天津市299名医护人员手部带菌及其耐药分析

Bacteria Contamination on Hands of Medical Staff in Tianjin and Their Antibiotic Resistance

目的了解天津市医护人员手部带菌及其耐药情况。方法在医护人员消毒洗手前,以灭菌棉拭子涂抹双侧全手掌采样,增菌培养并对分离到的病原菌或条件致病菌做药物敏感性试验。结果在299份手拭子样本中共有50份带菌,带菌率为16.72%,分离到病原菌或条件致病菌菌株64株,以鲍氏不动杆菌、金黄色葡萄球菌和鲁氏不动杆菌为主要菌种,其中对≥3种抗菌药物耐药的有26株,占全部菌株的40.63%,检出耐甲氧西林葡萄球菌4株。结论医疗机构医护人员手部带有病原菌与条件致病菌,部分细菌耐药较严重,应引起重视,加强手卫生宣传与管理。

OBJECTIVE To investigate and analyze hand carrier state of medical staff in Tianjin and the antibiotic resistance of the pathogens. METHODS Bacteria or pathogens were isolated from the samples using a sterilized cotton swab on the whole hand before hand washing or hand disinfection, and drug sensitivity test was performed. RESULTS In 16.72% of all samples （50/299）, there were 64 kinds of bacteria or pathogens isolated. A. baumannil, Staphylococcus aureus and A. lwoffii were the most common bacteria, 40.6 % resistant to more then 3 kinds of drugs. Four Meticillin-resistant S. aureus （MRSA） strains were detected out. CONCLUSIONS The high rate of hand carrying bacteria and resistance in Tianjin should pay attention to.
