摘要
目的研究医院内各种细菌存在情况,分析其与医院感染发生的联系,为控制医院感染提供依据。方法在动态环境下,按照国家医院感染有关规范进行取材、培养、分离、鉴定。结果医务人员双手、门把手、空气、患者用具、治疗台面(配液台)5个项目污染较为严重,检出率分别为:58.0%、56.7%、56.0%、43.3%、36.7%,被检出的细菌中以非发酵菌为主,占50.0%;肠杆菌属次之,占28.6%;革兰阳性球菌占21.4%。结论必须对医院环境进行日常动态监测,对控制医院感染有重要作用,同时由于医院内环境的变化,大量抗菌药物的使用和滥用,导致医院内细菌谱也发生了变化,非发酵菌已成为院内环境中主要细菌,革兰阳性球菌也有增加的趋势,应引起高度重视。
OBJECTIVE To observe the presence of various bacteria in hospitals and to analyze the relationship between bacteria and hospital-acquired infections, in order to provide the basis for control of hospital-acquired infections. METHODS Under dynamic environment, bacteria have been sampled, cultured, isolated, and identified in accordance with the relevant national norms about the nosocomial infection. RESULTS The pollution was more serious on the treatment tables, medical personnel hands, door handles, air, and patients＇ appliances. The detection rates were as follows： 58. 0% of hand, 56. 7% of door handles, 56. 0% of air, 43. 3% of patients＇ appliances, and 36.7% of treatment tables. The detected bacteria mainly were non-fermenting bacteria （50.0%）, followed by Enterobacter, （28. 6%） and Gram-positive cocci （21. 4%）. CONCLUSIONS The pollution is more serious on the treatment tables, medical personnel hands, door handles, air, and patients＇ appliances under a hospital environment. It is necessary to overcom the weak links in the daily dynamic monitoring and at the same time to carry out the routine monitoring,, which has an important role in control of nosocomial infection. The spectrum of bacteria in hospitals has changed due to the changing hospital environment and useing and misuseing a large number of antibiotics. It should pay much attention to non-fermenting bacteria, the main bacteria in hospital environment, and the Gram-positive cocci are also in an increasing trend.
