[IMPACT OF THE WOUND COVERINGS ON THE WOUND PH IN SUPERFICIAL BURNS OF THE SKIN].

Impact of the wounds coverings on the wounds contents pH in the injured persons, suffering superficial burns of skin, was studied. In 75 patients (the main group) the wounds treatment was accomplished under the wounds covering, in 35 of them xenotransplants were applied, and in 40 ­ coverings made of hydrogel. In 35 patients (the comparison group) the moisture-drying gauze bandages were used. There was established, that the wound indices of pH constitute an important factor for the burn wounds healing. The changes of the media pH towards the acid one under the wounds covering had stimulated the wounds healing and epithelization.

[METABOLIC INTOXICATION IN THERMIC TRAUMA].

In 76 injured persons with deep and superficial burns, having area from 3 to 65% of the total body surface and ageing 5-16 yrs old, there was investigated the impact of early surgical treatment on the metabolic intoxication severity in accordance to content of the oxidatively modified proteins carbonyl groups in the blood serum, and of a ceruloplasmin, what was considered as integral express-index of the organism antioxidant system state. Changes of these indices in ambustial disease of middle severity have witnessed a sufficiently compensated reaction of organism: of severe and extremely severe one--there were noted a deficiency of the organism antioxidant defense; and in stages of toxemia and septicotoxemia--attrition of the organism oxidant reserves and danger of the septic complications occurrence. Conduction of early surgical intervention have guaranteed maintenance of a ceruloplasmin content in stages of toxemia and septicotoxemia on the level of healthy persons, relief of the ambustial disease course, absence of critical metabolic intoxication and carbonyl stress, reduction of the septic complications rate in 1.5 times.

[Studying of cytokine dynamics in injured persons with severe burns for estimation of severity and prognosis].

Dynamics of a blood serum concentration of tumor necrosis factor-alpha (TNF- alpha), interleukines (IL-1beta, IL-10) in 35 patients, suffering severe burn, and possibility of application of these indices as biomarkers of the severity state and the complications prognosis, were studied. During the investigation there was established, that TNF-alpha concentration on the 8 - 10th and 19 - 21th day after trauma does the best for characterization of a burn total area, while the IL-1beta concentration on the 8 - 10th day after trauma - the deep affections severity and the IL-10 concentration on the 19 - 21th day after trauma - the deep affections severity. Hyperreactivity, caused by enhanced production of TNF-alpha, IL-1beta and IL-10, witnesses the raised risk of development of the organs complications. And adversely, hypo- and areactivity in extended and deep burns witnesses about enhanced risk of lethality. The blood serum concentration of TNF-alpha, IL-1beta and IL-10 is expedient to use as a biomarkers of the patients state severity and for the course prognosis of pathological process.

[Tactics of treatment for extended burns of various affection depth].

Investigation was based on analysis of the treatment results of 75 children, suffering extended superficial and deep skin burns squared 15-30% of body surface. There was proved, that sequence of excision of superficial and deep necrotic scab influences the burn disease course. There was elaborated algorithm of sequence of the operative treatment stages in patients, suffering extended superficial skin burns, coexisting with deep burns, the superficial necrotic scab definitely, was excised after trauma and a deep one--in the second stage. The superficial and deep necrotic scab excision before 7-9th day after trauma have promoted significant reduction of the intoxication syndrome severity, the middle molecular mass peptides, indices of peroxidal oxidization of lipids, oxidizing modification of proteins, clinical signs of SIRS, rate of septic complications in 1.75 times, the stationary treatment time of severely ill patients by (7.2 +/- 1.5) days.
