title: [Rhabdomyolysis].
abstract: Rhabdomyolysis is a severe clinical symptom of variable etiology. Acquired factors of exogenous origin such as traumata and endogenous metabolic disturbances have to be separated from hereditary disease as causative mechanism. Most frequently, exertional stress during hyperthermia, traumatic damage or ethanol abuse are observed. Almost independent of the diverse initial events, the pathogenesis follows a common final pathway with intracellular calcium accumulation and ATP depletion. Clinical symptoms vary. Seldom, the classical triad of muscle pain, weakness, and dark urine is observed. Recurrent episodes should raise suspicion of an inherited disorder. Severe complications are hypovolemia, electrolyte disorders with hyperkalemia and hypocalcemia resulting in life threatening arrhythmias, a compartment syndrome, disseminated intravascular coagulation and acute renal failure, which is frequently oligo-anuric. In combination with often severe underlying disease, renal failure causes death in 1/5 of the patients. The diagnosis is made with the determination of serum creatine kinase and the myoglobin levels in plasma and urine. Therapeutic options are to correct the hypovolemia with sufficient fluid supply, the prevention of oliguria using loop diuretics, alkalinization of the urine, normalization of serum electrolytes with reduction of hyperkaemia, and decompression of compartment syndromes. An underlying disease should be evaluated to initiate specific therapeutical and preventative steps. Avoiding pre-disposing factors by identifying the mechanisms of disease will reduce the occurrence of rhabdomyolysis with its still high mortality.
