儿科医务人员鼻前庭耐甲氧西林金黄色葡萄球菌携菌情况调查

Situation of Methicillin-Resistant Staphylococcus Aureus Carrying among Nasal Vestibule of Medical Personnels in Pediactrics

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 study the situation of bacteria carrying in nasal vestibule of medical personnels in intensive care unit（NICU,PICU,CCU）,so as to strengthen prevention and control of nosocomial infection in intensive care unit. Methods： The conventional method of swabbing the nasal vestibule to culture strain identification was carried in medical personnels in NICU,PICU,CCU and orthopedics department（one）. Results： Two hundreds and forty one specimens of the nasal vestibule of medical personnels were collected,there were 151 specimens in the NICU,30 specimens in the PICU,28 specimens in the CCU,32 specimens in the orthopedics department（one）. A total of 55 strains of Staphylococcus aureus were detected,and the detection rate was 22. 8%,eight strains of methicillin-resistant Staphylococcus aureus（MRSA） were detected,the detection rate was 3. 3%,and 41 strains of methicillinresistant coagulase negative Staphylococci（MRCNS） were found,the detection rate was 17. 0%. The carrying rate of Staphylococcus aureus（3. 8%） and MRCNS（19. 6%） in nasal vestibule of the medical personnels in ICU were higher than those in the orthopedics department（one）（P〈0. 05）. Conclusion： The situation of nasal vestibular bacteria carrying in medical personnels is not optimistic,opportunistic pathogen carrying rate is high,the medical personnels of different departments with nasal vestibular bacteria carrying hare obvious differences,eliminate bacteria colonization can reduce the risk of cross infection in hospital infection.
