Injury due to external compression of the body From Wikipedia, the free encyclopedia
A crush injury is injury by an object that causes compression of the body.[1][2] This form of injury is rare in normal civilian practice, but common following a natural disaster.[3] Other causes include industrial accidents, road traffic collisions, building collapse, accidents involving heavy plant, disaster relief or terrorist incidents.[4]

Crush syndrome is a systemic result of skeletal muscle injury and breakdown and subsequent release of cell contents.[4] The severity of crush syndrome is dependent on the duration and magnitude of the crush injury as well as the bulk of muscle affected. It can result from both short-duration, high-magnitude injuries (such as being crushed by a building) or from low-magnitude, long-duration injuries such as coma or drug-induced immobility.[4]
Early fluid resuscitation reduces the risk of kidney failure, reduces the severity of hyperkalaemia and may improve outcomes in isolated crush injury.[4]
For casualties with isolated crush injury who are haemodynamically stable, large-volume crystalloid fluid resuscitation reduces the severity of and reduces the risk of acute kidney injury.[5]
