目的了解烧伤科工作人员鼻咽部病原菌带菌状况,并探讨对烧伤患者院内感染的影响。方法于2006年10～12月、2007年7月至2008年1月和2008年7～9月,每月对烧伤科某病区工作人员进行鼻前庭细菌采样,采样后标本细菌培养、菌株分离及菌种鉴定。结果长期在烧伤科工作的工作人员鼻前庭机会致病菌的携带率在54.18%,表皮葡萄球菌检出率最高,为24.67%;其次是金黄色葡萄球菌,为20.70%,其中耐甲氧西林金黄色葡萄球菌(MRSA)分离出2株,占总株数的0.88%,肺炎克雷伯杆菌和产气肠杆菌分别为4.85%和3.96%;金黄色葡萄球菌、肺炎克雷伯杆菌,产气肠杆菌的检出在前后3次调查中,大多数是在相同的人员身上发现的。结论长期在烧伤科工作的工作人员鼻前庭机会致病菌的携带率较高,金黄色葡萄球菌、肺炎克雷伯杆菌,产气肠杆菌在一些工作人员的鼻前庭已经长期定植,在医疗活动中,工作人员可能会将鼻前庭定植的细菌传播给住院患者,成为烧伤科患者发生院内感染的原因之一。
Objective To understand the infection status of nasopharyngeal pathogenic bacteria in burn department staff and to explore the influence on nosocomial infection in burn patients. Methods From October to December 2006, from July 2007 to January 2008 and from July to September 2008, samples of nasal vestibular bacteria were collected monthly from staff in a ward of a burn department. Bacterial culture and strain separation were performed after sampling And species identification. Results The results showed that the prevalence of opportunistic pathogens in nasal vestibular processes was 54.18% in long-term work in burn department, the highest detection rate was Staphylococcus epidermidis (24.67%), followed by Staphylococcus aureus (20.70%), of which methicillin-resistant Staphylococcus aureus (MRSA) isolated two strains, accounting for 0.88% of the total number of strains, Klebsiella pneumoniae and Enterobacter aerogenes were 4.85% and 3.96%; Staphylococcus aureus, Klebsiella pneumoniae, gas Enterobacteriaceae detected in the first three surveys, most of them were found in the same personnel. Conclusion Long-term burdens of staff working in burns department have a higher carrying rate of opportunistic pathogenic bacteria in nasal vestibule. Staphylococcus aureus, Klebsiella pneumoniae and Enterobacter aerogenes have been colonized long-term in the nasal vestibule of some staff members. During medical activities , Staff may spread nasal vestibular bacteria to hospitalized patients and become one of the causes of nosocomial infections in burn patients.
