crush syndrome refers to a clinical syndrome characterized by limb swelling, necrosis, hyperkalemia, myoglobinuria and acute kidney injury when the muscle-rich parts of the limbs or trunk are squeezed for a long time. The core link of squeeze syndrome is rhabdomyolysis, which causes the contents of muscle cells to leak into extracellular fluid and blood circulation, resulting in a series of complications such as reduced effective circulating blood volume, electrolyte disorder, acute kidney injury and multiple organ dysfunction. Earthquakes, landslides, mine collapses, mudslides, hurricanes, wars, etc. may produce a large number of patients with crush syndrome[1,2,3,4,5]。
