabdomyolysis may be a sign of subclinical malignant hyperthermia which cannot be ruled out by our investigations. This rare case of rhabdomyolysis in a healthy man suggests careful monitoring of the patient when-ever suxamethonium is used.
