目的了解医护人员鼻前庭带菌状况,为预防和控制医院感染提供参考。方法通过现场采样和实验室检测方法,对天津市医疗机构部分医务人员鼻前庭带菌情况进行检测分析。结果共抽检180名医护人员,鼻前庭带菌数超标率为70%,其中市区医疗机构超标率为60%,郊县医疗机构超标率为80%,两者之间差异有显著统计学意义。居前3位的是产气肠杆菌、肺炎克雷伯菌和变形杆菌。结论天津市医护人员鼻前庭带菌率较高,居前3位的细菌均为严重医院感染病原菌,应采取适当防控措施以降低鼻前庭带菌率。
Objective To understand the status of nasal vestibular carriers in health care workers and provide references for the prevention and control of nosocomial infections. Methods By means of field sampling and laboratory testing methods, the nasal vestibular bacteria in some medical staffs in Tianjin medical institutions were detected and analyzed. Results A total of 180 medical staff were sampled. The rate of over-standard bacteria in the frontal vestibule was 70%. The over-standard rate of medical institutions in urban areas was 60% and the over-standard rate of medical institutions in suburban counties was 80%. The difference was statistically significant. The top three are Enterobacter aerogenes, Klebsiella pneumoniae and Proteus. CONCLUSIONS: The prevalence rates of nasal vestibular in medical staff in Tianjin are relatively high. The top three bacteria are serious pathogens causing nosocomial infection. Appropriate prevention and control measures should be taken to reduce the incidence of nasal vestibular.
