摘要: 目的:分析20182020年大理市某三级甲等医院肺炎克雷伯菌(KP)的临床分布及耐药趋势,以期为临床治疗提供实验依据。方法:对该院20182020年临床送检的标本进行分离培养、菌株鉴定及药敏试验,回顾性分析KP的临床分布及耐药趋势。结果:20182020年,共分离得到KP 1 642株,其中,产超广谱β-内酰胺酶(ESBL)KP(产ESBL-KP218株,耐碳青霉烯类KPCR-KP56株;KP和产ESBL-KP的主要科室来源为儿科,CR-KP的主要科室来源为重症监护室(ICU)。药敏结果显示:产ESBL-KP对β-内酰胺类抗菌药物有着极高的耐药性,但对碳青霉烯类药物尚未发现耐药情况;CR-KP对药敏试验中四分之三的抗菌药具有较高的耐药性。结论:面对KP耐药性日益增高的问题,临床各科室应提高警惕,及时送检患者标本,同时,医护人员要加强自我防护,防止患者之间交叉感染,合理使用抗生素。

Abstract: Objective To analyze the clinical distribution and drug resistance trend of Klebsiella pneumoniaKP in a tertiary hospital A in Dali from 2018 to 2020 in order to provide experimental evidence for clinical treatment. Methods The specimens submitted for clinical examination in this hospital from 2018 to 2020 were isolated and cultured strain identification and drug susceptibility test were conducted and the clinical distribution and drug resistance trend of KP were retrospectively analyzed. Results From 2018 to 2020 a total of 1 642 KP strains were isolated including 218 strains of ESBL- Klebsiella pneumoniae ESBL-KP and 56 strains of carbapenems-resistant KPCR-KP. The main department source of KP and ESBL-KP was pediatrics and the main department source of CR-KP was the intensive care unit ICU. The drug susceptibility results showed that ESBL-KP had extremely high resistance to β-lactam antibacterials but no resistance to carbapenems had been found. CR-KP was highly resistant to three-quarters of the antibacterial drugs in the susceptibility test. Conclusion Facing the problem of increasing resistance to KP clinical departments should be vigilant and send patient specimens for examination in time. At the same time medical staff should strengthen self-protection prevent cross-infection among patients and strengthen the rational use of antibiotics.
