1. Generally, the skin of burn patients is burning, red and swollen, with few or small blisters. At this time, it is necessary to wash the injured part with cold water or soak the skin with water to reduce the surface temperature, and then apply egg white and general scald ointment. Generally, it can be recovered in about two days, leaving no scars.

2. Patients with mild burns and scalds will have large blisters on the skin surface, local redness and swelling, accompanied by severe pain. At this time, if the blister is not broken, it can be washed with cold water to cool down, then the blister is broken with a sterilized needle, and the water flowing out is wiped off, and then the scald ointment is applied and bandaged with gauze, and the dressing is changed once a day or two, and it can be recovered in a week or so, leaving no scars.

3. Patients with severe burns and scalds, such as fire swelling, are likely to burn their skin to black at this time. In severe cases, a large amount of skin tissue is damaged. In this case, the wound should be treated simply to prevent the infection of the injured part from getting worse, then simply bandaged and sent to the hospital immediately. For severe patients, when the burn area is too large, cosmetic surgery and skin transplantation are needed in the later stage, which will bring great harm to the patient's body, spirit and economy.
