Second Degree Burns
When the epidermis and part of the dermis of the skin are involved in any burn injury, it is known as a second-degree burn. Depending on the level of nerve involvement, the severity of the pain varies in second-degree burns. In the case of second-degree burns, in addition to superficial blistering, there is accumulation of clear liquid in the area. Involving superficial or papillary dermis, second-degree burns sometimes involve the reticular or deep layer of the dermis.
When the skin experiences any burn or surface damage, the surrounding layer of the skin expands resulting in a blister. The Plasma or serum is released as the result of the damaged Keratinocytes - outermost layer of the skin. The released plasma /serum helps to prevent further damage and also to help in the healing process. This is the reason why blisters should not be punctured as it would invite infection to the affected skin. The serous fluid will be reabsorbed by the skin usually after 24 hours if there is no infection.
According to the severity of these burns, they are further classified as deep or superficial. When only the outermost part of the dermis is involved, it is called superficial. Extreme pain and hypersensitivity to touch are characteristics of superficial burns. Appearing moist and red or mottled pink in color, the skin at the area of the burn blanches on pressure. Usually blisters appear after some time. Normally, this kind of superficial second - degree or partial thickness burns heal by themselves.
Blood Blister : This ensues when a part of the skin is pinched or crushed with force. The capillaries affected by the force rupture leaking blood into the skin.
Tissue destruction to the deeper layers of the dermis is involved in deep second - degree and deep partial thickness burns. In contrast to the superficial type, these deep second -degree burns are usually dry and whitish in appearance, but they may appear like superficial burns. Normally pain is associated with this type of burns, though the skin does not blanch. It may take three to four weeks for the burn to heal. Thick or hypertrophic scars may remain even after the injury heals.
Causes of a second-degree burn include scald injuries, flames and a brief contact of the skin with a hot object. Sometimes deep sunburn, contact with hot liquids or chemicals and burning gasoline or kerosene also may cause second-degree burns. With second degree burns, the skin color turns to deep red and you will notice blisters. The burnt area appears shiny and moist. Second-degree burns that are only superficial normally heal in about three weeks. Care should be taken to keep the wound clean and protected. For effective treatment of second degree burns, the following conditions are considered:
Person affected by burns of this type may go into shock, since they lose lots of fluid from the burned site, if the injury involves more than 10% of skin. If a second-degree burn is greater than 2 or 3 inches in diameter, only a medical professional should treat it. It is safe to treat a burn like this at home only when it is a smaller. According to the severity of the burn, treatment may vary from antibiotic ointments to systemic antibiotics. Every day cleaning of the wound is necessary to remove dead skin. Depending on the severity of the burn, the dressing should be changed at least once or twice a day. It may be painful for the patient when the dressing is changed. A pain reliever or analgesic will help to reduce the pain. Care should be taken not to burst any blisters that have formed.
First Aid for second-degree burns
When there are open blisters following second-degree burns:
Third degree burns
Every layer of the skin is involved in third-degree burns. Even after the treatment, only the edges heal because they are so deep. If skin grafting is not carried out, in the long run the burned area will be covered with scars. Affecting the epidermis, dermis and hypodermis, third-degree burns cause charring of the skin. The skin appears white and translucent and you can see coagulated vessels just beneath the skin surface. Even though the burned areas may be numb, there may be some pain. This may be due to associated with it. Since the skin tissue and the structures are destroyed, healing from third-degree burns is very slow. New skin will not grow in this area since the epidermis and hair follicles are destroyed.
Third degree burns occur when clothing coming into contact with fire or corrosive chemicals. Accidental contact with hot objects, flames or electricity can cause third degree burns. The skin turns white or it may turn black or brown and leathery. Though little pain may be experienced in the burned area because nerve endings have been destroyed, pain will be more in the surrounding areas. Some of the other symptoms that are noticed include redness, peeling skin, shock and pale clammy skin associated with weakness, bluish lips and nails.
Medical treatment is necessary for all third-degree burns. If you notice a person's clothes burning ask him or her not to run in panic. It will aggravate the flames and they may rise even up to the person's face. With the help of a blanket, jacket or rug you can suppress the flames all along rolling the person on the ground. If the clothing has stuck to the burn do not try to remove it. Applying ice water, lotions, sprays, ointments or home remedies is not advisable.
Since swelling is a possibility, remove jewelry and tight clothing from the burned. In order to bring the body temperature back to normal, apply cold moist cloths for brief periods or immerse the burned area in cold water. Care should be taken for not to leave the burned area in cold water too long for it will result in cooling down the body very much. There may be signs of shock such as rapid or faint pulse, nausea and vomiting and rapid and shallow breathing. Call for medical help if the person undergoes shock. Unless it is warranted do not move the person. In case vomiting occurs, the person should be asked to lye on their side to prevent choking. Keep the feet raised unless the person has breathing problems. In order to conserve body heat, cover the person with a blanket. You can give small sips of water or clear juice, if the person remains conscious and if the medical help may require some time to reach, provided there is no vomiting. Moistening the lips will do if the person is in shock since drinking more water will induce vomiting. Never give alcohol to a person who is in shock.
Chemical burns: Clothing and jewelry on which the chemical has spilled should be removed. With running water, wash out liquid chemicals for 15 to 20 minutes avoiding splashing the chemical in the eyes. If large amounts of water are not available immediately, clear dry chemicals away from the skin since some chemicals get activated by small quantity of water. A dry and loose bandage can be given to cover the burn.
Electric burns: A health care provider should be called for to examine any electrical burn. Though an electrical burn may seem to cause little damage, because it extends deeply into the tissues underneath the skin the damage may be more. For many hours the damage may not surface. The burned area may be covered with a dry, non-fluffy loose bandage. Applying any ointment or other substances should be strictly avoided.
Hospitalization may be required for a few days or for several weeks for third-degree burns and scars. Depending on the severity of the burns, several operations by a medical plastic surgeon may be required to get rid of the scars. Treatment at a burn center is usually necessary for wide spread burns.
First Degree Burns
Burns are classified as first-degree burns, second-degree burns and third-degree burns according to their severity. In the case of first-degree burns, only the outer layer of the skin is affected. Swelling, pain and redness is the resulting discomfort caused by this type of burns. Dry heat like fire, wet heat such as steam or boiling liquids, heated objects, sun, chemicals, electricity and friction accidentally become the causes for burns. When hot metals, scalding liquids, flames or steam accidentally gets into contact with one's skin, thermal burns occur. They can also occur due to fire and automobile accidents, electrical malfunctions and space heaters. Unsafe handling of firecrackers and kitchen accidents are some of the other causes for thermal burns. Inhaling smoke, steam, toxic fumes and superheated air in a badly ventilated space can cause burns to the airways.
The severity of the burn is not directly proportional to the degree of pain. The most serious burns often occur with less pain. Blisters occur at the place of the burn. There will be peeling of the skin and it will turn red. Pale and clammy skin, weakness and drop in alertness are often noticed with the shock due to burns. Lips and fingernails may turn blue due to shock. Swelling and white or charred skin also are some of the symptoms. If burns affect the airways, the symptoms may vary from charred mouth, burned lips, wheezing and difficulty in breathing. There may be a change in voice of the patient. A dark, carbon-stained mucus will ooze out from the place of the burn. Sunburn can be classified as a first-degree burn.
