    In the emergency process of using the spine board stretcher to carry patients, emergency nurses should also work together, and the method must be appropriate, otherwise it will lead to serious consequences.

     

     

    3. Precautions for using stretcher

    (1) Check the wounded

    Before transporting the wounded, check the wounded's vital signs and injured parts, focusing on checking whether the wounded's head, spine, and chest have trauma, especially whether the cervical spine is injured.

    (2) The wounded must be properly handled

    First, keep the airway of the injured person unobstructed, and then stop the bleeding, bandage, and fix the injured part of the wounded according to the technical operation specifications. It can only be moved after proper handling.

    (3) Do not carry the personnel or stretchers when they are not ready.

    Be comprehensive when handling overweight and delirious casualties. You can choose to use electric loading stretchers, basket stretchers, etc. for transportation. At the same time, it is necessary to prevent accidents such as falls and injuries during transportation.

    (4) During the transportation process, the changes in the condition of the wounded should be observed at any time.

    Focus on observing breathing, consciousness, etc., of the wounded, pay attention to keep him warm, but do not cover the head and face too tightly, so as not to affect breathing. In the event of an emergency situation on the way, such as suffocation, respiratory arrest, convulsions, stop handling and conduct first aid immediately.

    (5 )In a special site, it should be handled according to a special method.

    At the scene of the fire, when transporting the wounded in the thick smoke, the rescue staff should bend over or crawl forward; at the scene of the leakage of toxic gas, the transporter should first cover the mouth and nose with a wet towel or use a gas mask to avoid being fumigated by the gas.

    During the transportation of the wounded, the wounded must be turned every half an hour. For the paraplegic and the wounded with extensive burns, a soft stretcher can be used to cover it and fasten it with a strap, and then the wounded will be turned over in one direction.

    After the casualty is turned over, massage the skin of the protruding part. When marching, the head of the wounded should be placed behind and the feet at the front, so as to observe the facial expressions and breathing of the wounded.

     Carrying the injured of the spine and spinal cord injury:

    After being placed on the spine board stretcher, the body and the stretcher must be firmly fixed with a triangle towel or other cloth strips, especially for those with cervical spine injuries, sandbags, pillows, clothing, etc. must be placed on both sides of the head and neck for fixation to limit the cervical spine. Then use a triangle towel to fix the forehead together with the stretcher, and then use a triangle towel to surround the whole body with the stretcher.

    (7) Pay attention to the effect of weather on the wounded

    When transporting the wounded on a stretcher in cold conditions, attention should be paid to keeping him warm. Hot water bottles and military water bottles can be placed in the quilt. When transporting the wounded on a stretcher in the rainy season at night, cover the wounded with a rain cloth to prevent the wounded from getting wet in the rain. When transporting the wounded under hot conditions, the wounded should be protected from the sun to prevent heat stroke. During the transportation, the changes of the wounded's condition should be continuously observed, and pressure bandaging should be applied to stop the bleeding the wounds.
