· First-degree burns affect only the outer layer of the skin. They cause pain, redness, and swelling.
· Second-degree burns affect both the outer and underlying layer of skin. They cause pain, redness, swelling, and blistering. They are also called partial thickness burns.
· Third-degree burns affect the deep layers of skin. They are also called full thickness burns. They cause white or blackened, burned skin. The skin may be numb.
Burns fall into 2 groups.
Minor burns are:
· First degree burns anywhere on the body
· Second degree burns less than 2 to 3 inches (5 to 7.5 centimeters) wide
Major burns include:
· Third-degree burns
· Second-degree burns more than 2 to 3 inches (5 to 7.5 centimeters) wide
· Second-degree burns on the hands, feet, face, groin, buttocks, or over a major joint
You can have more than 1 type of burn at a time.
Severe burns need urgent medical care. This can help prevent scarring, disability, and deformity.
Burns on the face, hands, feet, and genitals can be particularly serious.
Children under age 4 and adults over age 60 have a higher chance of complications and death from severe burns because their skin tends to be thinner than in other age groups.
Before giving first aid, it is important to determine what type of burn the person has. If you are not sure, treat it as a major burn. Serious burns need medical care right away. Call your local emergency number or 911.
MINOR BURNS
If the skin is unbroken:
· Run cool water over the area of the burn or soak it in a cool water bath (not ice water). Keep the area under water for at least 5 minutes. A clean, cold, wet towel will help reduce pain.
· Calm and reassure the person.
· After flushing or soaking the burn, cover it with a dry, sterile bandage or clean dressing.
· Protect the burn from pressure and friction.
· Over-the-counter ibuprofen or acetaminophen can help relieve pain and swelling. Do NOT give aspirin to children under 12.
· Once the skin has cooled, moisturizing lotion also can help.
Minor burns will often heal without further treatment. Make sure the person is up to date on their tetanus immunization.
MAJOR BURNS
If someone is on fire, tell the person to stop, drop, and roll. Then, follow these steps:
· Wrap the person in thick material; such as a wool or cotton coat, rug, or blanket. This helps put out the flames.
· Pour water on the person.
· Call 911 or your local emergency number.
· Make sure that the person is no longer touching any burning or smoking materials.
· Do NOT remove burned clothing that is stuck to the skin.
· Make sure the person is breathing. If necessary, begin rescue breathing and CPR.
· Cover the burn area with a dry sterile bandage (if available) or clean cloth. A sheet will do if the burned area is large. Do NOT apply any ointments. Avoid breaking burn blisters.
· If fingers or toes have been burned, separate them with dry, sterile, non-sticky bandage.
· Raise the body part that is burned above the level of the heart.
· Protect the burn area from pressure and friction.
· If an electrical injury may have caused the burn, DO NOT touch the victim directly. Use a non-metallic object to move the person away from exposed wires before starting first aid.
You will also need to prevent shock. If the person does not have a head, neck, back, or leg injury, follow these steps:
· Lay the person flat
· Raise the feet about 12 inches (30 centimeters)
· Cover the person with a coat or blanket
Continue to monitor the person's pulse, rate of breathing, and blood pressure until medical help arrives.
Also call a provider right away if symptoms of dehydration occur with a burn:
· Decreased urination
· Dizziness
· Dry skin
· Headache
· Lightheadedness
· Nausea (with or without vomiting)
· Thirst
Children, older people, and anyone with a weakened immune system (for example, from HIV) should be seen right away.
The provider will perform a history and physical examination. Tests and procedures will be done as needed.
These may include:
· Airway and breathing support, including a face mask, tube through the mouth into the trachea, or breathing machine (ventilator) for serious burns or those involving the face or airway
· Blood and urine tests if shock or other complications are present
· EKG (electrocardiogram, or heart tracing), if shock or other complications are present
· Intravenous fluids (fluids through a vein), if shock or other complications are present
· Medicines for pain relief and to prevent infection
· Ointments or creams applied to the burned areas
· Tetanus immunization, if not up to date
The outcome will depend on the type (degree), extent, and location of the burn. It also depends upon whether internal organs have been affected, and if other trauma has occurred. Burns can leave permanent scars. They can also be more sensitive to temperature and light than normal skin. Sensitive areas, such as the eyes, nose, or ears, may be badly injured and have lost normal function.
With airway burns, the person may have less breathing capacity and permanent lung damage. Severe burns that affect the joints may result in contractures, leaving the joint with decreased movement and a reduction in function.
Ожоги третьей степени (их еще называют полнослойные ожоги) поражают все слои кожи и подкожно-жировую клетчатку. Это очень серьезные ожоги, которые могут нарушить способность кожи к регенерации.
Ожог третьей степени может вызывать сильную боль. Однако в случае повреждения неврных окончаний боли в первый момент после ожога может не быть. Ожоги третьей степени внешне могут иметь белый цвет, вишневый или черный, и цвет их не меняется при надавливании (не белеют). Хотя могут образоваться пузыри, обычно такие ожоги сухие, твердые, похожи на выделанную кожу.
Чаще всего ожоги третьей степени вызываются паром, горячим маслом, салом, химическими веществами, электрическим током и горячими жидкостями.
При ожогах третьей степени самая большая проблема – это инфекция. При этих ожогах всегда требуется помощь врача. При небольших по площади ожогах может нарасти новая кожа с соседних необожженных участков. При обширных ожогах может потребоваться хирургическая кожная пластика.
