Crush injury and crush syndrome.

Crush injury is caused by continuous prolonged pressure on the limbs. It is found in patients extricated after being trapped for at least 4 hours. The main injury is to the muscles of the limbs. Treatment should be conservative and fasciotomy should be avoided. If fasciotomy is performed, it should be followed by radical debridement of the injured muscle in an attempt to avoid infection of the injured limb. Infection endangers the patient's life and is the main cause of morbidity and mortality today. The outcome of conservative local treatment of crush injury is much superior to that of operative treatment. The pathophysiology of crush injury is not fully understood and no good animal model is known. Crush syndrome, which is the general manifestation of crush injury, is better understood. If not prevented, it will lead to acute renal failure. A method for preventing acute renal failure is discussed and a protocol is described. There is no doubt that prevention of acute renal failure is the goal in the treatment of crush syndrome and can be achieved.
