摘要
目的探讨外科手术后患者感染的病原菌分布及其耐药性。方法对2006年1-12月外科手术后感染送检标本进行培养分离的195株致病菌,采用WalkAway-40全自动细菌鉴定及药敏测试仪及NC31鉴定板进行了分析。结果在培养出的195株病原菌中,革兰阴性杆菌占74.4%,革兰阳性球菌25.6%,常见病原菌主要为大肠埃希菌(44株)、肺炎克雷伯菌(36株)、铜绿假单胞菌(33株)和金黄色葡萄球菌(20株);万古霉素和亚胺培南具有较好抗菌效果。结论密切监测外科感染病原菌,对预防治疗外科感染、合理应用抗菌药物有重要意义。
OBJECTIVE To investigate the distribution of nosocomial infection （NI） in patients after surgical procedures and antimicrobial resistant change of pathogens. METHODS A total of 195 strains of pathogenic bacteria isolated from the samples after surgical procedures from Jan 2006 to Dec 2006 were analyzed by WalkAway-40 system with NC31 system. RESULTS Among the 195 strains of pathogenic bacteria, there were Gram-negative bacilli（74.4 %） and Gram-positive cocci （25.6 %）. The dominating microorganisms were Escherichia coli, Klebsiella pneurnoniae, Pseudornonas aeruginosa and Staphylococcus aureus. The result showed that vancomycin and imipenem still had better activities to the bacteria. CONCLUSIONS Surgical incision infection should be monitored by some effective measures, and it is very important to prevent surgical infection and use antibiotics reasonably.
