The principles of treatment for acute injury are: first, the patient must be made to lie down and rest is the main focus, if the limb is swollen, the affected limb can be elevated to promote venous return. Second, the patient’s consciousness and the four vital signs must be closely observed, if there is a decrease in blood pressure, it may be acute traumatic, hemorrhagic shock, should be immediately given to open intravenous access, accelerate rehydration to replenish blood volume, in order to correct shock. Third, if bleeding is found in the limb, cotton pads should be given to cover the wound and pressure bandages should be given afterwards to stop the bleeding. If there is an obvious deformity of the limb, it may be a fracture or dislocation, and should be given a splint or brace for external fixation to stabilize the local injured position, and then sent to the hospital as soon as possible. Fourth, if it is a fracture of the spine or cervical vertebrae, you can use some cervical or lumbar circumference to fix the local injury, and then use a spinal plate to carry the patient and send him to the hospital as soon as possible for relevant examination and treatment.
