Rhabdomyolysis is a condition in which damaged skeletal muscle tissue breaks down rapidly. Breakdown products of damaged muscle cells are released into the bloodstream; some of these, such as the protein myoglobin, are harmful to the kidneys and may lead to kidney failure. The severity of the symptoms, which may include muscle pains, vomiting and confusion, depends on the extent of muscle damage and whether kidney failure develops. The muscle damage may be caused by physical factors (e.g. crush injury, strenuous exercise), medications, drug abuse, and infections. Some people have a hereditary muscle condition that increases the risk of rhabdomyolysis. The diagnosis is usually made with blood tests and urinalysis (urine showing characteristic discolouration pictured). The mainstay of treatment is generous quantities of intravenous fluids, but may include dialysis or hemofiltration in more severe cases. Rhabdomyolysis and its complications are significant problems for those injured in disasters such as earthquakes and bombings. Relief efforts in areas struck by earthquakes often include medical teams with the skills and equipment to treat survivors with rhabdomyolysis. (more...)
