目的 :了解老年人医院获得性下呼吸道感染的病原菌分布 ,耐药情况及易感因素。方法 :对 135例老年医院获得性下呼吸道感染作回顾性分析。结果 :G-杆菌占 6 9.1% ,其中以铜绿假单胞菌 ,大肠杆菌 ,不动杆菌 ,克雷伯杆菌为主 ;G+ 球菌占 2 2 .1% ,以金黄色葡萄球菌 ,表皮葡萄球菌 ,肠球菌为主。大部分G-杆菌对亚胺培南 ,头孢他啶 ,头孢吡肟 ,哌拉西林 /三唑巴坦 ,阿米卡星较敏感 ,全部G+ 球菌对万古霉索敏感。抵抗力低下病人 ,住院时间长 ,感染发病率高。结论 :掌握细菌耐药新动态 ,合理使用抗生素 ,缩短住院日期 ,减少感染发病率。
Objective: To understand the distribution of pathogenic bacteria, drug resistance and susceptibility to acquired lower respiratory tract infection in the elderly. Methods: Retrospective analysis of 135 cases of lower respiratory tract infection in elderly hospital. Results: G-bacilli accounted for 6 9.1%, of which, Pseudomonas aeruginosa, Escherichia coli, Acinetobacter and Klebsiella were the main types; G + bacteria accounted for 21.2%, Staphylococcus aureus, Staphylococcus epidermidis , Enterococcus-based. Most of the G-bacilli were sensitive to imipenem, ceftazidime, cefepime, piperacillin / tazobactam and amikacin, and all G + cocci were sensitive to vancomycin. Low resistance patients, hospitalization for a long time, the high incidence of infection. Conclusion: Grasp the new trend of bacterial resistance, rational use of antibiotics, shorten the hospital date, reduce the incidence of infection.
