OBJECTIVE
To determine whether a single-use stethoscope diaphragm barrier surface remains aseptic when placed on pathogen-contaminated stethoscopes.
METHODS
From May 31 to August 5, 2019, we tested 2 separate barriers using 3 different strains of 7 human pathogens, including extended-spectrum β-lactamase-producing methicillin-resistant and vancomycin resistant
RESULTS
For all diaphragms with either of the 2 barriers tested, no growth was recorded for any of the pathogens. Stethoscopes with aseptic barriers remained sterile for up to 24 hours. These single-use barriers also provided aseptic surfaces when stethoscope diaphragms were inoculated with human specimens, including saliva, stool, urine, and sputum.
CONCLUSION
Disposable aseptic diaphragm barriers may provide robust and efficient solutions to reduce transmission of pathogens via stethoscopes.
目的
确定一次性使用的听诊器膜片屏障表面放置在被病原体污染的听诊器上时是否保持无菌状态。
方法
2019年5月31日至8月5日，我们使用7种人类病原体的3种不同菌株测试了2种不同的屏障，包括产超广谱β-内酰胺酶的耐甲氧西林和耐万古霉素菌株。
结果
对于测试的2种屏障中的任何一种的所有膜片，均未记录到任何病原体的生长。带有无菌屏障的听诊器在长达24小时内保持无菌。当听诊器膜片接种包括唾液、粪便、尿液和痰液在内的人体标本时，这些一次性屏障也提供了无菌表面。
结论
一次性无菌膜片屏障可能为减少病原体通过听诊器传播提供强大而有效的解决方案。
