摘要
目的分析唐山农村地区老年社区获得性肺炎(CAP)住院患者病原学构成并初步分析合并常见基础疾病的病原体构成。方法选择在唐山市3家三级医院住院的唐山市农村地区老年CAP住院患者359例,分析患者痰培养结果,病原学构成,同时分析合并有常见基础疾病的老年CAP患者的病原学特点。结果 359例老年CAP住院治疗患者中,以革兰氏阴性细菌感染占72.9%,伴COPD、脑血管后遗症、糖尿病的老年CAP患者最常见为肺炎克雷伯杆菌感染,支扩中最常见病原体为铜绿假单胞菌。结论老年CAP住院患者以革兰氏阴性菌感染为主,其伴随的基础疾病影响病原学结果。
Objective To analyze the etiology of elderly hospitalized patients with comnmnity-acquired pneumonia in Tangshan rural area. Methods The sputum of 359 elderly hospitalized patients with community-acquired pneumonia was cultured to analyze the eti- ology features. At the same time, the etiology features of the patients complicated with common basic diseases were also analyzed. Results The most common bacteria of 359 elderly patients with CAP was gram-negative bacteria accounting for 72.9%. Klebsiella bacillus was commonly found in the CAP patients complicated with COPD, cerebrovascular sequela and diabetes, and Pseudomonas aeruginosa was the most common pathogen in elderly CAP patients complicated with bronchiectasis. Conclusion The most common etiology feature is gram- negative bacteria infection in elderly hospitalized patients with community-acquired pneumonia, and the features could be changed by the patients＇ complications.
