1. Stop bleeding
When trauma occurs, hemostasis is one of the most urgent tasks. If you lose a lot of blood, it may lead to shock and life-threatening. The most common hemostasis technique is to directly compress the wound. In order to enhance the hemostatic effect, a tourniquet or hemostatic agent can be used. However, it should be noted that the use of tourniquets requires professional training.
bind up
Bandage is another important technique in trauma rescue. It can help control bleeding and protect wounds. Before dressing, the wound needs cleaning and disinfection. It is best to use sterile gauze or medical gauze for dressing. If the wound is deep, it is recommended to seek medical assistance.
repair
Fixation refers to the use of bandages or other materials around the wound to reduce pain and further injury. The most common fixation method is to use bandages. If it is a fracture or dislocation, it needs to be fixed as soon as possible to avoid aggravating the injury.
carry
Treatment refers to the transfer of the wounded from the scene of the accident to a medical rescue point or hospital. Before treatment, preliminary rescue and treatment are needed. In the process of handling, attention should be paid to the posture and movement stability of the injured. If the injury is serious, it is recommended to use a stretcher or other professional handling equipment.
To sum up, the four techniques of trauma rescue include hemostasis, dressing, fixation and treatment. In an emergency, these technologies can help save lives. However, it should be noted that if the injury is serious, it is recommended to seek professional medical assistance.
