Abstract: Background. The issue of prevention and treatment of purulent-necrotic complications of diabetic foot syndrome is very relevant now. Despite the constant improvement of methods aimed at improving the results of treatment of purulent-necrotic complications in these patients and preventing their occurrence in general, their frequency remains at the same level. One of the factors affecting the wound process in patients with diabetes mellitus is the presence of oxidative stress in the area of the wound defect and in the perifocal zone. In conditions of diabetic angiopathy, the effectiveness of systemic pharmacotherapy is due to the impossibility of adequate delivery of drugs directly to the purulent-necrotic focus, which leads to the search for new methods of local treatment. Materials and methods. An experimental study of the effect of extracellular collagen matrix impregnated with antioxidants on the dynamics of oxidative stress in the conditions of wound process on 36 Wistar rats was carried out. An extracellular collagen matrix impregnated with ethylmethylhydroxypyridine succinate was implanted into the area of the created defect. The dynamics of the main indicators in the pro-oxidants-antioxidants system was evaluated on the 7th, 14th and 30th days after implantation. Results and conclusions. The animals of the main groups showed positive dynamics in restoring balance in the lipid peroxidation system. Thus, the use of antioxidants as part of the extracellular matrix and gel form makes it possible to neutralize the phenomena of oxidative stress in a shorter time.
