Healthcare-related infections are sustained by various bacteria and fungi. In recent years, various technologies have emerged for the sanitation of healthcare-related environments. This study evaluated the effectiveness of a no-touch disinfection system that aerosolizes 5% hydrogen peroxide and 10% ethyl alcohol. After selecting an environment, the Total Bacterial Count and the Total Fungal Count in the air and on a surface of the room were determined to evaluate the effectiveness of the aerosolization system. In addition, sterile stainless-steel plates inoculated with , , and spp. isolated from hospitalized patients and reference strains were used to evaluate the effectiveness of the system. For each organism, three plates were used: A (cleaned), B (not cleaned), and C (control). The A plates were treated with non-ionic surfactant and the aerosolization system, the B plates were subjected to the aerosolization system, and the plates C were positioned outside the room that was sanitized. Following sanitization, air and surface sampling was conducted, after which, swabs were processed for bacterial and fungal enumeration. The results showed that the air sanitization system had good efficacy for both bacteria and fungi in the air and on stainless-steel plates, particularly for the A plates.
与医疗保健相关的感染是由各种细菌和真菌引起的。近年来，出现了各种用于医疗保健环境清洁的技术。本研究评估了一种将 5%过氧化氢和 10%乙醇气溶胶化的无接触消毒系统的有效性。在选择环境后，确定空气中和房间表面的总细菌计数和总真菌计数，以评估气溶胶化系统的有效性。此外，还使用从住院患者和参考菌株中分离出的 和 spp. 无菌不锈钢板来评估该系统的有效性。对于每种生物体，使用三个平板：A（清洁）、B（未清洁）和 C（对照）。平板 A 用非离子表面活性剂和雾化系统处理，平板 B 用雾化系统处理，平板 C 放在已消毒房间的外面。消毒后，进行空气和表面采样，然后对拭子进行细菌和真菌计数处理。结果表明，空气消毒系统对空气中和不锈钢平板上的细菌和真菌都具有良好的效果，特别是对平板 A。
