Burns

Scalds are more uniform in character than flame burns. Young children often have burns in the fall in the container with hot water, roll-over on itself utensils with hot food. Very dangerous burns hot liquid food (soup, soup, etc.), because they are high in fat and have a greater thermal conductivity. Burns ferry also have their differences (in particular - overheated steam under pressure) and may be accompanied by TIT. Contact burns result from contact with the skin, hot objects (hot solid metal, iron, stone, molten metals, etc.). They occur in 10% cases of burns. Most often they are small in size, deep (IV cent.), And uniform.

In the pathogenesis of coagulation proteins, not only the skin but also the underlying tissues, vascular thrombosis (hence - a significant ischemia, which leads to deep tissue necrosis, a large area paranecrosis). Proteins can be denatured epidermis at 50-60o (so you can get burned even with prolonged use of medical heaters). Burns arise when contact with burning fats, oils, viscous combustible materials (plastics, resins, tar or asphalt). They do usually take the form of patches, small in depth (usually II-III century.) And the area (because these substances are not spreading over the surface of the skin and not absorbed through the skin). But viscous flammable substances stick to the burned skin.

Distant thermal burns - arise when applied to the skin and mucous membranes of harmful radiation heat, ultraviolet and visible spectrum, with no contact with hot objects, bodies. They are: sunburn, burns from electric arc flash, from the apparatus for welding, infrared devices from which usually superficial, due to the very short-term effect of the flash (low exposure), although this may be the ignition of clothing and a deep, widespread burns. As a result, the influence of bright light that occurs in electric arc may be in the form of defeat keratitis, cataracts, horioidita, optic nerve atrophy.
