RESUMO
Objective With density in healthy people pharyngeal flora of the reference[1],study the respiratory tract infection and the treatment process of the change of density and pharyngeal flora infection treatment of correlation analysis,by using the density of the pharyngeal flora changes to evaluate the treatment of patients with respiratory tract infection and progno-sis.Methods Collected 102 cases of patients with upper respiratory tract infection and 219 cases of lower respiratory tract infection in patients with pharyngeal swab for bacterial culture,study clinical symptom change with the change of pharyngeal bacteria density of correlation.Results 62 cases of upper respiratory tract infection and the treatment group patients with pharyngeal flora normal no treatment group on the symptoms improved and recovered,no statistical difference (P >0.05), and 60 patients with upper respiratory tract infection and pharyngeal abnormal bacterium group the treatment group and treatment group in pharyngeal flora and CPIS score was statistically difference (P <0.05).For 219 patients with lower re-spiratory tract,including 121 cases of bacterial pneumonia,74 cases of severe pneumonia,and 24 cases of patients with lung abscess treatment observation,found that when back to normal pharyngeal flora,the accuracy of clinical pathological changes were 92.6%,86.5% and 87.5%,respectively.Conclmion Pharyngeal bacteria density between healthy people maintained a certain bacteria species and the number of stable,but when respiratory infections bacteria can disorders with the application of broad-spectrum antibiotics can lead to serious result in pharyngeal dysbacteriosis should be combined with pharyngeal bacteria in respiratory anti-infection treatment density changes to evaluate the clinical treatment,can reduce the number of days with antibiotics,patients with avoid induce drug-resistant bacteria and respiratory dysbacteriosis.
