    摘要:

    目的了解外科感染患者分离病原菌及耐药情况。方法采用回顾性调查的方法,对2013年1月—2014年1月某院外科患者送检标本分离的1 208株病原菌及其耐药性进行统计分析。结果1 208株病原菌中,革兰阴性(G-)菌780株(64.57%),革兰阳性(G+)菌301株(24.92%),真菌127株(10.51%)。主要标本来源为痰液(44.78%)、尿液(21.11%)、血液(11.51%)、脓液分泌物(10.26%)等。药敏结果示,大肠埃希菌和肺炎克雷伯菌产超广谱β内酰胺酶检出率分别为62.60%和33.61%,二者对亚胺培南耐药率为0.76%和15.57%。铜绿假单胞菌和鲍曼不动杆菌对亚胺培南耐药率达38.93%和75.80%。耐甲氧西林金黄色葡萄球菌和耐甲氧西林凝固酶阴性葡萄球菌检出率分别为71.68%和87.93%。结论该院外科感染分离的病原菌以G-菌为主,主要感染部位为呼吸道和泌尿道;多重耐药严重,尤其是碳青霉烯类耐药株,值得重视。

    Abstract:

    ObjectiveTo investigate the distribution and antimicrobial resistance of pathogens isolated from surgical patients with infection. MethodsDistribution and antimicrobial resistance of 1 208 pathogens isolated from surgical patients with infection from January 2013 to January 2014 were analyzed retrospectively. ResultsOf 1 208 pathogenic isolates, gramnegative bacteria, grampositive bacteria and fungi accounted for 64.57%(n=780),24.92%(n=301) and 10.51%(n=127) respectively. The main specimens were sputum (44.78%), urine (21.11%),blood(11. 51%), and pus(10.26%).Antimicrobial suscept ibility testing results showed that the producing rate of extendedspectrum βlactamases (ESBLs)  of Escherichia coli and Klebsiella pneumoniae was 62.60% and 33.61% respectively, resistant rate to imipenem was 0.76% and 15.57%, respectively. The resistant rate of Pseudomonas aeruginosa and Acinetobacter baumannii to imipenem was 38.93% and 75.80% respectively. Methicillinresistant Staphylococcus aureus and methicillinresistant coagulase negative Staphylococcus was 71.68% and 87.93% respectively. ConclusionThe major pathogens isolated from surgical patients with infection are gramnegative bacteria, the main infection sites are respiratory tract and urinary tract in this hospital; multidrug resistance is serious, especially carbapenem resistance, which should be paid attention.
