目的：为了及时动态掌握烧伤病人感染菌生态学及药敏情况。方法：收集我科1994年～1997年烧伤创面分泌物，各种导管插管，血液标本226份进行细菌学调查。结果：细菌培养阳性138份（58．8％），其中创面分泌物送检160份，阳性120份（75％），导管插管标本40份，阳性10份（25％），血液标本26份，阳性8份（30．8％）；共检出细菌14种153株，耐甲氧西林金葡菌高居第一位，占23．5％，绿脓杆菌次之，占17．6％。药敏结果提示：耐甲氧西林金葡菌对去甲万古霉素最敏感（100％），其次为环丙沙星（87．7％），其它均耐药；革兰氏阴性杆菌对舒普深、复达欣耐药率最低。结论：耐甲氧西林金葡菌已取代绿脓杆菌上升为第一位优势菌，且只对去甲万古霉素，环丙沙星敏感。
Objective: To timely and dynamically learn the ecology and drug sensitivity of infected patients. Methods: Bacteriological investigations were conducted on 226 specimens from the burn wounds of our department from 1994 to 1997, including catheter intubation and blood samples. Results: 138 (58.8%) samples were positive for bacterial culture, of which 160 were for examination of wound secretions, 120 were positive (75%), 40 were catheter cannulae, 10 were positive (25%), and 26 were blood specimens. 8 (30.8%) were positive. A total of 14 strains of 153 strains were detected. The methicillin-resistant Staphylococcus aureus ranked first, accounting for 23.5%, and Pseudomonas aeruginosa followed, accounting for 17.6%. Drug susceptibility results suggest that methicillin-resistant Staphylococcus aureus is the most sensitive to norvancomycin (100%), followed by ciprofloxacin (87.7%), all other resistance; Gram-negative bacilli to Shu Pu deep, complex Daxin has the lowest resistance rate. CONCLUSIONS: methicillin-resistant S. aureus has replaced P. aeruginosa as the dominant bacterium, and it is only sensitive to norvancomycin and ciprofloxacin.
