老年护理病房肺部感染菌群及耐药性分析

目的了解老年护理病房患者肺部感染的菌群分布及耐药性，为临床治疗提供依据。方法回顾性分析我院老年护理病房住院患者中132例肺部感染患者的菌群分布和药敏结果。结果共收集致病菌118株，其中革兰氏阴性杆菌96株（81．36％），革兰氏阳性球菌16株（13．56％），真菌6株（5．08％）。革兰氏阴性杆菌中肺炎克雷伯均检出率最高（57株，59．37％），革兰氏阳性球菌以金黄色葡萄球菌最多见（9株，56．25％）。药敏结果显示革兰氏阴性杆菌对亚安培南一西司他汀的耐药率低，其次为氨基糖甙类抗生素；革兰氏阳性球菌对万古霉素耐药率低。结论革兰氏阴性杆菌是老年护理病房患者肺部感染的主要病原菌，应依据痰细菌培养和药敏结果选用敏感抗生素。

pulmonary infection and drug resistance of bacteria in the aged nursing wards

Objective To learn flora distribution and drug resistance of pulmonary infection among the patients in the aged care wards, provide the basis for clinical treatment. Methods Flora distribution and drug susceptibility were studied by a retrospective analysis among 132 hospitalized patients who diagnosed lung infection in the aged nursing wards. Results 118 pathogens were collected and isolated, gram - negative bacilli infection was 96 strains （ 81.36% ）, gram - positive cocci was 16 strains （ 13.56% ） , fungi was 6 strains （ 5. 08% ）. The detection rate of klebsiella pneumoniae was highest of 57 strains（59.37% ）in the gram -negative bacilli, Staphylococcus aureus was the most common of 9 strains（ 56. 25% ） in the gram - positive cocci. Gram - negative bacilli susceptibility results showed the resistance rate to imipenem and cilas- tatin sodium was low, followed by aminoglycoside antibiotics ; Gram - positive cocci was low resistance to vancomy- cin. Conclusion Gram - negative bacilli is the main pathogen in patients with pulmonary infection aged nursing wards. Sensitive antibiotics should be selected based on sputum bacterial culture and sensitivity results.
