Wash the wound surface with isotonic saline to remove foreign bodies and dirt from the wound surface. Protect small blisters from breakage, and large blisters can be pumped out with an empty needle. For broken blisters or heavily contaminated ones, the skin of the blister should be cut off, and the trauma surface should be gently rolled over with gauze, covered with a layer of liquid paraffin gauze or thin layer of petroleum jelly gauze, plus multiple layers of skimmed gauze and cotton pads, and evenly wrapped with bandages and pressure, and burns can also be treated with bandage therapy and exposure therapy.
