Burns and Electric Shock
Most burns are minor injuries that occur at home or work. It is common to get a minor burn from hot water, a curling iron, or touching a hot stove. Home treatment is usually all that is needed for healing and to prevent other problems, such as infection.
There are many types of burns.
- Heat burns (thermal burns) are caused by fire, steam, hot objects, or hot liquids. Scald burns from hot liquids are the most common burns to children and older adults.
- Cold temperature burns are caused by skin exposure to Reference wet, windy, or cold conditions.
- Electrical burns are caused by contact with electrical sources or by lightning.
- Chemical burns are caused by contact with household or industrial chemicals in a liquid, solid, or gas form. Natural foods such as Reference chili peppers, which contain a substance irritating to the skin, can cause a burning sensation.
- Radiation burns are caused by the sun, tanning booths, sunlamps, X-rays, or radiation therapy for cancer treatment.
- Friction burns are caused by contact with any hard surface such as roads ("road rash"), carpets, or gym floor surfaces. They are usually both a scrape (abrasion) and a heat burn. Athletes who fall on floors, courts, or tracks may get Reference friction burns Opens New Window to the skin. Motorcycle or bicycle riders who have road accidents while not wearing protective clothing also may get friction burns. For information on treatment for friction burns, see the topic Reference Scrapes.
Breathing in hot air or gases can injure your lungs (Reference inhalation injuries Opens New Window). Breathing in toxic gases, such as Reference carbon monoxide Opens New Window, can cause poisoning.
Burns injure the skin layers and can also injure other parts of the body, such as muscles, blood vessels, nerves, lungs, and eyes. Burns are defined as first-, second-, third-, or fourth-degree, depending on how many Reference layers of skin and tissue Opens New Window Reference Opens New Window are burned. The deeper the burn and the larger the burned area, the more serious the burn is.
- Reference First-degree burns Opens New Window are burns of the first layer of skin. See a picture of a Reference first-degree burn Opens New Window Reference Opens New Window.
- There are two types of
Reference second-degree burns Opens New Window:
- Superficial partial-thickness burns injure the first and second layers of skin. See a picture of this type of Reference second-degree burn Opens New Window Reference Opens New Window.
- Deep partial-thickness burns injure deeper skin layers. See a picture of this type of Reference deep second-degree burn Opens New Window Reference Opens New Window.
- Reference Third-degree burns Opens New Window (full-thickness burns) injure all the skin layers and tissue under the skin. See a picture of a Reference third-degree burn Opens New Window Reference Opens New Window. These burns always require medical treatment.
- Fourth-degree burns extend through the skin to injure muscle, Reference ligaments Opens New Window, Reference tendons Opens New Window, nerves, blood vessels, and bones. These burns always require medical treatment.
The Reference seriousness of a burn is determined by several things, including:
- The depth, size, cause, affected body area, age, and health of the burn victim.
- Any other injuries that occurred, and the need for follow-up care.
Burns affect people of all ages, though some are at higher risk than others.
- Most burns that occur in children younger than age 5 are scald burns from hot liquids.
- Over half of all burns occur in the 18- to 64-year-old age group.
- Older adults are at a higher risk for burns, mostly scald burns from hot liquids.
- Men are twice as likely to have burn injuries as women.
Burns in children
Babies and young children may have a more severe reaction from a burn than an adult. A burn in an adult may cause a minor loss of fluids from the body, but in a baby or young child, the same size and depth of a burn may cause a severe fluid loss.
A child's age determines how safe his or her environment needs to be, as well as how much the child needs to be supervised. At each stage of a child's life, look for burn hazards and use appropriate Reference safety measures. Since most burns happen in the home, simple safety measures decrease the chance of anyone getting burned. See the Reference Prevention section of this topic.
When a child or Reference vulnerable adult Opens New Window is burned, it is important to find out how the burn happened. If the reported cause of the burn does not match how the burn looks, Reference abuse must be considered. Self-inflicted burns will require treatment as well as an evaluation of the person's emotional health.
Infection is a concern with all burns. Watch for Reference signs of infection Opens New Window during the healing process. Home treatment for a minor burn will reduce the risk of infection. Deep burns with open blisters are more likely to become infected and need medical treatment.
