老年病科院内肺部感染细菌分布及耐药性分析

Geriatrics nosocomial pulmonary infection bacterial distribution and antibiotic resistance analysis

目的:分析老年病科院内获得性肺部感染的细菌的分布及其耐药性,为临床合理应用抗生素治疗提供依据。方法:对老年病科院内肺部感染的所有分离的细菌菌株、真菌菌株的耐药性进行调查。结果:医院获得性感染中仍以G-菌为主占73.3%,其次为G+菌17.9%,真菌8.7%。在细菌感染中,G-菌占80.3%,G+菌占19.7%。G-菌仍以铜绿假单胞菌为主,占21.7%。G+菌以金黄色葡萄球菌为主31.4%。耐药性方面,细菌耐药性严重,真菌耐药性较轻。结论:细菌对常用抗生素的耐药性严重,且呈多重耐药。应严格掌握抗生素使用原则,根据药敏选用抗生素。

Objective To analyze the Department of Geriatrics, acquired pulmonary infections of bacterial distribution and drug resistance, provide the basis for the clinical application of antibiotic treatment. Methods Geriatrics nosocomial pulmonary infection in the separation of bacterial strains, the resistance of fungal strains to investigate. Results G-bacteria mainly the results of hospital-acquired infections still accounted for 73.3%, fol-lowed by G+bacteria 17.9%, fungi 8.7%. In the bacterial infections, G-bacteria accounted for 80.3%of G+bacteria accounted for 19.7%. G-bacteria is still Pseudomonas aeruginosa, accounting for 21.7%. G+bacteria Staphylococ-cus aureus 31.4%. Drug resistance, bacterial resistance to serious fungal resistance lighter. Conclusions of bacte-rial resistance to commonly used antibiotics, and there was the multi-drug resistant. Should strictly adhere to the principle of the use of antibiotics, use of antibiotics based on susceptibility.
