Squeeze injury (squeeze) refers to the compression of an extremity or other part of the body, resulting in muscle swelling and/or neurological disorders in the affected body part. These two types of injuries often coexist, causing extensive damage to soft tissues, blood vessels, nerves, bone and other tissues and organs of the body. Crush injuries often injure internal organs, resulting in stomach bleeding, lung and liver and spleen rupture. More serious crush injuries are larger and heavier objects squeezing the body, so that the human tissue and organs occur extensive injuries, such as earth, stone burial injuries. Crush injury symptoms cause: 1, hands, feet by bricks, stones, doors, windows, machines or vehicles, such as violent crush injury; 2, explosion impact on the body injury; 3, various reasons for the collapse of buried body caused by injury; 4, the body itself crowding, trampling caused by injury. Typical body parts involved include the lower extremities, upper extremities and torso. According to the different parts of the crush injury and the degree of severity, the treatment method is also different.
