Methods of local antimicrobic prophylaxis of surgical site infection

Abstract

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.
