摘要
目的探讨ICU老年患者院内下呼吸道感染病原菌的分布特点和耐药情况。方法回顾性分析67例ICU老年患者院内下呼吸道感染病原菌特点和耐药性。结果该组67例患者下呼吸道分泌物标本共培养出病原菌139株，其中G-杆菌78株（占56．1％），G＋球菌31株（22．3％），真菌30株（21．6％）。G＋杆菌以铜绿假单胞菌为主，占34．6％，其次为肺炎克雷伯菌（19．2％）；G＋球菌以金黄色葡萄球菌为主，占58．1％；真菌以白色念珠菌为主，占76．7％；且多种抗生素耐药，G＋球菌对万古霉素敏感。结论G＋杆菌是ICU老年院内下呼吸道感染主要的病原菌，铜绿假单胞菌、肺炎克雷伯菌、金黄色葡萄球菌和白色念珠菌是针对性治疗的重要致病菌。
Objective To study the distribution characteristics and drug resistance of pathogens in elderly patients with nosocomial lower respiratory tract infection in ICU. Methods 67 eases of the distribution characteristics and drug resistance of pathogens were analyzed retrospectively in elderly patients with nosocomial lower respiratory tract infection in ICU. Results A total of 67 pathogens were identified liq specimens from the lower respiratory tract secretion. The rate of gram-negative baete.ria,gram-positive bacteria and fungi were 56.1% ,22.3% and 21.6% respectively. The most common pathogens of gram-negative bacteria were Pseudomonas aeruginosa（34.6% ）, that was followed by Klebsiella pneumoniae（ 19.2% ）. The most common pathogens of gram-positive bacteria were Staphylococ- cus aureus（58.1% ）. The most common pathogens of fungi were Candida albieans（76.7% ）. They were resistant to multiple antibiotics,the pathogens of gram-positive were sensitive to Vaneo. Conclusion The most common pathogens in elderly patients with nosocomial lower respiratory tract infection in ICU are gram-positive bacteria. Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus and Candida albieans are important pathogen of targeted therapies.
