老年社区获得性肺炎病原学分析及临床对策

目的:观察佛山市南海区老年社区获得性肺炎病原菌的分布情况,为经验性治疗提供依据。方法:对183例符合CAP诊断标准的患者留取痰标本进行细菌培养,采用血清方法监测非典型病原菌。结果:183例患者病原菌检测阳性共有92例,共获得致病菌117株,其中检测出单一病原菌感染为69例,2种混合感染21例,3种混合感染仅2例。结论:老年社区获得性肺炎的主要病原菌是肺炎链球菌,因此经验治疗应选用广谱抗生素,如新型喹诺酮类及第2、3代头孢菌素等疗效较好。

Etiological analysis and clinical therapy in gerontic Community acquired pneumonia

Objective:To study the distribution of gerontic community acquired pneumonia pathogens(CAP) in Nanhai District of Foshan City,to offer clinical evidence for experiential therapy.Methods: Sputum from 183 CAP cases was collected for bacterial culture,and to detect atypical pneumonia pathogen by serological method.Results: 92 cases were detected positive pathogens in 183 cases.From 117 strains of pathogenic bacteria,69 cases were detected to catch unite pneumonia pathogen,21 cases of two strains mixed infection and only 2 cases of three strains mixed infection.Conclusion: Archpathogen of acquired pneumonia pathogens(CAP) in gerontic community is streptococcus pneumoniae.Accordingly,broad-spectrum antibiotic could give better effect on acquired pneumonia pathogens in experiential therapy,such as neotype quinolones and cephalosporin of 2nd or 3rd generation.
