本研究的目的是确定微生物是否可以从临床医生和护士使用的听诊器的膜中分离出来，并分析不同的清洁方法是否可以减少细菌的定植程度。我们设计了一个横向的前后对照研究，其中检查了122个听诊器。凝固酶阴性葡萄球菌（也是潜在致病微生物）与其他13种潜在致病微生物分离，包括金黄色葡萄球菌、不动杆菌和团聚肠杆菌。最有效的防腐剂是丙醇。对急诊科（ED）工作人员清洁习惯的分析表明，45%的人每年或从不清洁听诊器。潜在病原微生物的分离表明，听诊器不仅在急诊科，而且在其他医院病房和门诊也必须被视为潜在的感染媒介。
The purposes of this study were to determine whether microorganisms can be isolated from the membranes of stethoscopes used by clinicians and nurses, and to analyse whether or not the degree of bacterial colonization could be reduced with different cleaning methods. We designed a transversal before-after study in which 122 stethoscopes were examined. Coagulase negative staphylococci (which are also potentially pathogenic microorganisms) were isolated together with 13 other potentially pathogenic microorganisms, including S. aureus, Acinetobacter sp. and Enterobacter agglomerans. The most effective antiseptic was propyl alcohol. Analysis of the cleaning habits of the Emergency Department (ED) staff, showed that 45 % cleaned the stethoscope annually or never. The isolation of potentially pathogenic microorganisms suggests that the stethoscope must be considered as a potential vector of infection not only in the ED but also in other hospital wards and out-patient clinics.
