Hands, whether gloved or ungloved, are some of the main means of spreading infection or for transferring microbial contamination. Using เจลล้างมือแอลกอฮอล์ 70 is part of the process of good contamination control for personnel working in hospital environments, or those involved in aseptic processing and within cleanrooms. Although there are many different types of hand sanitizers available there are differences with their usefulness and lots of do not meet the European standard for hand sanitization.
Staff employed in medical centers and cleanrooms have various types of microorganisms on the fingers etc microorganisms can be easily transmitted for every person or from person to equipment or critical areas. Such bacteria are either present on the skin area not multiplying (transient flora, which can incorporate a range of environmental bacteria like Staphylococcus and Pseudomonas) or are multiplying bacteria released through the skin (household flora like the genera of Staphylococcus, Micrococcus and Propionibacterium). Of the two organizations, household flora are more challenging to remove. For essential procedures, some protection is afforded by putting on gloves. Nevertheless gloves usually are not ideal for all activities and safety gloves, or even regularly sanitized or when they are of your unsuitable design, will pick up and transfer toxic contamination.
Consequently, the sanitization of hands (either gloved or ungloved) is an integral part of toxic contamination manage either in medical centers, to prevent staff-to-patient go across contamination or prior to undertaking medical or surgical operations; and for aseptic arrangements like the dispensing of medications. Moreover, not merely is utilizing a hand sanitizer required prior to undertaking this kind of applications, additionally it is crucial that the sanitizer is useful at eliminating a high populace of microorganisms. Studies show that if a small number of bacteria persist right after the use of a sanitizer then the subpopulation can build that is immune to long term programs.
There are numerous commercially available hand sanitisers using the most frequently used types being alcohol-based liquids or gels. Similar to other types of disinfectants, hand sanitizers work well against different เจลล้างมือแอลกอฮอล์ based on their mode of activity. With the most typical 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 advantages 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 have a proven cleansing action.
When deciding on a hand sanitiser the pharmaceutical organisation or hospital should consider if the application is going to be made to human skin or to gloved hands, or both, and when it is required to be sporicidal. Hand sanitisers fall into two groups: alcohol based, which are more widespread, and non-alcohol based. Such considerations impact both upon cost and also the safety and health from the staff making use of the hand sanitiser since several commonly available alcohol based sanitisers can cause excessive drying of your skin; and some non-alcohol based sanitisers can be irritating towards 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 history of use as เจลล้างมือแอลกอฮอล์ 70 due to inherent antiseptic properties against bacteria and some viruses. To be effective some water is required to be combined with alcohol to exert effect against microorganisms, with the most effective range falling between 60 and 95% (most commercial hand sanitizers are around 70%). The most frequently used alcohol based apkdug sanitisers are Isopropyl alcohol or some form of denatured ethanol (such as Industrial Methylated Spirits). The better common non-alcohol based sanitisers contain either chlorhexidine or hexachlorophene. Additives can also be contained in hand sanitizers in order to increase the antimicrobial properties.
Before entering a hospital ward or clean area hands needs to be washed using soapy water for around twenty seconds. Handwashing removes around 99% of transient microorgansisms (although it fails to kill them) (4). From then on, whether gloves are worn or not, regular hygienic hand disinfection should occur to remove any subsequent transient flora as well as reduce the chance of the contamination arising from resident skin flora.
