“…This promising disinfectant was shown to reduce bacterial levels on surfaces near patients to greater degree than a quaternary ammonium disinfectant in one study [ 43 ]. In another study, an electrolyzed water disinfectant significantly reduced MRSA, VRE and C. difficile spores in in-vitro experiments, and significantly reduced aerobic bacteria and C. difficile spores when sprayed onto medical equipment [ 44 ]. Spraying equipment was simple, required only approximately 15 s per application, and could be left to dry without wiping.…”

Experts agree that careful cleaning and disinfection of environmental surfaces are essential elements of effective infection prevention programs. However, traditional manual cleaning and disinfection practices in hospitals are often suboptimal. This is often due in part to a variety of personnel issues that many Environmental Services departments encounter. Failure to follow manufacturer’s recommendations for disinfectant use and lack of antimicrobial activity of some disinfectants against healthcare-associated pathogens may also affect the efficacy of disinfection practices.Improved hydrogen peroxide-based liquid surface disinfectants and a combination product containing peracetic acid and hydrogen peroxide are effective alternatives to disinfectants currently in widespread use, and electrolyzed water (hypochlorous acid) and cold atmospheric pressure plasma show potential for use in hospitals. Creating “self-disinfecting” surfaces by coating medical equipment with metals such as copper or silver, or applying liquid compounds that have persistent antimicrobial activity surfaces are additional strategies that require further investigation.Newer “no-touch” (automated) decontamination technologies include aerosol and vaporized hydrogen peroxide, mobile devices that emit continuous ultraviolet (UV-C) light, a pulsed-xenon UV light system, and use of high-intensity narrow-spectrum (405 nm) light. These “no-touch” technologies have been shown to reduce bacterial contamination of surfaces. A micro-condensation hydrogen peroxide system has been associated in multiple studies with reductions in healthcare-associated colonization or infection, while there is more limited evidence of infection reduction by the pulsed-xenon system. A recently completed prospective, randomized controlled trial of continuous UV-C light should help determine the extent to which this technology can reduce healthcare-associated colonization and infections.In conclusion, continued efforts to improve traditional manual disinfection of surfaces are needed. In addition, Environmental Services departments should consider the use of newer disinfectants and no-touch decontamination technologies to improve disinfection of surfaces in healthcare.

“…Several methods of disinfection have been demonstrated for disinfection purpose such as fluorescent dye and chemical germicides, that are used to disinfect and clean the environment which is still considered inadequate for proper disinfection [13,14]. The procedures for disinfection followed conventionally are still not up to the mark as it is still not adequate for proper disinfection specially for medical equipment such as the usage of fluorescent dye which shows improved cleaning and have led to reduction in healthcare-associated pathogenic infection [15]. Chemical germicides and fluorescent are not adequate enough to counter contamination.…”

Ultraviolet-C (UVC) sourced has been widely used for the purpose of disinfection due to its germicidal spectrum. In this study, the effectiveness of Everlight’s 275 nm Ultraviolet-C surface mounted device (UVC-SMD) to disinfect Staphylococcus aureus (S. aureus) was investigated at three exposure durations (10, 30 and 60 s) for a standard distance of 5 cm. The inhibition zones were greater with the increment of exposure duration. The highest records of 4.53 ± 0.03 cm were achieved when 102 mJ/cm² of dose was applied at a distance of 5 cm for 60 s. Whereas, on the other side, the lowest inhibition was seen when the exposure was set for 10 s. Thus, the Everlight 6565 UVC-SMD with 275 nm of wavelength is capable in providing bacterial disinfection which could possibly be used for the development of disinfection system based on SMDs at longer exposure duration.

As vantagens da água eletrolisada são que não requer a limpeza prévia da superfície, não deixa resíduos tóxicos nas superfícies e as desvantagens são as questões logísticas relacionadas à sua utilização, odor no ambiente, há poucos estudos disponíveis sobre sua eficácia e não disponibilidade no Brasil 20 .…”
