摘要
目的调查急诊重症监护病房中鲍氏不动杆菌流行情况及传播规律。方法采集患者体表、病房环境、医护人员标本分离鲍氏不动杆菌进行分析,用琼脂稀释法检测MIC值。结果50.0%的患者在入院后出现鲍氏不动杆菌的体表定植;入院>7 d的患者80.0%出现体表定植;体表有定植的患者73.7%痰培养出鲍氏不动杆菌;体表定植菌与呼吸道分离菌100.0%为泛耐药株;环境及医护人员手中分离到鲍氏不动杆菌>20.0%。结论鲍氏不动杆菌在患者体表、病房环境及医护人员手中大量存在,应加强环境消毒和医护人员手卫生的监督管理以减少由泛耐药鲍氏不动杆菌引起的医源性感染。
OBJECTIVE To investigate the prevalence and transmission regularity of Acinetobacter baumannii in emergency ICU.METHODS A.baumannii strains were isolated from body surface of patients and medical personnel and their environment.The MIC of isolated strains were tested with agar dilution and analyzed by WHONET5.4.RESULTS 50% of the patients had body surface colonization of A.baumannii after admission to hospital.Among them,80% were colonized with in 7 days and 73.7% had A.baumannii from sputum culture.All of the strains isolated from body surface and respiratory tract were pan-resistant.Above 20% of A.baumannii were isolated from environment and medical personnel′s hands.CONCLUSIONS A.baumannii extensively exist on body surface of the patients,environment of words and medical personnel′s hands.It is necessary to enhance the disinfection of environment and supervisory management of hands hygien among the medical personnel.
