[Combined use of various laser radiations in thoracic surgery in experimental studies].

The impact of various types of low-intensive lasers (He-Ne, copper vapour, ultraviolet, infrared, infrared gallium arsenide) on healing of a wound made by CO2 laser at an output power of 25 W was studied in an experiment on 120 albino Wistar rats. It was found that a concurrent application of high- and low-intensive lasers resulted in acceleration of reparative processes in the lung, stimulating the healing of laser-induced wounds. The infrared gallium arsenide laser was demonstrated to be the best tool in stimulating the healing process.
