Rhabdomyolysis

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 it can have no symptoms or physical signs.

Diagnosis is confirmed by elevated serum CK level.

Fluid hydration is the mainstay of therapy.

Rhabdomyolysis may result from any traumatic or medical injury to the sarcolemma (the myocyte cell membrane). The subsequent release of intracellular ions, myoglobin, CK, and urates into the circulation results in electrolyte disturbances, disseminated intravascular coagulation (DIC), renal failure, and multi-organ failure. The measurement of serum CK levels at 5 times the upper limit of normal is used as diagnostic criterion.
