Diathermocoagulation is burning tissues alternating current of high frequency. The electrocoagulation is applied to stop bleeding in operations, removal of warts, some tumors of the skin, throat, treatment of cervical erosion, retinal detachment, inflammation of the pulp of the tooth, hyperplasia of gingival papilla. After being burned area of the body passed a current, allowing to heat the tissue up to the temperature at which reached irreversible clotting (coagulation) proteins. Inner and middle shell vascular walls shrink and wrap up in a lumen of the vessel; formed a blood clot, which leads to clogged arteries. This prevents bleeding and the possibility fall infection in the bloodstream. Coagulation nerves reduces post-operative pain. Very strong currents should not be used, as this coagulation and break the walls of the vessel may come before it manages to form a clot, and there is bleeding. In this case, re-coagulation you can begin only after a thorough drying of the surgical field.
There are two ways electrocoagulation: pseudounipolar and uaktywni. In the first case one electrode (passive) in the form of a lead plate placed on the lower back, while the second (active) in the form of needles, blades, ball - to be burning the skin or mucous membranes. When biactive the method is used the same two small adjacent electrodes.
Electrocoagulation is burning tissues electric current (constant or variable high frequency). The electrocoagulation DC produce special nozzles, heated to the desired temperature shock, the value of which is regulated by the rheostat. This deprecated method replaced by a more modern way - electromechanochemical. Cm. also Electrosurgical methods of treatment.
