Hands, whether gloved or ungloved, are one of the main ways of spreading infection or for transferring microbial contamination. The usage of เจลล้างมือแอลกอฮอล์ 70 is part of the process of good contamination control for personnel working in hospital environments, or those involved with aseptic processing and within cleanrooms. Although there are various kinds of hand sanitizers available you can find differences with their effectiveness and lots of do not meet the European standard for hand sanitization.
Personnel doing work in medical centers and cleanrooms have many types of bacteria on their fingers etc bacteria can be readily transmitted from person to person or from person to gear or essential areas. Such bacteria are either present on the skin not multiplying (transient flora, which can include a range of environmental bacteria like Staphylococcus and Pseudomonas) or are multiplying bacteria launched from the skin (household flora including the genera of Staphylococcus, Micrococcus and Propionibacterium). Of these two groups, household flora tend to be more challenging to eliminate. For critical operations, some protection is afforded by putting on safety gloves. However gloves are not suitable for all activities and safety gloves, if not frequently sanitized or when they are of your unsuitable design, will pick up and transfer contamination.
Therefore, the sanitization of hands (either gloved or ungloved) is an essential part of contamination control either in medical centers, to avoid staff-to-patient cross contamination or prior to venture medical or surgical procedures; and for aseptic arrangements like the dispensing of medicines. Furthermore, not merely is using a hand sanitizer needed just before undertaking this kind of applications, it is also crucial that the sanitizer works well at eliminating a higher populace of bacteria. Studies show that in case a low variety of microorganisms continue after the application of a sanitizer then the subpopulation can develop which is immune to long term applications.
There are lots of commercially available hand sanitisers with all the most commonly used types being alcohol-based liquids or gels. Just like other types of disinfectants, hand sanitizers are effective against different เจลล้างมือแอลกอฮอล์ 70 depending upon their mode of activity. With the most frequent alcohol based hand sanitizers, the mode of action leads to bacterial cell death through cytoplasm leakage, denaturation of protein and eventual cell lysis (alcohols are one of the so-called ‘membrane disrupters’). The benefits of employing alcohols as hand sanitizers add a relatively low cost, little odour as well as a quick evaporation (limited residual activity results in shorter contact times). Furthermore alcohols use a proven cleansing action.
In selecting a hand sanitiser the pharmaceutical organisation or hospital will have to consider when the application is to be created to human skin or to gloved hands, or to both, and should it be needed to be sporicidal. Hand sanitisers fall into two groups: alcohol based, that are more widespread, and non-alcohol based. Such considerations impact both upon cost and also the safety and health from the staff utilizing the hand sanitiser since several commonly available alcohol based sanitisers can cause excessive drying on the skin; plus some non-alcohol based sanitisers can be irritating to the skin. Alcohol hand sanitizers are designed to avoid irritation through possessing hypoallergenic properties (colour and fragrance free) and ingredients which afford skin protection and care through re-fatting agents.
Alcohols possess a long background of use as เจลล้างมือแอลกอฮอล์ 70 because of inherent antiseptic properties against bacteria plus some viruses. To work water is needed to be mixed with alcohol to exert effect against microorganisms, with the most efficient range falling between 60 and 95% (most commercial hand sanitizers are around 70%). By far the most frequently used alcohol based apkdug sanitisers are Isopropyl alcohol or some form of denatured ethanol (including Industrial Methylated Spirits). The more common non-alcohol based sanitisers contain either chlorhexidine or hexachlorophene. Additives can even be contained in hand sanitizers in order to improve the antimicrobial properties.
Before entering a hospital ward or clean area hands ought to be washed using soap and water for about twenty seconds. Handwashing removes around 99% of transient microorgansisms (although it does not kill them) (4). From that point on, whether gloves are worn or otherwise, regular hygienic hand disinfection should occur to eliminate any subsequent transient flora and also to reduce the potential risk of the contamination as a result of resident skin flora.
