摘要
目的探讨腹部手术切口感染病原菌的分布及耐药性。方法采集伤口分泌物进行细菌培养,分离病原菌并进行鉴定;用琼脂扩散法(K-B法)做药物敏感试验,对病原菌耐药率进行分析。结果病原菌以革兰阴性杆菌为主,占76.9%;其中分离率最高的为大肠埃希菌(24.9%)、铜绿假单胞菌(17.6%)、肺炎克雷伯菌(17.2%),耐甲氧西林金黄色葡萄球菌(MRSA)检出率为40.0%;产超广谱β-内酰胺酶(ESBLs)大肠埃希菌和肺炎克雷伯菌检出率为45.2%;以上病原菌均检测出较高的耐药率。结论必须采取切实的防治对策,预防与控制腹部手术切口感染。
OBJECTIVE To study the distribution and resistance of pathogens from infected surgical incision. METHODS The secretion from infected wounds was cultured in order to identify pathogens by routine methods. Resistance ratio to antibiotics was determined by disk diffusion method. RESULTS Most of the pathogens were Gram-negative bacilli accounting for 76. 9%, among which the isolation rates of Escherichia coli （24. 9%）, Pseudomonas aeruginosa （17.6%） and Klebsiella pneumoniae （17.2%） were the highest. The isolation rates of meticillin-resistant Staphylococcus aureus （MRSA） were 40.0% （14/35） and that of ESBLs producing E. coli and K. pneumoniae were all 45. 2% （42/93）, which were highly resistant to antibiotics. CONCLUSIONS Preventive measures should be taken to prevent and control surgical incision infection.
