China is the most populous country in the world, and the number of spinal injuries caused by falls, car accidents, workplace injuries, sports, etc. is increasing every year. Moreover, when an accidental spinal cord injury occurs, people should know some first aid methods to avoid causing “secondary injury” to it. Secondary spinal cord injury is a serious danger to patients, and its prevention is crucial. Accident site spinal cord secondary injury awareness rate is low, there are spinal cord injury patient survey analysis shows that in the accident site, more than 80% of patients and surrounding people do not understand the knowledge of spinal cord secondary injury, the implementation of on-site protection accounted for only 41.5%. The data show that the knowledge of secondary spinal cord injury is low among the public, and the knowledge of self-help at the accident site is relatively lacking. Correct self-help before hospitalization is the key to prevent secondary spinal cord injury. After an accident. It takes some time for the first responders to arrive at the scene, and only 28.1% of the first responders carry out the first handling at the scene, and the rest are non-professionals carrying out the first handling, so it is crucial to promote the correct handling method among the masses to improve self-help ability. When performing first aid at the scene, the first thing to do is to determine the vital signs of the injured person, keep his or her airway open, and maintain heartbeat and blood pressure. Secondly, the injured person’s spine and spinal cord should be judged according to the perception of the injured person’s limbs, and then different handling methods should be adopted according to the injury site. For quadriplegia suspected to be cervical spinal cord injury, one person should protect the head and neck of the casualty with both hands, and three people should use both hands to support the back of the neck, torso and buttocks, upper and lower limbs from below the casualty’s body and move to a hardboard stretcher. Use clothing or towel rolls on both sides of the head and neck on the stretcher for temporary fixation, and if available, it is best to wear a collar brake to prevent the head and neck from swaying left and right during transport, which may aggravate spinal cord injury or be life-threatening. Double lower limb paralysis suspected of thoracolumbar spinal cord injury, transport should be lying down, straighten the limbs, do not twist the spine, by three people with both hands to place the casualty on a rigid stretcher flat. If there is no hard stretcher, and can not use soft blankets, sheets and other materials, should be taken locally, such as door panels or flat. In short, during the lifting and the whole transportation process, always pay attention to prevent the casualty’s spine from twisting and bending to avoid secondary injury. Secondary spinal cord injury does not only occur at the scene of emergency care, but may also occur during hospitalization, rehabilitation and care due to improper measures or lack of knowledge on the part of the patient and family. To help patients enhance their awareness of spinal cord secondary injury prevention, such as doctors and rehabilitators when implementing treatment and rehabilitation for patients, and nurses when implementing turning, moving or health education for patients, they must teach patients the correct methods to ensure that they can obtain and master the correct standardized knowledge and skills of rehabilitation care to effectively prevent secondary spinal cord injury.
