First aid for burns Once a burn has occurred, immediately place the scalded area under running water or apply a cold compress with a cool towel, or if the burn is large, the injured person should immerse the entire body in a bathtub filled with cold water. Gauze or bandages can be loosely wrapped around the burn to protect the wound. Try to preserve the integrity of the blister skin after the burn. Clothing, if any, should be cut off to avoid damaging the integrity of the blister skin during the process of undressing. Prohibited Ice should not be used to treat burns, as ice can damage the already broken skin causing the wound to deteriorate. Do not break the blisters as this will leave scars. Do not apply antibiotic ointment or grease casually to the wound either, as these sticky substances can easily lead to secondary infection. Caution Third-degree burns, electrical burns, and burns from chemicals must be seen by a doctor. In addition, if the patient has a cough, watery eyes or difficulty breathing, professional medical help is required. Patients with second-degree burns that are larger than the palm of the hand should also be seen in a hospital, where professional treatment can prevent scarring.
