In most cases, the temperature rises, the processes of epithelization go slowly. Because of the increased blood supply of tissues on the face, the probability of joining a purulent infection is high. A third-degree face burn always heals very hard, since the damaged skin is necrotic and subsequently rejected.Toxemia in most cases is found in the victims with burns of 3 degrees, which occupy an area of more than 5% of the skin surface. The main sign of this state is the increase in temperature - up to 38-39 ° C: in this case, the higher the temperature, the less favorable it should be considered the forecast. The temperature at the third degree burn may indicate the development of toxemia, a pathological condition caused by intoxication of the body with residual products of protein decomposition and toxins entering the bloodstream from damaged tissues.Simultaneously with the increase in edema in the tissues, an inflammatory reaction develops, which does not allow the swelling structures to recover. Visually, edema in the third degree burn is a small tumor (swelling of the skin) with characteristic redness. In itself, edema is the result of accumulation in the skin layers of excess fluid - the effusion of damaged blood supply vessels. Edema in the third degree burn is a natural reaction of the body to traumatic damaging effects, with a violation of the integrity of tissues and the vasculature.The entire epidermal layer undergoes trauma, up to partial damage to the dermis.Ī dry or malleable burn cortex is formed of a gray or brownish hue.ĭamage affects the entire epidermal layer, the dermis, up to partial damage to the hypodermis.įormation of compacted dry scab of a brownish hue is observed. It is pointless to count on an independent healing of such a wound. Such a burn is not always accompanied by pain, due to damage to the pain receptors. Visually attract the attention of large-sized blisters containing fluid and blood elements. Degree 3-b - burn injury extends to all underlying tissues, including the subcutaneous fat layer.Without medical assistance, such a wound heals slowly and problematically. After a burn of degree 3a, a crust of grayish or brownish hue is formed, with the preliminary appearance of different sizes of bubbles with liquid. There is a necrosis of tissues against the background of vascular damage and local edema. Degree 3-a - is characterized not only by the epidermal layer, but also by a separate part of the hair follicles, sweat and sebaceous glands.As a consequence of this process, the wound surface is quickly filled with proteins and serum elements, which visually manifests itself in the form of an increasing edema.īurn 3 degrees are divided into two versions of the flow, depending on the pathogenetic and clinical features: In tissues that have been burned, vascular permeability is expressed. At the initial stage, vasoconstriction develops, which quickly passes to the dilatation stage. The lesion in most cases is dry, compact, painless, not prone to self-healing.Ī significant role in the pathogenesis of a burn is played by an inflammatory process that occurs in response to traumatic injury. Wound surface with a burn of grade 3 is usually a complete destruction of the epidermal layer, dermis and skin appendages. In this case, the degree of damage may differ, depending on the duration of exposure, on the temperature index, on the density of the skin at the lesion site, and on the quality of tissue conductivity. The impact of the damaging factor leads to the complete or partial destruction of cells and the violation of their functionality. non-observance of the rules for storage of chemical solutions, acids and caustic alkalis.non-observance of safety rules in the kitchen while cooking.The most common risk factors that can lead to a third degree burn are: The chemical type of burn is always caused by chemical preparations and concentrates, with the content of acids or caustic alkali.Įlectric burn can be obtained from current, after short-term contact with conductive elements.įrom accidental burn, as they say, no one is insured - the trauma can be obtained at home (for example, in the kitchen) and at work. Thermal burn can be the result of direct exposure to fire, boiling liquid or steam, as well as direct contact with incandescent objects. under the influence of a large dose of radiation.under the influence of an electric current.after exposure to aggressive-irritating chemical fluids. A third degree burn can occur for a number of reasons:
