老年患者呼吸机相关性肺炎的病原学以及耐药性分析

目的:分析老年患者呼吸机相关性肺炎的病原学以及耐药性。方法:回顾性分析本院在2010年2月-2012年12月治疗的58例老年呼吸机相关性肺炎患者的临床资料。结果:共检出病原菌196株,其中革兰阴性菌占86.73%,革兰阳性菌占13.27%,革兰阴性菌铜绿假单胞菌占23.47%,鲍氏不动杆菌占16.84%,革兰阳性菌金黄色葡萄球菌占14.29%;病原菌对常用抗生素的耐药性较高。结论:革兰阴性菌是老年患者呼吸机相关性肺炎的主要致病菌,治疗时应合理使用抗菌药物。

Analysis on Pathogen Distribution and Pathogen Drug Resistance in Elder Patients with Ventilator Associated Pneumonia

Objective：To analyze the pathogen distribution and pathogen drug resistance in elder patients with ventilator associated pneumonia. Method：Retrospective analyzed the clinical data of the 58 elder patients with ventilator associated pneumonia in our hospital from February 2010 to December 2012.Result：196 pathogens were isolated from the 58 elder patients with ventilator associated pneumonia,of which gram-negative bacterium accounted for 86.73%,gram positive bacteria accounted for 13.27%.The pseudomonas aeruginosa was 23.47%,acinetobacter baumannii was 16.84%and staphylococcus aureus was 14.29%.The antibiotic resistance of the pathogens were increasingly higher.Conclusion：The main pathogens of VAP elder patients with ventilator associated pneumonia is gram-negative bacterium.Treatment should be rational use of antimicrobial agents.
