[The use of lasers in treating soft-tissue suppurative-inflammatory diseases]

The authors have established in vitro, that helium-neon (HN) laser rays at the therapeutic doses had no bactericidal effect. Bactericidal effect of the rays of an ultraviolet (UV) laser is manifested in exposure for 5 min (output power of 3 mW, pulse frequency of 100 Hz, diameter of the irradiated area of 3 mm). In the clinic, a combined method with the use of HN-laser with radiant power of 20 J/cm2 and UV laser with radiant power of 7 J/cm2 was employed. Duration of treatment of purulent-inflammatory diseases reduced 2-5-fold as compared with that in use of conventional methods of treatment.
