烧伤患者创面与环境中病原微生物耐药性及相关性的研究

Drug Resistance of Pathogenic Microorganism from Surface of Burn Patients As Well As the Environment and Their Interrelation

了解烧伤科病人创面感染、环境监测的主要致病菌及其耐药性,探讨二者的关系。运用Sceptor鉴定仪对检出菌进行鉴定,K-B法对主要致病菌进行药敏试验。结果表明,引起烧伤创面感染的主要致病菌为不动杆菌(24.6%)、MRSA(19.8%)、绿脓杆菌(16.7%),烧伤科病房环境分离出的主要细菌为不动杆菌(17.7%)、绿脓杆菌(17.7%)、MRSA(13.3%),创面分离的致病菌与环境检出的细菌具有一定的相关性。特别是MRSA、MRSE,从创面与环境二者分离出的菌株具有相似的抗菌谱,这说明环境因素特别是医陪护人员的手表、物表成为该菌在烧伤病房传播的重要环节。

In order to understand pathogens of infected surface of burn patient as well as the environment and their drug-resistance, and to explore their interrelation, Sceptor was used to identify the detected pathogens and K-B method to detect drug sensitivity of main pathogens. The main pathogens of infected surface were Acinetobacter （24.6%）, MRSA （19.8%）, and Pseudornonas aeruginosa （16.7%）, whereas the main pathogens from burn wards were Acinetobacter （ 17.7 % ）, Pseudornonas aeroginosa （ 17.7 % ）, and MRSA （ 13.3 % ）. It may be elucidated that they have some interrelation. Pathogens isolated from the burn surface and the environment had similar antibiotic spectrum, especially in MRSA and MRSE. These results demonstrated that the important factor of bacteria spreading in the burn ward is the environment factor, especially the surface of objects the hands of doctor and nurses.
