目的:了解我院急诊科的病原菌分布和耐药性。方法:回顾性分析我科2008-2015年病原菌的菌群分布和药敏结果。结果:共7 698株病原菌,前5位的病原菌依次是鲍曼不动杆菌、大肠埃希菌、绿脓杆菌、肺炎克雷伯杆菌、金黄色葡萄球菌。泛耐药鲍曼不动杆菌是急诊科最常见的耐药菌,对多种抗菌药物高度耐药。肺炎克雷伯菌对碳青霉烯类药物耐药率逐年升高。未发现对万古霉素和利奈唑胺耐药的金黄色葡萄球菌。结论:急诊科的病原菌以鲍曼不动杆菌、大肠埃希茵、金黄色葡萄球菌多见。病原菌的对常见抗茵药物的耐药率各有不同,应及时监测病原菌耐药性的变化,合理使用抗茵药物,减少耐药菌株的产生。
Objectives: To understand the distribution and drug resistance of pathogens in emergency department of our hospital. Methods: The bacterial distribution and drug susceptibility of pathogenic bacteria in our department from 2008 to 2015 were retrospectively analyzed. Results: A total of 7 698 pathogens, the top five pathogenic bacteria followed by Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus. Pan-resistant Acinetobacter baumannii is the most common emergency department of resistant bacteria, highly resistant to a variety of antimicrobial agents. Klebsiella pneumoniae carbapenem drug resistance rate increased year by year. No vancomycin and linezolid resistant S. aureus was found. Conclusion: The pathogen of emergency department is Acinetobacter baumannii, Escherichia coli and Staphylococcus aureus. Pathogens resistance rates of common anti-inflammatory drugs are different, should be promptly monitored changes in pathogens resistance, rational use of anti-inflammatory drugs, reduce the generation of drug-resistant strains.
