目的:了解重症监护病房(NICU、PICU、CCU)医务人员鼻前庭携菌状况,以加强重症监护病房医院感染的预防与控制。方法:对NICU、PICU及CCU医务人员和骨一科医务人员的鼻前庭拭子进行培养和菌种鉴定。结果:共采集医务人员鼻前庭标本241份,其中NICU 151份,PICU 30份,CCU 28份,骨一科32份。241份标本检出55株金黄色葡萄球菌,检出率22.8%;检出8株耐甲氧西林金黄色葡萄球菌(MRSA),检出率为3.3%;检出41株凝固酶阴性葡萄球菌(MRCNS),检出率17.0%。重症监护病房医务人员鼻前庭MRSA携带率(3.8%)、MRCNS携带率(19.6%)均高于普通科室骨一科(P<0.05)。结论:医务人员鼻前庭携菌情况严峻,条件致病菌携带率较高,不同科室医务人员鼻前庭携菌情况有明显差异,对存在MRSA定植的医护人员尽快采取消除定植的措施可降低医院交叉感染的风险。
Objective: To understand the status of nasal vestibule carried by medical staff in intensive care unit (NICU, PICU, CCU) to enhance the prevention and control of nosocomial infection in intensive care unit. Methods: The nasal vestibular swabs from NICU, PICU, CCU medical staff and orthopedic medical staff were cultured and identified. Results: A total of 241 nasal vestibular specimens were collected from medical staff, including 151 NICU, 30 PICU, 28 CCU and 32 bone-first subjects. 55 strains of Staphylococcus aureus were detected in 241 samples, with a detection rate of 22.8%. Eight strains of MRSA were detected, the detection rate was 3.3%. 41 strains of coagulase-negative staphylococci (MRCNS), the detection rate was 17.0%. MRSA carrier rate (3.8%) and MRCNS carrier rate (19.6%) were higher in the ICU than those in the common department (P <0.05). CONCLUSIONS: In medical staff, the situation of harboring bacteria in the nasal vestibule is severe and the carrying rate of opportunistic pathogens is high. There are significant differences in carrying bacteria among the nasal vestiges of medical staff in different departments. As soon as possible, medical staffs with MRSA colonization can take measures to eliminate colonization and reduce hospital crossings The risk of infection.
