A burn is an injury to the tissues of the body. Burns are classified according to the amount of tissue they affect and how deep they are. A third-degree burn is the most serious because it destroys all the layers of the skin.
Who gets it?
Anyone can get a third-degree burn. Children and the elderly are more likely to experience complications from burns.
What causes it?
People are more likely to suffer third-degree burns from contact with corrosive chemicals, flames, electricity, or extremely hot objects; immersion of the body in extremely hot water, or clothing that catches fire.
What are the symptoms?
Skin with a third-degree burn may appear white or black and leathery on the surface. Because the nerve endings in the skin are destroyed, the burned area may not be painful, but the area around the burn may be extremely painful. Pain causes the breathing rate and pulse to increase. Some areas of the burn may appear bright red, or may blister. Third-degree burns can also damage fat, muscle, and bone. Electrical burns damage the deep tissues. Often only the area of the skin where the electricity entered the body looks black and charred. Electrical shocks can make a person stop breathing and interrupt the rhythm of the heart. Third-degree burns can cause the victim to go into shock. Shock occurs when loss of fluids causes the blood pressure to become so low that not enough blood reaches the brain and other major organs. The symptoms of shock include fainting, general weakness, nausea and vomiting, rapid pulse and breathing, a blue tinge to the lips and finger nails, and pale, cold, moist skin. If the victim has been burned in a fire and has been exposed to large amounts of smoke, he or she may also have chest pain, red and burning eyes, and a cough. All third-degree burns require emergency medical treatment.
How is it diagnosed?
Your doctor will examine the burned area and classify it according to the amount of tissue affected and the depth of the burn. He or she will ask how the burn occurred. The doctor will check for other conditions related to burn injuries, such as smoke inhalation, carbon monoxide poisoning, or other injuries. If the patient is a child, the doctor will ask further questions to ensure the patient is not a victim of child abuse. Doctors assess the severity of a burn by determining what percentage of the total body surface area (BSA) is affected. In patients older than nine years, they apply what’s called the “rule of nines” to determine the percentage of BSA. For example, the genital area is considered 1% of BSA. The head and neck are 9%. Burns on each arm, including the hand, is also 9% of BSA. Each leg, including the foot, is 18%. The front of the torso is 18%, as is the back of the torso, including the buttocks. In children younger than nine, the palm of the child’s hand is used as a measure of 1% of BSA. Third-degree burns that cover less than 2% of BSA are considered minor. Third-degree burns that cover 2 to 10% of BSA are considered moderate burns. Those that cover more than 10% of BSA, as well as those on the face, hands, feet, or genitals, are critical.
What is the treatment?
All third-degree burns require medical treatment. Minor third-degree burns can be treated in a doctor’s office, but all others should be considered a medical emergency that requires hospital treatment, usually in a burn unit. Call 911, or get the person to an emergency room as soon as possible. If the person is on fire, do not let him or her run. Smother any flames with a blanket, jacket, or water, if available, or have the victim use the “stop, drop, and roll” method. Remove any clothing or jewelry from the injured area, but DO NOT remove clothing if it is stuck to the burn. Very briefly immerse the burned area in cold water or use a clean towel or wash cloth moistened with cold water to stop the burning process. Don’t hold the burned area in cold water for too long or you will cool down the body too much. Also don’t use ice or ice water because they will further damage the tissue. Do not break open any blisters, or there will be a greater risk of infection. If the blisters are open, don’t remove any clothing that might be stuck to the burn, and don’t run water over the burn. This will increase the risk of shock. Whether the blisters are broken or not, you can place a dry, sterile gauze pad over the burn, but do not use any bandages with adhesive. If the burned area is larger, lightly drape a clean sheet over it to protect it until you get medical treatment. It is important for the bandage to be loose so the burn gets air.
Never apply butter, oils, or burn ointments. They make it more difficult for the burn to heal and can actually make the burn worse because the heat can’t escape. Arms or legs that are burned should be kept raised to reduce the amount of swelling. If the face or neck are burned, raise the person’s head slightly. This will also help if he or she is having trouble breathing. If the person appears to be going into shock, lay him or her flat on the ground, raise the feet around 12 inches (30 cm), and call for medical help. You can cover the patient with a blanket to keep him or her warm.
Do not give a person who is in shock anything to drink. Otherwise, you can provide the patient with small sips of clear liquid, such as water or juice.
Chemical burns are treated a little differently. For liquid chemicals, first remove any clothing or other items that the chemicals have spilled on. Then, thoroughly wash any chemicals off the skin under running water for 15 to 30 minutes. For dry chemicals, use large amounts of water to flush the chemicals from the skin. Never use small amounts of water because they may actually activate the chemicals. If no water is available, use a clean cloth to brush any dry chemicals off the skin. Loosely cover the burn with a dry, sterile bandage, and see a doctor for further treatment. Different chemicals have different effects, so you should always check the chemical label, if possible, for additional directions. Always see a doctor if the chemicals have gotten into the eyes or mouth. If a person has had contact with electricity, call 911 and make sure the source of the electrical current is disconnected before touching the victim. Administer emergency cardiopulmonary resuscitation (CPR) if the victim’s heart has stopped beating or he or she is having trouble breathing. Lightly cover the burned area with a dry, sterile bandage until medical help arrives.
