Quick Answer
Seek medical attention for a burn injury if the burn covers more than 10% of the body surface area, affects the hands, feet, face, or genital areas, or is deep or blistered. Additionally, monitor for signs of infection, such as increased redness, swelling, or pus.
Recognizing the Severity of Burns
Burn injuries can be categorized into different levels of severity, with first-degree burns being the mildest and fourth-degree burns being the most severe. In general, first aid for minor burns can be provided at home, but more severe burns require medical attention. A burn that covers more than 10% of the body surface area is considered severe and requires medical care. To estimate the body surface area affected by a burn, use the “rule of nines”: the head and neck count for 9%, each arm counts for 9%, each leg counts for 18%, and the front and back of the torso each count for 18%. If a burn covers more than one of these areas, add the percentages together.
Monitoring for Signs of Infection
Even minor burns can become infected if not properly cared for. Monitor the burn for signs of infection, such as increased redness or swelling around the burn area, pus or discharge, or a foul odor. If you notice any of these symptoms, seek medical attention immediately. Additionally, monitor for fever, chills, or a general feeling of being unwell. If you experience any of these symptoms, seek medical attention, as they may indicate a more serious infection.
When to Seek Medical Attention
In addition to burns that cover more than 10% of the body surface area, seek medical attention if the burn affects the hands, feet, face, or genital areas. These areas have a higher risk of complications and require prompt medical attention. Burn wounds in these areas can lead to contractures, scarring, and permanent damage if not properly treated. If you are unsure about the severity of a burn or the best course of treatment, seek medical attention for guidance and care.
