目的:探讨老年呼吸重症患者院内感染的原因。方法:对我院2010年3月~2012年6月收治的80例院内感染的老年呼吸重症患者的临床资料进行回顾性分析。结果:80例患者院内感染的主要原因是受菌体感染,从80例患者的520例标本中分离出150株病原菌。其中革兰氏阴性菌占64.2%,以鲍曼氏不动杆菌为主;革兰氏阳性菌占20.7%,以金黄色葡萄球菌为主;真菌占15.1%,以白色假丝酵母菌为主。病原菌主要存在于呼吸道与泌尿道。结论:老年呼吸重症患者院内感染的原因主要是感染了病原体,最大一类是多存在于呼吸道的革兰氏阴性菌。
Objective: To investigate the causes of nosocomial infections in elderly respiratory patients. Methods: A retrospective analysis was performed on the clinical data of 80 elderly patients with severe respiratory infections who were hospitalized from March 2010 to June 2012 in our hospital. Results: The main reason of nosocomial infection in 80 patients was bacterial infection. 150 pathogens were isolated from 520 samples of 80 patients. Among them, Gram-negative bacteria accounted for 64.2%, mainly Acinetobacter baumannii; Gram-positive bacteria accounted for 20.7%, mainly Staphylococcus aureus; fungi accounted for 15.1%, mainly to Candida albicans . Pathogens are mainly found in the respiratory tract and urinary tract. Conclusion: The main causes of nosocomial infections in elderly patients with severe respiratory infection are pathogens. The largest category is Gram-negative bacteria that are mostly present in the respiratory tract.
