社区获得性肺炎指在医院外罹患的感染性肺实质炎症,是具有明确潜伏期的病原体感染在入院后平均潜伏期内发病的肺炎。老年人气道的防御功能减退、黏膜纤毛的清除功能降低,又常合并存在多种疾病,更易发生社区获得性肺炎。老年人临床表现往往不典型,且多见混合感染,病情变化快,肺炎死亡率较青年患者更高,所以早期诊断、及时治疗非常重要。
Community-acquired pneumonia refers to infectious pulmonary parenchymal inflammation that occurs outside the hospital and is a pathogenic pneumonia that has a definite latent period of infection that develops during the mean incubation period after admission. Decreased defense function of the elderly airways, mucosal ciliary clearance decreased, often combined with a variety of diseases, more prone to community-acquired pneumonia. Clinical manifestations of the elderly are often atypical, and more common mixed infection, the disease changes rapidly, pneumonia mortality rate higher than younger patients, so early diagnosis and timely treatment is very important.
