Nowadays, the various techniques of thermal energy are applied for dissection and coagulation of biological tissues in surgery. The plasma surgery technology is on of the leading one among them. Multiple publications concerning application of plasma flows testify the following advantages: bloodless dissection of tissues, hemostasis and sterilization of wound surface, making of optimal conditions for subsequent regeneration of tissue substrate, especially due to stimulating effect of molecules of exogenous nitrogen oxide (II) of air plasma jet. On the basis of publication data, the analysis is applied to efficiency of the given technology, features of plasma physical effect in various regimen, possibilities of combined application of this technology with other physical chemical methods. The article presents in details historical aspects of development of plasma technology in Russia, types of plasma installations, specific thermal alterations of organs and tissues after plasma processing in surgical regimen. The method was successfully approved in abdominal and thoracic surgery, operative gynecology, stomatology and oncology. However, plasma technology is mostly called-for in contaminated surgery. This technology, in combination with surgical processing, provides efficient elimination of necrotizing masses and pathogenic flora; thorough hemostasis with formation of mechanically isolating scab as a barrier for in-hospital infection. The fast settlement of inflammatory occurrences in the very wound and in tissues of para-vulnar zone and also stimulating effect on regeneration processes testify positive effect of sanation with various plasma flows in treatment regimen.
