目的了解新生儿重症监护病房(NICU)环境表面耐甲氧西林葡萄球菌(MRS)污染状况,为加强NICU环境卫生管理提供依据。方法通过现场采样和细菌分离鉴定技术,对某医院NICU内高频接触的物体表面细菌污染进行检测。结果从该NICU内保温箱、床具、水龙头、卫生洁具等10余种物体表面共分离到MRS 54株,分离阳性率为24.7%,所分离的MRS菌株均携带mec A基因。NICU物体表面MRS污染率较高的依次为水龙头、推车拉手、电脑键盘、开关和病历夹。结论 NICU高频接触表面的耐甲氧西林葡萄球菌污染普遍,应加强病房内环境物体表面卫生管理,以降低物体表面MRS定植的机会。
Objective To understand the status of methicillin-resistant Staphylococcus aureus (MRS) on the surface of neonatal intensive care unit (NICU) and provide the basis for strengthening the environmental health management of NICU. Methods The bacterial contamination on the surface of high-frequency contact in a hospital NICU was detected by on-site sampling and bacterial isolation and identification. Results 54 strains of MRS were isolated from the surface of more than 10 kinds of incubators, bedding, faucets, sanitary ware, etc. in the NICU. The positive rate of isolation was 24.7%. The isolated MRS strains all carried the mec A gene. The highest MRS contamination rates on the surface of NICU objects were faucet, stroller handle, computer keyboard, switch and medical record holder. Conclusion The contamination of methicillin-resistant Staphylococcus aureus on the surface of NICU is common, and the surface health management of environmental objects in wards should be strengthened to reduce the chance of MRS colonization on the surface of objects.
