目的比较医务人员采用不同方法洗手的效果,对不同洗手方法进行评价。方法将内科、外科、儿科和五官科四个科室的48名医护人员随机分成4组,每组12人,分别采用氯己定醇皮肤消毒液、含氯消毒液、碘伏和皂液流水方式洗手,比较清洗效果并对培养出的菌株进行鉴定。结果采用四种不同方法洗手后,皮肤消毒液洗手合格率最高,病原菌分离率最低,没有检出金黄色葡萄球菌和大肠杆菌;皂液流水洗手合格率最低,病原菌分离率最高,检出金黄色葡萄球菌和大肠杆菌的株数最多;含氯消毒液和碘伏洗手效果次于皮肤消毒液洗手,而优于皂液流水洗手。结论采用不同方式洗手,消毒效果不同,皮肤消毒液洗手是最好的洗手方法,对控制医院感染具有较高的临床价值,值得推广。
Objective To compare the effects of medical staff using different methods of handwashing and to evaluate different handwashing methods. Methods Forty-eight medical staffs in four departments of internal medicine, surgery, pediatrics and ENT were randomly divided into 4 groups (12 in each group). They were treated with chlorhexidine alcohol skin disinfectant, chlorine disinfectant, iodophor and soap liquid respectively Wash hands, compare cleaning results, and identify cultivated strains. Results After washing with four different methods, the rate of hand-washing of skin disinfectant was the highest, while the rate of pathogen was the lowest. Staphylococcus aureus and Escherichia coli were not detected; the pass rate of washing soapy water was the lowest and the rate of pathogen was the highest Staphylococcus aureus and Escherichia coli strains were the most. Chlorine disinfectant and iodophor handwash were inferior to skin disinfectant, which was better than soap liquid. Conclusion Different handwashing and disinfecting effects are the best ways to wash hands with skin disinfectant. It is worthwhile to promote the control of nosocomial infections.
