目的:探讨高龄患者之铜绿假单胞菌感染肺部的近况及其应对。方法:回顾性分析本院2011年9月-2014年9月发生的56例高龄铜绿假单胞菌肺部感染的病历。结果:在56例高龄铜绿假单胞菌肺部感染中肺炎(院内获得性)占83.9%(47/56),药敏试验表明铜绿假单胞菌耐药率高,死亡率达16.1%(9/56)。易感因素有:住院时间长、高龄、机械通气、免疫功能低下、患有COPD、长期广泛的经验性应用广谱抗生素。结论:铜绿假单胞菌肺部感染是医院获得性肺炎最常见的一种,细菌耐药发生率高,病死率高。
Objective: To investigate the status of pulmonary infection in elderly patients with Pseudomonas aeruginosa and its response. Methods: The clinical records of 56 cases of Pseudomonas aeruginosa pulmonary infection in our hospital from September 2011 to September 2014 were analyzed retrospectively. Results: Pneumonia (acquired in hospital) accounted for 83.9% (47/56) in 56 cases of Pseudomonas aeruginosa pulmonary infection. Susceptibility tests showed that the drug resistance rate of Pseudomonas aeruginosa was high, with a mortality rate of 16.1% 9/56). Susceptible factors are: long hospital stay, advanced age, mechanical ventilation, immunocompromised, with COPD, long-term broad-based empirical application of broad-spectrum antibiotics. Conclusion: Pseudomonas aeruginosa pulmonary infection is the most common form of hospital-acquired pneumonia. The incidence of bacterial resistance is high and the case fatality rate is high.
