Burns

Burns are injuries of the skin or other tissues, caused by contact with heat, radiation, chemicals or electricity. Burns according to their depth (2nd to 3rd degree *, editor’s note .: the degree of classification is adjusted..) And assigned to the percentage share of the total body surface area (% BSA). Complications and attendant problems include a hypovolemic shock, smoke injury, infection, scarring and stiffening. In patients with extensive burns (> 20% BSA) is a volume replacement therapy is needed. The treatment of burn wounds includes local antibacterial substances, regular cleaning, elevation and sometimes skin grafts. An intensive rehabilitation consisting of physical exercises that include the whole range of motion and splinting is often necessary.

In the USA veru rsachen burns about 3000 deaths a year and about 2 million emergency treatments. Thermal burns etiology can be of any external heat source resulting (flame, hot liquids, hot solid substances or, occasionally, vapors). Fire can also smoke poisoning have resulted (Kohlenmonxidvergiftung). Tips and risks The airways should be examined and prepared for intubation if patients have respiratory symptoms, carbonaceous sputum, perioral burns or singed nasal hairs or were trapped in a burning environment. Radiation burns often occur after prolonged exposure to ultraviolet rays of the sun (sunburn) before; However, they can (except sun rays) arise (radiation exposure and contamination) by long or intense radiation (eg. as solarium) by other ultraviolet radiation sources, by exposure to X-rays or other non-solar sources. Burns, by strong acids, strong bases (z. B. liquor, cement), phenols, cresols, mustard gas, phosphorus, and certain petroleum products (eg., Gasoline, turpentine) are caused. The necrosis caused by these agents of the skin and deeper tissues may still continue for several hours. Electrical burns are the result of the heat generation and electroporation of cell membranes in connection with strong electric current. Electrical burns often cause extensive deep tissue damage to electrically conductive tissue such as muscles, nerves and blood vessels, despite only minimal detectable cutaneous injuries. The costs associated with the combustion conditions (eg. As a jump from a burning building struck by flying debris, the collision of motor vehicles) can cause additional injuries. Abuse should be considered in young children and elderly patients with burns into consideration. Smoke inhalation burns and smoke inhalation often occur together, but can also occur separately. When smoke is inhaled, the toxic combustion products violate the nasal mucous membranes. Hot smoke only burns the throat usually because the inflowing gas cools quickly. An exception is steam that has much more heat energy than smoke and thus the lower respiratory tract can burn (below the glottis). Many toxic chemicals that are commonly produced in house fires (z. B. hydrogen chloride, phosgene, sulfur dioxide, toxic aldehydes, ammonia), cause chemical burns. Some toxic combustion products such as carbon monoxide or cyanidin affect the system Siche cellular respiration. Injuries of the upper respiratory tract usually cause symptoms within minutes, but sometimes only after several hours; Edema of the upper respiratory tract can cause stridor. Damage to the lower respiratory tract may also be associated with injuries to the upper respiratory tract and usually causes symptoms such. B. Problems in the oxygen supply by the increase in oxygen consumption or by a decrease in lung compliance within 24 h or later. Smoke poisoning is suspected in patients who have respiratory symptoms or carbonaceous sputum or if they were previously trapped in a burning environment. Perioral burns and singed nose hair can also be signs. The diagnosis of a violation of the upper respiratory tract is provided by an endoscopy (laryngoscopy or bronchoscopy) sufficient to represent the upper respiratory tract and trachea, and is able to detect edema, tissue damage, and carbon black in the respiratory tract. Occasionally, however, injury develop after the initial investigation. Endoscopy is performed so as soon as possible, usually with a flexible fiber optic, usually after or simultaneously with an endotracheal intubation in patients with significant findings. The diagnosis of a violation of the lower respiratory tract is provided by a chest X-ray and pulse oximetry or ABGA; Abnormalities may develop, or a few days later at once. Cyanides and carbon monoxide toxicity should be reviewed; the Carboxyhämoglobinspiegel be measured in patients with significant smoke inhalation. All patients at risk of smoke inhalation than First 100% oxygen through a face mask. Patients with airway obstruction or respiratory distress requiring intubation or other types of mechanical ventilation. Patients with edema or serious soot into the upper airways intubation as soon as possible because it is increasingly difficult quickly to intubate the airway when the edema increase. A bronchoscopy is usually done at the same time as the intubation. Patients with injuries to the lower respiratory tract require additional oxygen, bronchodilators and other supportive measures. Pathophysiology burns cause protein denaturation and therefore coagulation necrosis. encamp around the coagulated, burned tissue around platelets to blood vessels constrict, and poor circulation tissue (known as the stagnation zone) can die to the injury around. In the stagnation zone, the fabric is congested and inflamed. Damage to the normal epidermal barrier allows the invasion of bacteria and an external fluid loss; damaged tissue is often edematous, resulting in the loss of volume increases. The heat loss can be significant because the thermoregulation of the damaged skin lacks, especially in exposed wounds. Combustion depth burns first degree burns are limited to the epidermis. In 2nd degree burns part of the dermis is included and can be superficial or deep. Superficial 2nd degree burns affect the papillary (superficial) dermis. These burns heal within 1-2 weeks, and scarring is usually minimal. The healing occurs from the epidermal cells that border the sweat ducts and hair follicles. These cells migrate towards the surface and then spread to abut on the surface, on cells of adjacent glands and follicles. Deep 2nd degree burns affect the deeper dermis and need ? 2 weeks to heal. A healing begins only from the hair follicles. Scarring is common and can be severe. 3rd degree burns involve the entire thickness of the dermis and go up into the underlying fat layer. The healing takes place only from the periphery; these burns, except for small burns, excision and skin grafting should be performed.
