As the saying goes, a car accident is as fierce as a tiger. In 1992, 56,300 people were killed and 2.5 million injured in traffic accidents in the United States, greatly exceeding the number of casualties in the 10-year war against Vietnam. The incidence of traffic accidents in China is also rising rapidly, with more than 200,000 casualties each year, which is equivalent to the destruction of a not-so-small city. Among the emergencies in which the city’s emergency center is involved, car accidents are always in the first place. From the situation of patients admitted to our department in recent years, the injuries caused by car accidents are increasing year by year, and the injuries are mostly compound injuries. These are not boring information, the bloody facts tell us that we should pay attention to the on-site emergency treatment of car accidents, i.e. pre-hospital treatment, in order to reduce casualties. In addition to ensuring the safety of the injured, don’t forget to contact 120 and report to the traffic department in case of other car accidents. The injured person needs to be taken to the hospital regardless of the degree of injury at the time of the accident. The injuries are different from the accident scene and the position of the injured person, therefore, treatment should be provided on the spot according to the specific injuries. In order to ensure the safety of the injured, in principle, try not to move the injured. However, if the accident site is too dangerous, get help and carefully move the injured person to a safe place. Prevent other car accidents from occurring. Use warning signs with triangles to alert oncoming traffic from behind. Car accidents can cause a variety of injuries of varying degrees of severity. The most important thing is to respond calmly. The first thing to check is for consciousness and the presence or absence of breathing and pulse. Never twist the injured person’s body, because car accidents often injure the neck bones and nerves, and twisting the injured person’s body is a fatal action. In addition to checking for consciousness, breathing, and pulse, it is more important to check for heavy bleeding. Arterial bleeding, where blood spurts out from the wound in large quantities, or venous bleeding, where blood drips out in large quantities, may cause life-threatening injuries. In this case, it is necessary to stop the bleeding as soon as possible. Use a clean handkerchief to apply pressure to the wound and use direct pressure to prevent hemorrhage. Shock is easily caused by hemorrhage, so it is necessary to administer shock treatment. If you are conscious and not bleeding profusely, you can be rescued according to the injury before the ambulance arrives. The most common case is when the driver is hit by the steering wheel or a deformed cab and is trapped in it. At this point in the cab doors and windows after prying open, should first give the casualty on the neck brace, such as no neck brace, can first use cardboard or thick plastic paper to fix the neck, so as to avoid cervical spine dislocation or injury, while a board can be inserted into the back of the casualty, and then fixed with bandages or cloth, the casualty will be pulled out of the cab, which is conducive to transport the casualty out, but also to prevent the possible cause or aggravation of spinal cord injury. In the United States and some other developed countries, the injured due to car accidents, this first aid action has become a “rule”. Doing so can greatly increase the rate of treatment. The casualty who bounced off the sitting position, can not just lift and hold, because this casualty’s spinal cord is likely to have been damaged, a moment of improper handling, will aggravate the existing spinal cord injury, or even lead to its rupture, from which the casualty will be paralyzed for life! The correct method is: turn the casualty as a whole to a lying position, on the neck brace, by 3-4 people to standardize the action, the pace of its lift, one of them is responsible for protecting its head, so as not to head and neck forward, backward or rotation. When lifting, one person can shout the password, the first-aiders lift the casualty at the same time, move to the stretcher or board, fixed with bandages and then carry. How to carry a casualty if there is only one person at the scene? At this time, the first-aider should be close behind the casualty, arms through the casualty’s armpits, grab his injured arm and upper body, gently lift the casualty, and then carefully drag backward. When dragging, ensure that the casualty’s head, neck and chest are located in a straight line, so that his or her head rests on the first-aider’s shoulder or face, taking care to avoid the casualty’s head from flexing, side-bending or backward, and then place him or her flat on his or her back on a wooden board for fixation. After placement, the trauma of the casualty should be handled accordingly: for bleeding limbs, a pressure bandage or tourniquet can be given to stop the bleeding, and for fractured limbs, a simple splint should be used to fix them. If you can’t find a splint, take a village in place, use a branch, board, cardboard or a magazine rolled into strips instead to fix the fracture, or tie the fractured lower limb to the key side of the limb, if an open pneumothorax has formed, it must be sealed and bandaged immediately. For those who have gone into shock, take a supine or stable lateral position and elevate the lower limb to increase the amount of blood returned to the heart and ensure blood supply to the brain. Also pay attention to keep warm. In addition, the casualty who has been unconscious, due to the back of the tongue often block the airway caused by asphyxia, at this time can be used to open the airway by tilting the head to the side, and make the casualty head slightly tilted to the side, in order to facilitate the exclusion of secretions, blood, mucus and other foreign bodies in the oral and nasal cavities. At the same time, remove sharp knives, metal coins, keys and other objects from the casualty to avoid crushing injuries. In principle, it is forbidden to take any beverage or tea to the casualty. Because, most of the casualties must be surgical treatment, eating is bound to increase the difficulty of surgery. In addition, because the casualties often vomit, once the food is inhaled into the respiratory tract, it will certainly aggravate the injury. After the above initial treatment, the casualty can be under the supervision of medical personnel. Quickly to the hospital emergency. The speed of the car on the way should be slow, so as not to aggravate the injury due to bumps. If the first-line hospital has difficulty in treating the patient can be sent to a higher-level hospital for treatment after the patient’s condition is stabilized.
