Evaluate the presence of bacteria and resistance profile in stethoscopes used by health care professionals and its consequences within the hospital environment.
It is a systematic review, in which articles indexed in the BVS, CAPES-Periódicos, Cochrane Library, PubMed, Scientific Electronic Library Online, and ScienceDirect databases were searched.
Twenty-two articles were selected for this study. The significant majority of professionals does not perform hygiene of the stethoscope, either due to the lack of instructions or the lack of knowledge about the contamination's risks. In addition, over these 22 articles evaluated, only 10 demonstrated that more than 50% of the analyzed samples were contaminated with some type of bacteria. Coagulase-negative Staphylococcus spp., Staphylococcus aureus, Acinetobacter spp., Pseudomonas spp., and Klebsiella pneumoniae were the most recurrent pathogens. Besides that, multiresistant strains were also isolated, highlighting resistance to Ampicillin and Clindamycin.
Indeed, the stethoscope is a potential disseminator of bacterial infections. The contamination is explained by the possible cross reactions that make the transmission of infectious agents possible. Cleaning before and after each auscultate is an efficient alternative to minimize these pathogens.
评估医护人员使用的听诊器中存在的细菌及其在医院环境中的耐药情况。
这是一项系统评价，在 BVS、Capes-Periódicos、Cochrane 图书馆、PubMed、科学电子图书馆在线和 ScienceDirect 数据库中搜索了相关文章。
共选择了 22 篇文章进行研究。大多数专业人员没有对听诊器进行卫生清洁，要么是因为缺乏指导，要么是因为缺乏对污染风险的认识。此外，在所评估的 22 篇文章中，只有 10 篇表明超过 50%的分析样本被某种类型的细菌污染。凝固酶阴性葡萄球菌、金黄色葡萄球菌、不动杆菌属、铜绿假单胞菌和肺炎克雷伯菌是最常见的病原体。此外，还分离出了多耐药菌株，对氨苄西林和克林霉素的耐药性尤为突出。
事实上，听诊器是细菌感染的潜在传播者。污染是由可能的交叉反应引起的，这些交叉反应使传染性病原体的传播成为可能。在每次听诊前后进行清洁是一种有效的方法，可以最大限度地减少这些病原体。
