First-Degree Burns: |
| |
First-degree burns are caused by a flash, a flame, or the sun. They are the most common and the most minor of all burns. The skin surface is dry; no blisters or swelling occur. The skin is reddened and extremely painful, but the epidermal layer is the only one affected. First-degree burns heal in two to five days with no scarring. Peeling of the outer epidermal layer usually occurs, and some temporary discoloration may result |

Second-Degree Burns: |
| |
Second-degree burns result from contact with hot liquids or solids, flash or fame contact with clothing, direct fame from fires, and contact with chemical substances. The skin appears moist and mottled, and it ranges in color from white to cherry red. The burned area is extremely painful. The epidermis and dermal layers of skin are usually burned, and damage may result to some fat domes of the subcutaneous (fatty tissue lust under the skin) layer. Second-degree burns are considered minor if they involve less than 15 percent of the body surface in adults and less than 10 percent in children. Fifteen to 30 percent of adult body surface and 10 to 20 percent of a child's body surface indicates a moderate second degree burn. The burn is also considered moderate if it involves the face, hands, feet, or genital area. A second-degree burn is considered critical if it involves more than 30 percent of the total body surface in an adult and 20 percent in a child. Healing of a minor second-degree burn usually requires five to twenty-one days. If infection occurs, healing time is extended to over thirty-five days, and the burn is con- sidered third-degree. |
