![]() Grade 3b - damage to all elements of the skin, including accessory formations.This fact determines the possibility of independent healing of small-area burns due to granulation and marginal epithelialization from the surrounding healthy areas Only the deepest parts of it, in which the appendages of the skin (hair follicles and sebaceous glands) are laid, remain intact. Grade 3a - damage to the dermis, including the papillary layer.Small burns do not cause any burn disease hazards. The process of complete restoration of damaged tissues takes, on average, about two weeks. Grade 2 burns heal on their own, leaving behind reddened areas that eventually acquire a natural shade and do not stand out among healthy ones. The tissues in the affected area and adjacent areas are swollen. The victims are worried about burning pains that persist for several hours after receiving a burn. Their formation is possible due to the fact that the dead epidermis forms a cavity, which is filled with plasma (liquid part of blood) through expanded, partially altered microvessels. The surrounding skin may be reddened or unchanged. The clinical description of such a burn consists in the formation of bubbles of various sizes and areas, filled with a transparent straw-yellow liquid. Only their function is temporarily impaired with preserved pain sensitivity. Its significance lies in the fact that the bulk of the capillaries and nerve endings pass here, which forms the clinical manifestations of a 2nd degree burn. The epidermis and superficial areas of the dermis, up to the papillary layer, are destroyed. The main therapeutic struggle is being waged for her. ![]() By this time, there is a clear limitation of living and dead tissues, although the zone of microcirculatory disorders remains. ![]() It is possible to estimate the true volumes of the burn only the next day after receiving it. The second component is circulatory disorders in neighboring areas, which play a major role in aggravating the extent and area of damage over time.Ī characteristic feature of burn injuries is considered to be an increase in these indicators compared to the initial ones. The basis for the development of pathological changes and clinical manifestations of various degrees of burns is the direct destruction of skin elements by high temperatures. Its convenience and practicality are so obvious that even a person who is not familiar with medicine can easily understand it. This classification is unified all over the world and is used for almost all types of burns, regardless of the cause of their occurrence (thermal, chemical, radiation). In this case, cicatricial contractures are usually formed on the neck and in the area of the joints. On the site of deep burns, coarse scars are often formed, which, if burned to the face, neck and joints, lead to disfigurement. The dead tissue is partially melted and rejected within a few weeks. Healing, if an infection has joined the wound, occurs within ten to fifteen days without scarring.Ī third degree burn is the death of the skin with the formation of a gray or black scab.Ī burn of the 4th degree is necrosis and even charring of not only the skin, but also deeper tissues - muscles, tendons and even bones. Burn blisters are filled with a clear yellowish liquid, when they rupture, the bright red painful surface of the growth layer of the skin is exposed. Usually, recovery in these cases occurs on the fourth or fifth day.Ī 2nd degree burn is the appearance of blisters on the reddened skin, which may not form immediately. ![]() According to the depth of tissue damage, burns are divided into four degrees.Ī 1st degree burn is characterized by redness and slight swelling of the skin. ![]()