Moderate and critical third-degree burns require hospitalization. The body loses a great deal of fluid through the burned area, so replacement fluids are given through an intravenous (IV) line, which is a tube placed into a vein. If the lungs are damaged, or breathing is difficult, a tube is inserted into the throat to help with breathing. The patient will need to take antibiotics to protect the burned area from infection, as well as a prescription pain medication. If the patient’s immunizations aren’t up to date, he or she may also need a tetanus booster. Sometime severe burns are treated by putting the patient into a special room that is filled with pure oxygen under high pressure. This is called a hyperbaric chamber, and the patient must receive this treatment within 24 hours of being burned for the treatment to be effective. The burned areas are cleaned and covered with an antibiotic cream, then covered in sterile bandages. These bandages are changed frequently and the burned area is carefully monitored for signs of infection. The dead tissue around the burn is surgically removed, called debridement.
As burned skin heals, it develops a thick, scabbed surface, called eschar, that makes it difficult for blood to flow to the injured area. Doctors often have to use a procedure called an escharotomy to cut through the eschar so the healthy tissue underneath can receive the blood flow it needs. Severe third-degree burns leave extensive scars because the burns are so deep. For this reason, the burned area may need to be covered with a skin graft, where a piece of healthy skin is taken from an unburned area of the body and transplanted permanently to the burned area. This is called an autograft. If the patient’s skin can’t be used, the plastic surgeon may use the skin of another human donor (called an allograft), or the skin of an animal, such as a pig (called a xenograft). Allografts and xenografts are temporary, but protect the skin as it heals. Critical third-degree burns may take weeks to months of hospital treatment and require physical therapy to help restore movement to the burned areas and to minimize scarring.
Self-care tips
Many burns occur at home and could have been prevented. You can avoid first-degree burns by handling hot liquids and objects carefully. Make sure electrical cords are in good condition, household chemicals are safely stored and labeled, and hot beverages and objects are out of reach of small children. When handling chemicals, wear protective gloves and eyewear, and follow label directions for safe handling. Never wear clothing with long, loose sleeves while cooking or around any type of open fire. Never put a child into a tub unless you have first tested the water temperature. You can guard against burns from hot water by keeping your hot water heater set lower than 120 degrees Fahrenheit (49 degrees Celsius). Children should also sleep in flame-resistant pajamas or nightgowns. Do not smoke, or make sure discarded cigarettes are completely extinguished. Teach your children fire safety and make sure they do not have access to matches or lighters. You can also protect you and your family from burns by making sure you have operating smoke detectors on every floor of your house. Also check the temperature of a child’s car seat or seat belt before buckling the child in. Even these objects can cause burns after a period of time in direct sunlight. Never allow children to handle fireworks without adult supervision. Fireworks are a leading cause of burns and other injuries. You can avoid sunburns by using a sunscreen of at least a 15 SPF rating. Apply sunscreen liberally at least 20 minutes before sun exposure and reapply after swimming or sweating. Avoid spending time in the sun from 10 a.m. to 3 p.m., when the rays are strongest. Always take shelter during severe storms to avoid being struck by lightning.

If it really is a third degree burn, then you need to go to a doctor right away. A third degree burn is one that has caused damage pretty much all the way through your skin. There's often charred skin visible. A third degree burn may not hurt at all since the nerve endings are usually damaged. But medical attention is required since, depending on the surface area of the burn, third degree burns often require skin grafts. I doubt you actually have a third degree burn, but if you do, you should see a doctor immediately.
A second degree burn typically causes blisters, and if there's little or no nerve damage would usually be the most painful type of burn. If you have a burn that has formed blisters it would generally be a good idea to see a doctor if you're at all worried about it, or if it's really painful. A second degree burn should be rinsed with cold water immediately, and covered with a loose bandage.
A first degree burn would normally cause redness and minor pain at the site of the burn, but no blisters or charring. If the burn covers a large area or shows signs of infection, or if you have any other concerns about it, you should see a doctor, but most small first degree burns don't require medical attention. First degree burns should be rinsed with cold water and wrapped in a lose bandage.
For first and second degree burns that do NOT require medical attention, you can reduce the pain from the burn by taking an over the counter pain medication like Tylenol or Ibuprophen. Also, putting aloe gel on the burn can help cool it, and provide temporary relief. Antiseptic ontiments that contain pain relievers (such as Neosporin Plus) may also help. If it's still a problem, you should have the injury examined by a doctor, who, depending on the severity of the injury and the patient's history, may prescribe a stronger pain reliever.

Go to the doctor if it's that bad. Don't put ice, oil, or butter directly on it. Running cold water over it will help.
THIRD DEGREE Skin with a third-degree burn may appear white or black and leathery on the surface. Because the nerve endings in the skin are destroyed, the burned area may not be painful, but the area around the burn may be extremely painful. All third-degree burns require emergency medical treatment.
SECOND DEGREE Skin with a second-degree burn is extremely red and blistered, and may look wet because of fluid loss. Second degree burns are very painful, and the victim’s pulse rate usually increases in response to the pain. See a doctor immediately if a second-degree burn is on the face, hands, feet, or genitals; is caused by an electrical source; or covers an area larger than two to three inches.
FIRST DEGREE Skin with a first-degree burn is red, sore, and sensitive to the touch. It may also be moist, slightly swollen, or itchy. When lightly pressed, the reddened skin whitens, which is called blanching. See a doctor immediately if a burn is on the face, hands, feet, or genitals; is caused by an electrical source; or covers a very large area.
