【摘要】：目的探讨重症监护病房(ICU)医务人员鼻腔带菌及其耐药情况,为制订医院感染防控措施提供依据。方法采用棉拭子采样法,对某院2014年4月—2015年3月ICU医务人员鼻腔黏膜进行采样,检测其携带病原菌及其耐药情况。结果共采集450份鼻腔标本,分离病原菌137株,检出率为30.44%。不同性别、年龄、工作岗位、工龄、文化程度的医务人员鼻腔带菌检出率比较,差异均无统计学意义(P0.05);医务人员不同季节鼻腔带菌检出率比较,差异具有统计学意义(P0.05)。其中革兰阴性菌82株(占59.85%),以肺炎克雷伯菌(21.16%)、产气肠杆菌(18.98%)为主;革兰阳性菌55株(占40.15%),以金黄色葡萄球菌(18.98%)、表皮葡萄球菌(15.33%)为主。检出38株(27.74%)多重耐药菌。耐甲氧西林金黄色葡萄球菌占7.69%(2/26),耐亚胺培南肺炎克雷伯菌占3.45%(1/29),耐亚胺培南产气肠杆菌占3.85%(1/26)。结论 ICU医务人员鼻腔病原菌携带率较高,多重耐药菌检出率高。
[Abstract]:Objective to investigate the nosanal bacteria and drug resistance of medical staff in ICU, and to provide evidence for the prevention and control of nosocomial infection. Methods a cotton swab sampling method was used to sample the nasal mucosa of medical staff in a hospital from April 2014 to March 2015, and the pathogens were detected and their drug resistance was detected. The results of 450 nasal cavity were collected. 137 strains of pathogenic bacteria were isolated, the detection rate was 30.44%. in different sex, age, work position, working age, and cultural degree of medical personnel in the detection rate of nasal cavity, the difference was not statistically significant (P0.05); the difference of detection rate of nasal cavity bacteria in medical personnel in different seasons was statistically significant (P0.05). Among them, 82 (59.8) were Gram-negative bacteria (59.8). 5%) Klebsiella pneumoniae (21.16%) and Enterobacteriaceae (18.98%), 55 strains of Gram-positive bacteria (40.15%), Staphylococcus aureus (18.98%) and Staphylococcus epidermidis (15.33%). 38 (27.74%) multi resistant bacteria were detected. Methicillin resistant Staphylococcus aureus was 7.69% (2/26), Klebsiella pneumoniae resistant to imipenem accounted for 3.45% (1/29), and resistant to imipenem pneumonia. Imipenem Enterobacter pneumoniae accounted for 3.85% (1/26). Conclusion ICU medical staff have a high rate of nasal pathogen carrying, and the detection rate of multi drug resistant bacteria is high.
