[The first experience with the concurrent effect of YAG-neodymium and YAG-erbium laser on experimental animal tissues and the possibility of its use in surgery].

To guarantee the necessary rate of cutting live tissues with adequate hemostasis along the line of the incision, the authors studied isolated and joint effect of radiations of AIG-neodymium and AIG-erbium lasers on the tissues of laboratory animals. The possibility of accomplishing intraoperative hemostasis on the parenchymal organs was studied in experiments with AIG-neodymium laser. A good dissection effect in cutting various tissues was produced in the second series of experiments with AIG-erbium laser.

[Optimal parameters of carbon dioxide laser irradiation in the prevention and treatment of suppurative-inflammatory surgical diseases in children].

An analysis of experience with using the CO2 laser radiation with power density of 15-60 Wt/cm2 and 100 Wt/cm2 with the purpose in mind to prevent acute inflammatory complications and treat pyo-inflammatory surgical diseases in children. Results of microbiological and histological researches of the laser radiation studied are presented.

[Surgical debridement of wounds in children using CO2 laser].

Experience in the use of the CO2 laser beam in complex surgical debridement of primary traumatic wounds in 77 children showed that in a power density range of 15 to the Wt/cm2 it led to a sharp decrease of microbial dissemination in the wound and in 81.3% of cases to sterility of the wound surface. Carbon-dioxide laser radiation has an effect on the surface leucocytic-necrotic layer, replacing it with a narrow zone of thermal coagulation necrosis, and on the polymorphonuclear leucocytes lying in the thickness of the tissue of the wound wall at different depths.

[Use of carbon dioxide laser radiation in the treatment of wounds in children].

Results of treatment of 84 children with purulent and posttraumatic wounds with the help of CO2 laser are analyzed. The laser was used as a "surgical scalpel" and for necrectomy in suppurations. The focused and disfocused laser rays were used.
