Results of endoscopic diagnostics and treatment of 58 victims with chemical burns of airways are reported. They made 16.9% of observations of all patients admitted to hospital with poisonings by cauterizing substances. Endoscopic and X-ray semiotics of airways chemical burns is reported. The incidence and severity of airways lesions in relation to the degree of esophagus chemical burns were assessed. It is established that burn laryngotracheo bronchitis became complicated by the development of pneumonia in 77.6% of observations , and in 6.9% by cicatricial narrowing of the trachea and bronchi. Localization and the development speed of infiltrative changes in lungs allow to assume that the aspiration of cauterizing liquids plays the key role in the pneumonia genesis. The therapeutic bronchoscopy included toilet bronchoscopy of the trachea bronchial tree with 0.01% solution of dioxydin and laser photo stimulation with a red- range low-energy laser. Therapeutic sessions were carried out 3 times a week. From 1 to 10 sessions were performed depending on the severity of airways chemical burns. Convalescence of all patients was achieved.
Electron temperature measurement of low-energy laser produced plasma using iso-electronic x-ray spectroscopy
