After the occurrence of burns, on-site first aid is very important, and the key is to grab time, which is related to whether the healing of burns is good.

(2) take “cold therapy” measures, first of all, do not panic, and do not rush to take off the body thin such as sweatshirt, stockings and other clothing, should be quickly with cold water continuous rinse the injured part, or place the injury in a container of cold water soak, for 30 minutes, to get away from the cold source of pain has been significantly reduced shall prevail. Wait for cooling before you can carefully take off your clothes, so as not to tear the blisters formed after the scalding This can make the injury quickly and thoroughly heat, so that the skin vasoconstriction, reduce exudation and edema, relieve pain, reduce blister formation and prevent scar formation on the trauma. The purpose of cold water rinsing is to relieve pain, reduce exudation and swelling, and thus avoid or reduce blister formation. If the burn is on the finger, a cold water bath can also be used. Cold compresses can be applied to areas such as the face that cannot be rinsed or bathed. After the cold water treatment, wipe the wound surface dry, then thinly apply some blue oil hydrocarbon, green ointment and other ointment-type drugs, and then properly bandage for 1~2 days to prevent blistering. However, the face can only be exposed, no need to wrap. If a blister is formed, use a sterilized syringe to draw or cut a small hole to release the water; if the blister is broken, use a sterilized cotton ball to swab dry to keep it dry and not to make the water accumulate into a block. If you burn 1~2 fingers, you can also use a simple method – immersion in soy sauce, i.e., use a small cup of soy sauce to invade your fingers for about half an hour to stop the pain, and not blistering.

Do not use ice water to avoid frostbite. (4) Blisters can be punctured with a sterile needle in a low position, and the trauma should be protected by a sterile dressing or clean clothing cover when moving the body. (5) Do not use colored liquid such as red and purple potion on the trauma surface to avoid affecting the doctor’s judgment of the depth of the burn, and do not use alkaline surface, soy sauce, toothpaste, etc. indiscriminately to avoid infection or deepening of the trauma surface.
