摘要: 目的:对2015—2019年大理大学第一附属医院临床样本中分离出的铜绿假单胞菌(Pseudomonas aeruginosa,PAE)耐药性
进行动态分析,为临床医师合理选择抗菌药物提供参考。方法:对2015—2019年临床送检样本进行常规分离培养、菌株鉴定及药
敏试验,应用WHONET 5.6和SPSS 20.0软件对数据进行统计分析。结果:2015—2019年,共分离出609株PAE非重复菌株,且呈
逐年上升趋势。其中5年间检出率最高的标本来源均为痰液,其次为分泌物和肺泡灌洗液。分离出的PAE主要分布于呼吸内
科、ICU和儿科。药敏试验结果显示:该院PAE对亚胺培南、头孢他啶、头孢哌酮/舒巴坦、庆大霉素以及头孢吡肟整体耐药率5年
间有趋势变化,年间耐药率差异有统计学意义(P <0.05)。对呋喃妥因、复方磺胺甲噁唑的耐药率5年间无明显变化,阿米卡星耐
药率5年间波动变化。结论:5年间PAE对抗菌药物的耐药趋势稳定,应加强细菌耐药性动态监测,指导临床合理使用抗菌药物。

Abstract: Objective: To dynamically analyze the distribution and drug resistance of Pseudomonas aeruginosa isolated from clinical
samples of the First Affiliated Hospital of Dali University from 2015 to 2019, and to provide reference in rational antibiotics use for
clinicians. Methods: Routine isolation and culture, strain identification and drug sensitivity test were carried out on the clinical
samples collected during 2015 to 2019. The data were analyzed with WHONET 5.6 and SPSS 20.0 software. Results: A total of 609
PAE non-repetitive strains were isolated in the hospital from 2015 to 2019, and the numbers of PAE strains isolated increased year by
year. Among them, the samples with the highest detection rate were sputum, followed by secretions and alveolar lavage fluid.
Meanwhile, the top three departments of isolated PAE were Respiratory Medicine, ICU and Pediatrics. The results of the drug
susceptibility test showed that the overall resistance rate of PAE to imipenem, ceftazidime, cefoperazone/sulbactam, gentamicin and
cefepime showed a trend change during 5 years, and the difference in resistance rate between the years was statistically significant(P <
0.05). Its resistance rate to nitrofurantoin and compound sulfamethoxazole did not change significantly, but the resistance rate to
amikacin fluctuated in the 5 years. Conclusion: The trend of antibiotics resistance of PAE was stable in the past 5 years. The dynamic
monitoring of bacterial drug resistance should be strengthened to guide the rational use of antibiotics in clinic.

Key words: Pseudomonas aeruginosa, drug resistance, antibiotics, dynamic monitoring
