Inkjet Oxygen-Sorption Treatment in Local Treatment Purulent Soft Tissue Wounds

Abstract

Relevance. Traditional treatment of septic wounds of soft tissues often leads to the development of complications, causing more than 30% of deaths after surgery. The oxidative and bacterial components have a key role in the pathogenesis of septic processes. The aim of the study was to develop a method of treatment of septic wounds, based on a combination of jet technologies, oxygenation and sorption therapy, and also to study the effectiveness of its use. Materials and methods. Studies were conducted on 120 white Wistar rats with septic wounds of soft tissue. There were 4 groups: 3 control and 1 experimental. There was no treatment in the 1st control group. Bandages and treatment of the wound with oxygen flow were performed in the 2nd control group. In the 3rd control group, bandages were performed, and the sorbent was applied to the wound surface. In the experimental group, in addition to dressings, jet oxygen-sorption treatment of the wound surface was carried out. The study of the effectiveness of the method was carried out using objective, histological, histochemical, bacteriological and statistical methods. Result. During the jet oxygen-sorption treatment of the wound surface, the disappearance of hyperemia was noted by 23.1%, the end of necrolysis - by 25.7%, the appearance of granulation - by 24.3%, wound epithelization - by 17.0% faster, compared with the data of the 1st control group. Conclusion. Use of the method the jet oxygen-sorption treatment for the treatment of septic wounds of soft tissues reduced the wound area by 1 day by 4.8%, 3 day by 6.7%, to 7-days 19.1% and to 10-day 43.9% compared to the 3rd control group.
