目的通过对我院ICU医护人员、清洁工的手及鼻前庭耐甲氧西林金黄色葡萄球菌(MRSA))带菌状况研究,及时发现携带者,探讨带菌与发生感染之间的关系,阻断交叉感染途径。方法按常规方法,对我院ICU工作人员的手及鼻前庭进行随机采样培养,手标本培养方法按《全国临床检验操作规程》微生物部分进行培养鉴定,鼻前庭标本培养是通过FOX(头孢西丁KB法药敏试验)鉴定。结果鼻前庭取标本90份,查出金黄色葡萄球菌携带者28人,其中25人MRSA为阴性,占总检查27.8%,2人MRSA阳性,占总检查2.2%。手培养取标本130份,查出金黄色葡萄球菌携带者10人,占总检查7.6%,其中MRSA病原菌携带者为2人,占总检查1.5%。8例查出克雷伯菌,占总检查6.1%。结论医护人员手及鼻咽部均存在着MRSA带菌,应提高医护人员对MRSA感染的认识度,采取严密的消毒隔离措施以降低我科MRSA感染率,防止交叉感染的发生。
OBJECTIVE To study the carrier status of ICU medical staff, cleaner hand and nasal vestibule methicillin-resistant Staphylococcus aureus (MRSA) in our hospital and find out the carriers in time to explore the relationship between carrier infection and infection, Way of infection. Methods According to the routine method, the hand and nasal vestibule of ICU staff in our hospital were randomly sampled and cultured. The cultivation method of hand specimens was identified and identified according to the microorganism part of “National Clinical Laboratory Procedures”. The culture of nasal vestibular specimens was performed by FOX KB method drug sensitivity test) identification. Results A total of 90 specimens of nasal vestibule were collected. Staphylococcus aureus was detected in 28 of them. 25 of them were negative for MRSA, accounting for 27.8% of the total, 2 were positive for MRSA, accounting for 2.2% of the total. 130 samples were taken from the hand culture, and 10 persons were detected for Staphylococcus aureus, accounting for 7.6% of the total. Among them, 2 were carriers of MRSA pathogens, accounting for 1.5% of the total. 8 cases detected Klebsiella, 6.1% of the total examination. Conclusion The MRSA was found in the hands and nasopharynx of the medical staff. The medical staff should be more aware of the MRSA infection and adopt strict disinfection and isolation measures to reduce the infection rate of MRSA in our department and prevent the cross-infection.
