APPLICATION OF COLD PLASMA COAGULATOR WHEN TREATING WOUNDS AND RETENTION CYSTS.
O. B. Baranov.
In veterinary practice retention cysts and wound of dogs and cats are not often met, but they are hard to treat with means of medicamentous treatment, and surgical operation is complicated because of difficulty of operative access. The cause of wound rising is enlargement of varton's and rivinious ducts of salivary glands as a result of thrombosis. In most cases its thrombosis is consequence of inflammatory process because of often traumatizing of mucous coat of oral cavity. Wounds appear more often on dogs than on cats, and they are situated between lower jaw and tongue, and after their cutting contents appear as dense, transparent and slimy liquid.
Methods of liquid exhaustion gives brief therapeutic effect. Later cavity of enlarged duct fills with secretion of salivary glands. With total wound ablation appear difficulties as a consequence of physiological feature of its location, because ablation of semi-capsule of enlarged duct is necessary. In the course of the operation numerous vessel ligature and sewage of defect of mucous coat of sublingual area of oral cavity are needed, which results in lack of flexibility of mucous coat and seriously limits tongue mobility.
When using Cold Plasmic Coagulator (CPC) cauterization of semi-capsule of wound without its exfoliation from adjacent tissues and later ablation were made. In the course of surgical operation wound edges were fixed with clips. After contents removal cyst was lanced and its edges were widely opened, easing access to the inner cavity. Inner surface was dried with plugs, then it was cauterized with CPC in the mode of tissue separation. Coagulating effect of CPC didn't let the wound to bleed and didn't traumatize tissue deeply. Suture for closing of defect of mucous coat of sublingual area wasn't needed, that is why tongue impellent function generally wasn't transgressed. Relapses appeared only in cases when the wound cavity was treated not completely, that could happen in case of very deep ducts damage.
When cauterizing with CPC small animals can have discomfort because of discrepancy of sizes of work-head and opening of oral cavity, i.e. when wound treatment is impossible (when they are situated too near to the tongue's root. One should remember that that when using CPC plasmic arc appears when needle approaches the object to 0.3-0.6 mm., that is why wound edges should be opened as wide as possible and slightly raise treated surface. It is recommended to use binocular glasses with autonomous directional light. Restoration of mucous coat of sublingual area better proceeded when vinylin and dog-rose oil were applied to it.
Conclusion. With retention cysts in submaxillary areas, similar to follicular inflammations, in the initial stage of their formation precise cauterizing is needed followed by oral cavity treatment with antiseptical solutions or tannin-containing solutions.
Device "Cold Plasmic Coagulator" (CPC) is developed on basis of up-to-date achievements of defense industry in the area of plasma devices, it has local coagulating and bactericide effects, and works from autonomic power source. Its first examples were created in 1994 by engineer of one of Russian Research Institutes Stanislav Avramenko. On this site science materials about CPC using in veterinary are presented. The results are drawn by his son, Constantine Avramenko (e-mail). Read his article about CPC…
Principle of operation of CPC is getting the cold plasmic beam. When coagulating with it in tissues treated there's no
much heat-evolution, that's why depth of thermal damage is about 0.1-0.2 mm. This gives possibility of wide using of this
device in veterinary, including ophthalmology. When treating the wound with CPC wound surface healing process is much
faster, than after treating the wound with other kinds of coagulator.
CPC is unidirectional, which allows to avoid current passing through tissue and their electrolysis as a consequence., which can be seen when using other kinds of coagulator. In CPC coagulation is made with plasmic beam, and electrode contact with treated surface lacks, that provides additional protection from infecting the wound.
