Characteristic of respiratory ways mucosa microflora in patients with cicatrical stenoses of larynx and trachea

Abstract

The authors defined microbial landscape of mucous membranes of nose, oropharynx and trachea in patients with chronic cicatrical stenoses of larynx and trachea. 42 patients with tracheostomy have been examined. It was revealed that the growth of microorganism had been observed in 95–99% of cases, mainly in the monoculture. There predominated two-component associations. The main microorganisms supporting inflammatory reaction in trachea are Staphylococcus aureus, Group D Streptococcus, gram-negative bacilli. Tracheal mucosa microflora corresponded to the nasal cavity and pharynx biocenosis, hence it can be concluded that the tracheal mucosa seeding occurs from the upper regions of respiratory tract with the secretion aspiration from the nasal cavity and pharynx. Therefore, comprehensive care of the nasal cavity and pharynx in intensive care patient is essential for prevention of cicatricial process in the larynx and trachea to prevent aspiration of the discharge thereof in the lower respiratory tract.
