The objectives of our study were to study the stethoscope cleaning practices of medical personnel and to assess the microbial load on stethoscopes and efficacy of cleaning stethoscopes with alcohol-based disinfectant.
A questionnaire-based cross-sectional study was conducted among medical personnel at a tertiary care hospital in India to assess their knowledge and cleaning practices regarding stethoscope disinfection. Samples from the stethoscopes were collected before and after cleaning with alcohol-based disinfectant.
Out of 62 participants, 53.22% individuals had never cleaned their stethoscope. All the initial swab samples showed bacterial growth. There was mixed growth in the samples taken from 35 stethoscope bells and 31 diaphragms. Bacteria included coagulase negative staphylococci, bacillus species, diptheroids, and After cleaning with an alcohol-based disinfectant, there was a significant decrease in the average number of bacterial colony-forming units.
Regular cleaning practices should be followed to prevent growth and transmission of potentially pathogenic organisms.
我们研究的目的是调查医务人员对听诊器的清洁习惯，评估听诊器上的微生物负荷以及酒精基消毒剂清洁听诊器的效果。
在印度一家三级护理医院对医务人员进行了一项基于问卷的横断面研究，以评估他们关于听诊器消毒的知识和清洁习惯。在用酒精基消毒剂清洁前后，从听诊器上采集样本。
在62名参与者中，53.22%的人从未清洁过他们的听诊器。所有初始拭子样本均显示有细菌生长。从35个听诊器钟型体和31个膜片采集的样本中有混合生长。细菌包括凝固酶阴性葡萄球菌、芽孢杆菌属、类白喉杆菌等。在用酒精基消毒剂清洁后，细菌菌落形成单位的平均数显著下降。
应遵循定期清洁习惯，以防止潜在致病生物的生长和传播。
