Experimental Substantiation of Application Ozonized Physiological Solution in Surgical Treatment of Chronic Osteomyelitis

Abstract

Acute hematogenous osteomyelitis with inadequate treatment or no as such can become chronic. The latter involves a problem of not only increasing resistance of microorganisms to antibiotics (ABP), but their stable persistence in the body for a long time. Inability to achieve bactericidal concentrations of antibacterial drugs in the sequester due to lack of blood circulation in pyogenic foci makes inefficient traditional antimicrobial therapy. The purpose of this study - to justify the use of ozonated saline solution in the complex treatment of HGO through experimental research and development of optimal methods of influence on gram (+) and Gram (-) bacteria, fungi of the genus of Candida, Mycobacterium tuberculosis. We have carried out two series of experiments. To approximate the experimental conditions to the in vivo conditions of the surgical wound bacterial culture medium used - mylar fabric is hygroscopic and can largely mitigate the impact of aggressive antiseptic solutions to the CFU, simulating wall abscess (hereinafter referred to as the test object). One of a series of tubes with different concentrations of bacteria were exposed to ozonated saline with different exposures. The presence of colony growth test - bacteria on the test -object on the surface of the culture medium showed that ozone treatment for a given exposure time exposure did not provide a reliable germicidal effect. Lack of growth of colonies test - bacteria on test - and the object in a nutrient medium surface indicates the presence of bactericidal activity. The results of experimental studies have shown the high efficiency of ozonated saline against S. aureus ATCC 25923 with exposure 20 min., Ps. aeruginosa ATCC 27853 at 30 min exposure. In C. albicans strain 401 / 885-653 treatment ozonated saline solution has a bacteriostatic and pronounced inhibitory effect upon exposure of 30 minutes. This allows us to draw a conclusion on the appropriateness and effectiveness of the use of ozonated saline solution in the treatment of chronic hematogenous osteomyelitis of the spine.
