1, the examination of the classification of injuries: road traffic accidents caused by the complexity of injuries, both mechanical injuries, but also falls, burns, etc., the examination of the classification of injuries is to distinguish between the priorities of the injured, so that the critical and have the hope of saving the life of the priority to get rescue, so that the lightly injured people to be properly dealt with. Classification should be combined with the cause of the accident, the posture of the injured and the location of the comprehensive analysis and judgment. Blood pressure, pulse, respiration and other vital signs of changes and the presence of hemorrhage, coma, asphyxia, craniocerebral injuries, limb severance injuries, etc. is an important basis for judging the condition of the injury. Particular attention should be paid to those inactive and no moaning call of the injured, is likely to be seriously injured, and those who screamed and shouted, strong demand for rescue is not necessarily seriously injured. Accident scene inspection and classification of injuries, interference factors, inspection and classification of injuries must remain calm, exclude interference, avoid haste, quickly and correctly do the classification work. Baicheng City Hospital Orthopedics Zhao Weigang 2, the scene of first aid: (1) trauma bleeding – road traffic accidents, trauma bleeding is the most common deep tissue bleeding, more dressings are used to stop bleeding by filling with pressure bandages. Jet-like bleeding, the use of clamping hemostasis, ligation of blood vessels when possible, bleeding of the limbs can use a tourniquet to temporarily stop bleeding. Blunt blow to the human body caused by internal bleeding without wounds is more difficult to judge, in the event that the casualty’s expression of indifference, pallor, cold extremities, unconsciousness and other signs and symptoms, according to the internal hemorrhage injuries referred to the hospital. (2) Respiratory tract obstruction–When the maxillofacial neck is injured, the clot, broken bone fragments, broken teeth and so on at the upper end of the respiratory tract after the injury can enter the respiratory tract, which is most likely to cause respiratory tract obstruction and jeopardize the lives of those who are conscious; if the person with impaired consciousness, coughing and swallowing movement disappears, the blood and vomitus can enter the respiratory tract by mistake and cause obstruction. When the jawbone is fractured, the soft palate may droop, or the fracture piece is displaced, so that the root of the tongue falls back, blocking the pharyngeal cavity, causing asphyxiation. First aid to make the casualty semi-recumbent position, head to the side, loosen the neck buckle, with the hand to remove the oropharyngeal foreign body, or suck out the oral blood clots and secretions. Use twigs, chopsticks or forceps to lift the maxilla and soft palate through the molars. If the tongue falls back and affects breathing, try to pull the tongue out of the mouth and immobilize it. The most effective way to relieve asphyxia is cricothyroid puncture or tracheotomy. (3) Fractures of the extremities – Bone and joint injuries of the extremities should be immobilized at the scene. Fixation material is preferably standard splints, can also be taken from local materials, but also the fracture of the upper limb fixed in the torso, the lower limb fixed in the opposite side of the healthy limbs. On-site immobilization, do not excessively pull the injured limb, do not require correct alignment of the broken end. (4) spinal injury – collision or rollover, the car occupants were hit, extrusion and distortion of the body, excessive flexion of the spine or direct external forces, resulting in dislocation or fracture, located in the spinal canal of the spinal cord may also be injured. If spinal cord injury occurs, try not to make the spine twisted or force when rescuing, the key is to carry the correct. (5) limb severance – at the scene of the accident, the proximal end of the severed limb ligated blood vessels to stop bleeding, bandage the stump, the severance of the more intact part of the clean bag wrapped in cloth, and quickly with the casualty sent to the hospital. Chest injuries – If the broken end of a rib fracture is displaced inward, it may puncture the pleura and lungs, causing pneumothorax and hemothorax. Do not move too much or touch too hard when rescuing; when there is tension pneumothorax. Place a one-way drainage tube to relieve the pressure in the chest cavity; when the lung, pleura and chest wall are injured, an open pneumothorax is formed, and the injury is serious, and a closed bandage must be carried out immediately. (6) abdominal injuries – open abdominal injuries easy to cause visceral prolapse, rescue remember not to send the prolapsed viscera back to the abdominal cavity, so as not to aggravate abdominal infection. 3, the casualty transfer: (1) transfer timing – in principle, the traffic accident casualty quickly transferred to the hospital, such as transfer tools are insufficient, should be given priority to the transfer of serious injuries. It is worth noting that some of the injured are not yet stabilized, such as asphyxia has not been lifted, dyspnea and shock has not been relieved, and those who estimate that accidents may occur on the way of transfer, do not immediately transfer, should be given the necessary emergency treatment at the scene before transfer. (2) Transfer position – the unconscious casualty to take the lateral position, if accompanied by other injuries, when necessary, prone (supine) can also be, but should make the injured head to one side, so as to avoid vomiting stomach contents accidentally inhaled into the lungs or obstructed trachea. Spinal injuries should be prone on a hardboard stretcher. If transferred in the supine position, a protective cushion should be placed on the chest and lumbar region to keep the lumbar region in a hyperextended position. In chest injuries, the patient should be placed in a semi-recumbent position, and those with respiratory distress should be placed in a supine position with the head tilted to one side. Abdominal injuries are treated in the supine position with the head tilted to one side. For head injuries or suspected heart disease, stroke and other complications, do not take the traditional head-low-feet-high shock position. (3) transfer tools and rescue on the way – ambulance speed, traveling smoothly, should be the first choice, and each vehicle should be equipped with health personnel, closely observe the changes in the condition, take measures at any time. In the process of transferring the injured, attention should be paid to the injured to cause completely avoidable secondary injury. For traffic accidents occurring in remote areas with long-distance helicopters to implement medical care. Baicheng City Hospital Emergency Telephone 0436-5088120 0436-96999 0436-3322222
