Abstract:
Objective To study the correlation factors in lower respiratory tract infections after tracheotomia in ICU. Methods 20 patients were accepted. We gathered the samples on skin of neck before tracheotomia, and gathered 12 samples on buccal cavity, professional jargon, pharyngeal portion secretion, sputum at lower respiratory tract, ward atmosphere, article surface, drainage tube, pipeline interface of breathing machine, humidification bottle, tracheostomy cannula and hands of nurse, respectively, at the first day, fifth day, tenth day and fifteenth day after tracheotomia. And then the relationship of kinds of factors and lower respiratory tract infection was analyzed by Chi-square criterion and Spearman rank correlation analysis of Stata 9.0 statistics software. Results The rate of lower respiratory tract infection was 95%, and the results were not same at indifferent times (P<0.01). Spearman rank correlation analysis showed that distribution of pathogenic bacteria in respiratory tract at different times had positive correlation with equipment pipeline, oral cavity, pharyngeal portion and incision of trachea, and had no obvious correlation with hands of nurse, ward atmosphere and article surface. Conclusions The patients after tracheotomia have an higher incidence rate on lower respiratory tract infection in ICU, especially within 10 days. lower respiratory tract infection after tracheotomia has close relationship with equipment pipeline, mainly such as ventilator, in addition to the patients' self-factors.
