Abstract Objective To analyze the distribution characteristics of respiratory tract pathogenic bacteria in patients with hypertensive cerebral hemorrhage undergoing tracheal intubation,so as to provide a basis for hospital infection work.Methods The clinical data of 588 patients with hypertensive cerebral hemorrhage who received endotracheal intubation assisted ventilation from January 2017 to December 2019 in Iron Coal General Hospital of Liaoning Health Industry Group were retrospectively analyzed.The patients took respiratory tract secretions for pathogenic analysis,and the pathogens with a quantitative culture concentration of≥107 CFU/ mL were designated as pathogens in the airway.Results There were 314 cases of respiratory tract nosocomial infection in 588 patients,the infection rate was 53.40%.During 3 years,2808 strains were cultured,among which Gram-positive bacteria (G+ bacteria) 422 strains (15.03%),Gram-negative bacteria (G- bacteria) 1854 strains (66.03%),527 strains (18.95%) of candida and 5 strains (0.18%) of others.Among the 422 strains of G+ bacteria,the most common was Staphylococcus aureus,with a total of 250 strains,and the trend was increasing year by year,followed by Staphylococcus hemolyticus and Staphylococcus epidermidis.Among the 1854 strains of G- bacteria,the most common was Pseudomonas aeruginosa,with a total of 545 strains,and the annual ratio was relatively stable,followed by Klebsiella pneumoniae,the proportion of which decreased year by year.Conclusion The hypertensive intracerebral hemorrhage patients undergoing tracheal intubation are a high-risk group of respiratory tract infections.It is important to analyze the etiological characteristics and accurately grasp their migration characteristics to effectively control nosocomial respiratory tract infections.
