A study by the American College of Surgeons (ACS) Trauma Section shows that trauma is the leading cause of death before the age of 40, and the economic damage to society caused by hospitalization and loss of labor can reach $100 billion annually. The economic damage to society from hospitalization and loss of labor can reach $100 billion annually. According to Chinese medicine, when the human body is injured by fall or accident, under the action of the cause, it leads to the dysfunction of internal organs and disorder of qi, blood and fluid, resulting in the damage of yin, blood and fluid, followed by the loss of yang and yin or yin and yang, and the imbalance of yin and yang becomes critical illness. Fractures and bruises and sprains belong to the categories of bone injuries and tendon injuries in Chinese medicine, and although the treatment methods are different, one should try to avoid taking the condition lightly as it is impossible to separate them distinctly in the immediate treatment of acute injuries. Simple and effective immediate treatment at the scene of trauma can help maximize the protection of the affected limb, avoid further injury, and buy valuable time for subsequent treatment, especially for saving lives, and his role is irreplaceable. The immediate treatment of fractures, bruises and sprains is so important that it can be summarized in the following three steps: 1, to save lives, the purpose of immediate treatment is to “keep people to cure”. The two keys to life-threatening trauma are bleeding and respiratory blockage, so you should try to clear the foreign body in the mouth and nose cavity to keep the respiratory tract open, and for the casualty who has stopped breathing, you should immediately take the method of artificial respiration to help him restore the normal rhythm of breathing. When there is a lot of bleeding, the majority of pressure bandages can be used to stop bleeding, large blood vessels bleeding, pressure bandages can not stop bleeding, can be used in situ some elastic rubber tube and other things as a tourniquet to stop bleeding, and should record the time on the tourniquet, wound selection site that the cleanest cloth bandage to reduce recontamination, bandage should be elevated injured limbs, take the head and trunk elevated 20 ° ~ 30 °; lower limbs elevated 15 ° ~ 20 ° position, to increase the return of 20 ° position to increase the amount of blood return and reduce the symptoms of shock. During the whole process of treatment, attention should be paid to the insulation of the injured person and minimize moving. 2, the treatment of fractures, proper fixation is the basic principle of dealing with fractures. All suspected fractures should be treated as fractures. For closed fractures, it is not necessary to remove the clothing and footwear of the injured limb for immediate treatment to avoid excessive movement of the affected limb and increase the pain. If the swelling of the injured limb is severe, scissors can be used to cut open the sleeve and leg of the injured limb to reduce the compression. When the fracture has obvious deformity and there is a risk of penetrating soft tissues or injuring nearby important blood vessels and nerves, the injured limb can be properly traction to make it straight and then fixed. Fixation can be done locally with wooden boards, sticks, branches, etc. or with special splints. If there is no available material, the upper limb fracture can be fixed to the chest and the lower limb fracture can be fixed by tying the injured limb to the contralateral healthy limb. If the fracture is open and the fracture end has been poked out of the wound and is contaminated, and no important blood vessels or nerves are compressed, the fracture should not be repositioned to avoid bringing the contamination deeper into the wound. The fracture should be sent to the hospital for repositioning after invasive treatment. If the fracture end slips into the wound on its own when dressing, it should be recorded for further treatment during debridement. 3.Transfer the injured person quickly. After the initial immediate treatment and proper fixation, the injured person should be transferred to the nearest hospital for treatment as soon as possible. When a fracture of the spine is suspected, the way of transport from the scene of injury to the hospital is crucial. The correct method is to use a stretcher, wooden board or door board to transport the casualty with both lower limbs straightened and the board placed on the side of the casualty, and three people use their hands to hold the casualty flat to the board; or two or three people use the rolling method to keep the casualty straight and roll the casualty to the board as a whole. This can avoid aggravating the injury to the spinal cord. Because of the various manifestations of the injury, it is impossible to elaborate one by one, the above is only some immediate treatment principles, in the specific operation process may have many flexible changes, but as long as you keep in mind that “life first, do not increase the injury”. I believe that the immediate treatment of fractures, bruises and sprains is still relatively easy to do.
