摘要
目的调查分析老年肺炎的危险因素、病原学特点及临床特征。方法收集2005年1月至2009年3月呼吸内科住院的72例老年肺炎患者病例,统计并分析其临床特点及细菌培养结果。结果本组资料显示大部分患者有基础疾病及易感因素,临床表现不典型;共检出病原菌108株,其中革兰阴性杆菌63株(58.3%);混合感染35例,占48.6%,二重感染13例,占18.1%。结论提高对老年肺炎的诊断率,根据其病原学特征合理使用抗生素,并建议对老年肺炎患者采用降阶梯疗法,以提高治愈率。
Objective To investigate the risk factors,etiological characterization and clinical feature of aged pneumonia.Method Total 72 cases of aged pneumonia from Jan 2005 to Mar 2009 were collected and analyzed.Result Most patients had underlying diseases and susceptible factors without typical clinical symptoms and signs.Total 108 pathogens were isolated,among which there were 63 strains of Gram-negative bacilli（58.3%）.There were 35 cases of polyinfections（48.6%） and 13 cases of double infections（18.1%）.Conclusion The diagnosis of aged pneumonia should be improved and antibiotics be used rationally according to the characterization of pathogens.Empiric treatment with broad-antibacterials or antibacterial combination should be considered.
