| Summary: | Introduction: At the hospital, it was considered to know the incidence of infectious strains in BAS and in peritraqueostoma cultures in patients with tracheotomy tube. Material and methods: For two years, samples of bronchial and peritraqueostoma secretions of patients with tracheotomy tube were gathered at the moment of tube change. These data were processed according to standard procedures of the Microbiology Service at the Hospital Nacional Parapléjicos (Toledo). The study was carried out from March, 2008 to October, 2010. Outcomes: During the study period, 706 BAS´s and peritraqueostoma samples were processed, with a positive result in 93.77% and 82.15% respectively, and 813 microorganisms were isolated. Discusion: In our hospital, only 6.23% of the cultures BAS and 17.85 % of the peritraqueostoma cultures are negative. Pseudomonas Aeruginosa and Candida Albicans have turned out to be important agents of nosocominal infection in patients with tracheotomy tube, as they are present in 25.95 % and 18.45%, respectively, of microbiological strains from such patients. Discussion: In order to prevent nosocomial infections in patients with tracheotomy tube, it is very important to extreme hygienic measures at tracheotomy tube changes procedures.
