[Clinico-morphological analysis of the results of endobronchial use of helium-neon laser in the treatment of chronic pneumonia in children].

Abstract

In treatment of children with chronic pneumonia by 3-5 bronchoscopic cleansing procedures with endobronchial irradiation of the mucosa with a helium-neon laser beam the highest effect is produced by a dose of 15 mWt/cm2 and 2 minute exposure. Regression is stabler and occurs more rapidly in patients with moderate deformity of the bronchial tree. The mechanisms of the therapeutic effect of the method is explained by normalization of microcirculation, intensification of epithelial proliferation and biosynthetic activity which create favorable conditions for induction of reparative processes in the bronchial mucosa.
