口腔医疗机构医院感染及微生物污染现状调查

Medical infection in dental medical institutions and current survey on microbial contamination

目的:增强医务人员的自身防护意识,减少医源性感染的发生。方法:采口腔科医务人员血清150份,口腔医疗器械221份用ELISA方法进行HBV、HCV、HIV检测,44份口腔治疗椅系统水样品及221份口腔医疗器械进行菌落计数及部分样品的细菌分离鉴定。结果:150份血清样品HBV感染率为37.33%(56/150),HCV的感染率1.3%(2/150),HIV未检出。221份口腔医疗器械HBV感染率为1.36%(3/221),HCV、HIV未检出,微生物检出率为14.03%(31/221),44份口腔治疗椅系统水样品的细菌检出率为77.27%(34/44)。结论:口腔医疗机构微生物污染现象比较严重,应加强预防消毒管理。

Objective：To enhance the self-protection awareness in dental staff and reduce the morbidity due to occupational exposure.Methods：Get 150 serum in healthcare workers and 221 dental medical instrument,and detect hepatitis B,C and HIV with ELISA.Get 44 dental unit waterline and 221 dental medical instrument,and count bacteria colonies and classify after culture.Results：HBV infection rate is 37.33%（56/150）,HCV infection rate is 1.3%（2/150）,and HIV is not detected in 150 serum samples.HBV infection rate is 1.36%（3/221）,HCV and HIV are not detected in 221 dental medical instrument.Microbial detection rate is 14.03%（31/221）.Bacteria detection rate is 77.27%（34/44） in 44 dental waterline.Conclusion：Microbial contamination is serious in dental medical institution,and prevention and sterilization management should be strengthened.
