title: Rhabdomyolysis.
abstract: Rhabdomyolysis is a condition caused by skeletal muscle injury and release of muscle cell contents into the circulation. It may result in myoglobinuria, the filtration of myoglobin into the urine, and is often associated with acute renal failure (ARF). Rhabdomyolysis may complicate many disease states. In some, such as crush injury, muscle injury is obvious; in others, such as drug overdose, it may never be apparent. It may occur in the setting of an altered mental status, and even in the conscious patient, it may occur with minimal symptoms or physical findings. Therefore, diagnosis requires a high level of suspicion and appropriate sensitivity to abnormal laboratory values. Many insults can precipitate rhabdomyolysis and myoglobinuria. Disruption of the muscle cell membrane may result from a direct mechanical or toxic insult to the membrane or an inability to maintain ionic gradients across the membrane (as in ischemia or extreme exertion). This article reviews the etiology, pathogenesis, clinical features, complications, and management of rhabdomyolysis, particularly crush injuries in the setting of a major disaster.
