Opening or suction wound of the chest should be closed immediately, otherwise it can die of severe hypoxia. Serious bleeding pressure bandage, tourniquet and anti-shock trousers control. Apply a tourniquet once every 1 hour relaxing, so as to avoid long periods of ischemia causes tissue necrosis. Wounded because of bleeding, shock, can enter the balanced solution, such as Lin's lactate solution to correct low blood volume. Fixed to fracture or severe soft tissue injury. Trauma handling through a variety of rescue, the wounded brought to or remained stable, and then transported. Course should pay attention to safety, balance, fast delivery.
