[Management of infected wounds and trophic ulcers by low frequency ultrasound]

The article is devoted to the investigation of the use of low frequency ultrasound surgical instrument in treatment of trophic ulcers and infected wounds in surgical patients. The method of treatment of these wounds and ulcers by cavitation influence through an intermediate medium was established, an ultrasound surgical apparatus "SUSA-2lf.02", being used, which has been developed and manufactured by AOZT "Medilen"--(St Petersburg). On the base of the experience in treatment of 76 patients intensification of diffusion of the medical preparations into the tissues was shown, among them--into the deep layers of the wound channel. The application of ultrasound provides favourable metabolic changes (normalization of pH of the medium), ensures deep diffusion of medicamentous preparations into the tissues surrounding the ulcers, and enhances therapeutic activity of the preparation.
