1, in principle, first aid for trauma is to rescue first, then fix it, and then send it to the hospital, and pay attention to taking measures to prevent the injury from aggravating or polluting. Need to be sent to hospital for treatment, should immediately take measures to protect the wounded before being sent to hospital for treatment.

2. Before the rescue, let the wounded lie down quietly and judge the general situation and degree of injury, such as bleeding, fracture and shock.

3, external bleeding immediately take hemostatic measures to prevent excessive blood loss and shock. If he is not injured in appearance, but he is in a state of shock, unconsciousness or coma, we should consider the possibility of injury to the internal organs or brain in the chest and abdomen.

4, in order to prevent wound infection, application of clean cloth cover. Paramedics are not allowed to touch the wound directly with their hands, and are not allowed to stuff anything into the wound or use drugs casually.

5, when handling should make the wounded lie flat on a stretcher, waist beam on a stretcher, in case of falling. When carrying on the flat ground, the head of the wounded is behind, and when going upstairs, downstairs and downhill, the head is above. During handling, the wounded should be closely observed to prevent sudden changes in the injury.

6. Wound oozing: Cover the wound with several layers of sterile gauze slightly larger than the wound, and then wrap it. If there is still more oozing blood after dressing, bandage can be added to stop bleeding properly.

7. When the wound bleeding is jet or bright red blood gushes out, immediately press the bleeding point (near the heart) with clean fingers to block the blood flow, and raise or raise the bleeding limb to reduce the amount of bleeding.

8. When using a tourniquet or a cloth belt with good elasticity to stop bleeding, you should first use several layers of soft cloth or the sleeves of the wounded under the tourniquet, and then tighten the tourniquet, just to make the pulse of the limb artery disappear. The upper limbs are relaxed every 60 minutes, and the lower limbs are relaxed every 80 minutes. After each relaxation 1-2 minutes, the time to start tightening and relaxing is marked by words next to the tourniquet. The tightening time should not exceed four hours. Do not use tourniquet in the third part of the upper arm and armpit to avoid nerve damage.
