[Clinico-morphologic changes of the respiratory passages in cases of burns of them].

The authors examined the functional state of the respiratory apparatus in 343 patients with burns of the respiratory ways (BRW). The defensive, respiratory, conditioning and olfactory functions were investigated. It was established that lesions of the respiratory tract mucosa in BRW causes primarily severe disorders of the transport and secretory functions that further the development of bronchial obstruction and deteriorate pulmonary ventilation. Lesions of the respiratory tract mucosa in BRW are deep and should be equated with III AB grade burns. The course of he burn process in the respiratory ways plays a significant part in the pathogenesis of burn disease pneumonia. This should be considered in planning treatment of patients with BRW.
