Recently, to prevent of surgical site infection, new methods of local antimicrobic prophylaxis have been developed and successfully introduced, which allow to creating high concentrations of antimicrobial drugs in operated tissues and preventing the migration of bacterial flora into the wound. The review describes the main methods used for local impact on microflora and aimed at prophylaxis of surgical site infection. The latter include pre-, intra- and postoperative measures. Optimizing of preoperational methods could be achieved by improving the methods of processing of operating field. Reviews considerable attention is paid to intraoperative measures: the use of surgical gloves with antimicrobial properties, reticulated to implants with antimicrobial properties for tension-free hernioplasty, stage-by-stage surgical wound irrigation with antibacterial drugs during suturing as well as the prospects for the use of bacteriophages in abdominal surgery. To increase the biological tightness of the intestinal suture, some authors propose the use of a biodegradable antibiotic-impregnated implant. The review reflects the possibilities of using biologically active (antimicrobial) sutures, the use of which was very effective at all stages of the operation: from the application of intestinal anastomosis to the skin suture. A wide range of antimicrobial surgical sutures containing antibacterial preparations and made by threads with different biodegradation abilities make, allow us to recommend a differentiated approach to the choice of suture material depending on the stage of surgery and regenerative properties of the sutured tissues. The main measures recommended in the early postoperative period are to cover the wound with special wound coatings preventing the possible contamination and to improve irrigation-aspiration drainage techniques of postoperative wounds.

The main method of joining the wound edges in surgery remains suturing with the help of threads. Unfortunately, suture materials used in surgery have a number of disadvantages. The percentage of postoperative wound complications remains high. One of these consequences is the failure of the seam, depending also on the material used in the operation. Suture material, as a genetically alien object, that is a foreign body, with a long stay in the tissues can lead to the development of complications: causes suppuration of wounds, formation of abscesses, peritonitis. Materials and methods: The analysis of modern Russian-language and foreign literature, also Internet sources devoted to the issue of issues and modern developments of antiseptic suture material. As a result, the choice and development of an ideal suture material that meets all the requirements, remains an unsolved and socially significant problem in surgery. Despite the variety of variations already offered, there is currently no suture material with antimicrobial activity on the market that would fully reduce the risk of developing infections in the surgical area. But the achievements of modern chemical production make it possible to develop biologically active suture materials that have the ability to resist the development of infectious complications in a wound and improve tissue regeneration without adversely affecting the body. In addition, the analysis showed an increased interest of developers to chitosan, due to its exceptional biocompatibility, bioresorbability, non-toxicity, antibacterial properties and hemostaticity.

Relevance: with the management of laparoscopic methods of surgical treatment of acute appendicitis, the problem of the occurrence of early postoperative complications has not changed at present, which makes it necessary to carry out preventive measures. Objective: to study the possibility of improving the results of surgical treatment of peritonitis, the most frequent complication of acute appendicitis, by reducing the number of postoperative complications of infectious genesis. Methods: Studies were performed on 47 non-linear white rats weighing 200-250 grams by modelling peritonitis using the biological model as an example, followed by antibiotic therapy and combination therapy using bacteriophages. To model peritonitis, the infection of the abdominal cavity with the E. coli strain 25922 was used. The laboratory animals were divided into 3 groups: the first group was control group, the second group received treatment in the form of a single intraperitoneal injection of Cefipime, the third group received treatment as a single intraperitoneal injection of the Sextapage. Results: the evaluation of the methods was carried out on the basis of the study of the clinical picture of the course of peritonitis in experimental animals, the data of pathomorphological and histological examination of the sectional peritoneum. As a result of experimental studies, there was no significant difference in the methods of perioperative prevention of complications of acute appendicitis, which makes it possible to perform monotherapy with bacteriophages. Phages in comparison with antibiotics have no less therapeutic efficacy. Conclusions: Thus, our experimental studies revealed completely satisfactory results of monotherapy of experimental peritonitis with a bacteriophage. According to the morphological data, the inflammatory process in the abdominal cavity is stopped by the phage fast enough and there is a tendency for a faster fading of the inflammation than in the treatment with antibiotics.

This study allows understanding the course of the process of tissue regeneration in the pathology of the nervous and endocrine systems. These systems are closely interconnected. The integrity of their pathogenic actions on the body is called neroendocrinopathies. They affect body tissues and especially the skin epithelium, independently causing dystrophies and changing their healing rate and regeneration of wounds received during the course of the disease. The wound healing rate depends on many factors, such as age, nutritional status and body weight, body immune status, and chronic comorbidities. The endocrine and nervous system disorders affect oxygenation, hormonal imbalance and nutrient supply of local tissues and the whole body. A wide range of diseases in humans, such as atopic dermatitis, psoriasis, herpes zoster, arthritis, diabetes is characterized by a distinct neurogenic and endocrine component. Micro- and macroangiopathy develops, carbohydrate metabolism in tissues suffers and immunity disorders occur. This disrupts the course of the wound healing process and slows down the recovery processes.
