目的 :了解医务人员鼻咽部的带菌状况。方法 :采用常规分离培养法对 178例医务人员的鼻咽拭子标本进行分离培养 ,药敏试验根据 1999年美国 NCCL S有关抗生素敏感试验标准进行 ,流感嗜血杆菌β-内酰胺酶检测采用 Nitrocefin纸片法 ,耐青霉素肺炎链球菌 (PRP)检测采用 E- test法。结果 :2 5 .8%的医务人员鼻咽部携带流感嗜血杆菌 ,其产 β-内酰胺酶率 4.3% ;5 2 .8%携带副流感嗜血杆菌 ;11.8%携带金黄色葡萄球菌 ,其中耐苯唑西林的为 31.1% ;9.6 %携带肺炎链球菌 ,其中 PRP为 2 9.4%。结论 :医务人员的鼻咽部普遍携带病原菌 ,且普遍耐药 ,是医院内感染的主要传染源 ,因此采取相应措施 (如医务人员与病人接触时戴口罩 ) ,这对防止医院内感染具有重要的作用。
Objective : To understand the status of carriers in the nasopharynx of medical personnel. METHODS: Nasopharyngeal swab specimens of 178 medical personnel were isolated and cultured by routine isolation and culture. The drug susceptibility test was carried out according to the 1999 NCCL S standards on antibiotic susceptibility testing, and the Haemophilus influenzae β-lactamase assay was performed on Nitrocefin. Paper method, penicillin-resistant pneumococci (PRP) test using E-test method. Results: 25.8% of medical personnel carried Haemophilus influenzae in the nasopharynx, and their rate of producing beta-lactamase was 4.3%; 52.8% of them carried Haemophilus parainfluenzae; 11.8% carried Staphylococcus aureus, Of these, 31.1% were resistant to oxacillin; 9.6% contained S. pneumoniae, of which PRP was 2.4%. Conclusion: The nasopharyngeal part of the medical staff carries pathogenic bacteria and is generally drug resistant. It is the main source of infection in hospitals. Therefore, corresponding measures (such as wearing masks when medical personnel contact the patient) are important to prevent infections in hospitals. The role.
