End result of any disease process that causes muscle cell (myocyte) lysis.
May have an obvious presentation, such as traumatic "crush" injury, or may be insidious, requiring a high clinical index of suspicion.
Muscular pain or discomfort is common, but rhabdomyolysis can have no symptoms or physical signs.
Diagnosis is confirmed by elevated serum creatine kinase level.
Fluid hydration is the mainstay of therapy.
Rhabdomyolysis may result from any traumatic or medical injury to the sarcolemma (the myocyte cell membrane) of the skeletal muscle cells. The subsequent release of intracellular ions, myoglobin, creatine kinase (CK), and urates into the circulation results in electrolyte disturbances, acidemia, disseminated intravascular coagulation, renal failure, and multiorgan failure. The measurement of serum CK levels at more than 5 times the upper limit of normal is used as diagnostic criterion.
