N.E. Bauman MSTU have developed a new method for ultrasonic treatment of infected wounds, for which a patent of the Russian Federation was obtained [5]. This method is based on enhancing the cavitation effect of ultrasound on the bacterial microflora due to additional physical and chemical factors: low concentration antiseptics (0.1% hydrogen peroxide solution), excessive external static pressure (in the range of p = 0.05–0.15 MPa) and optimal temperature of sonicated solution in the range of 37–42°C).

The article presents the results of successful testing of the proposed method for ultrasonic bactericidal treatment. Tests have shown that the sonic treatment of open infected soft tissue wounds associated with a gunshot injury contributed to the rejection of necrotic tissues, the removal of fibrinous plaque, the development of full-fledged granulations, the formation of epithelial tissue and the reduction of the wound treatment period by 7-8 days.

The area of rational application of the method under consideration is the treatment of soft tissues after gunshot injuries, which are characterized by a complex topography of wound tracts, significant internal defects in biological tissues, as well as extensive microbial invasion.
