手术室护士鼻、咽部机会致病菌携带状况与干预

The colonization and intervention of opportunistic pathogens on nasal vestibule and pharyngeal portion among nurses in operating room

目的了解手术室护士鼻、咽部带菌情况，以加强对手术室护士医院感染的预防与控制。方法采用常规方法对在手术室工作的30名护士分别进行鼻前庭或咽拭子培养和菌种鉴定及抗生素敏感度检测。结果从15份咽拭子中分离到肺炎克雷伯菌1株，对氨苄青霉素和氧哌嗪青霉素耐药。15份鼻前庭拭子中分离到表皮葡萄球菌9株，对多种抗生素耐药，金黄色葡萄球菌1株，对红霉素耐药。结论手术室护士鼻前庭机会致病菌携带率较高，表皮葡萄球菌对抗生素耐药率高，应建立手术室医务人员医院感染监测和预警制度。

Objective To investigate the colonization of the nasal and pharyngeal portion among nurses in operating room for the prvention from hospital infection. Methods Nasal and throat swabs from 30 nurses were cultured and isolated, the tests of antibiotic susceptibility were performed as well. Results One species of Klebsiella pneumoniae from 15 throat swabs was isolated and the intibiotie suscepti- bility was reslstan to amlnobenzylpenieillln and piperacillin. 9 species of Staphylococcus epidermidis were isolated from 15 Nasal Vestibule swabs and were multi - antibiotic resistant. 1 species of Staphyloceus aureus was iasolated and was erytbromyeinresistant. Conclusions The rates of opportunistic pathogens from nurses in operating room are high and antibiotic resistand are high for Staphylococcus epidermidis. The surveillance of hospieal infection and early warning should pay more attantion.
