Abstract
Objective:To explore the common pathogenic bacteria of lung infection,the infection related factors and percentage so as to provide direction of prevention and therapy.Method:The sputum samples of 316 patients with pulmonary infection were cultured and given drug sensitivity test,along with analyzing infection-related factors.Result:The positive proportion of sputum culture were 41.77%,including Gram-negative bacteria(49.24%),fungi(40.91%)and gram-positive bacteria(9.84%). In the factors of close-related with pulmonary infection,using broad-spectrum antibiotic were 94(71.21%)cases,invasive operation were 34(25.75%)cases,abdomen and thoracic surgical operation were 24(18.18%) cases,using glucocorticoid and immunosuppressants were 13(9.84%)cases.Conclusion:The main pathogenic bacteria of pulmonary infection are gram-negative bacteria,followed by fungi and gram-positive bacteria. The below are the high percentage of pathogenic bacteria,such as Pseudomonas aeruginosa,Klebsiella pneumonia,Escherichia coli,Candida albican,Staphylococcus aureus. Using broad-spectrum antibiotics unreasonably and using immunosuppressants,invasive operation,low immunity caused by underlying diseases,thoracic and abdominal surgical operation are main causes and factors for pulmonary infection patients.关键词
