Disinfectant and antiseptics pdf Continue Antiseptics and disinfectants are very similar in that they are both used to kill microorganisms. They differ from each other, albeit in the composition of them, as well as their use. Antiseptics are used on living organisms, such as human skin, to kill any microorganisms living on the surface of the body. Disinfectants are used on non-living things such as countertops and handrails to kill microorganisms living on this inanimate surface. Antiseptics tend to have a lower concentration of a particular biocide, which is used in this product to clean the surface than that of a disinfectant. Since disinfectants are not intended for use on living tissues, but rather inanimate surfaces, they can use a higher concentration of biocide in the product, since there is no skin or tissue to worry about irritants. Antiseptics require a lower concentration of biocides, as too high concentrations of some biocides can cause a large amount of skin irritation. Some examples of antiseptics are mouthwash or hand sanitizer, both of which are safe for contact with your skin and also capable of being extremely effective in killing large numbers of microorganisms. Alcohol, bleach and formaldehyde are examples of various types of disinfectants used to kill microorganisms on the surface of any non-living objects. It is important that people know the difference between antiseptics and disinfectants, as they are both used for similar things, but in different ways. The use of disinfectant as an antiseptic is likely to irritate this tissue. In addition, the use of antiseptic as a disinfectant may result in less sufficient work to clean this surface due to the lower concentration of the biocide. Sources: Hermicide redirects here. For the Germs album, see Germicide (album). Not to be confused with an antibiotic. Antiseptics (from Greek ἀντί anti, cons and s'ptikos, putrefactive () are antimicrobials that are applied to living tissue/skin to reduce the likelihood of infection, Antiseptics tend to differ from antibiotics by the latter's ability to safely destroy bacteria in the body, and from disinfectants that destroy microorganisms found on non-living objects. Microbicides, destroying viral particles, are called viricides or antiviral drugs. Antifungal drugs, also known as antimicrobies, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection). Surgery Joseph Lister Widespread Antiseptic surgical techniques were initiated in 1867 by Joseph Lister of the paper antiseptic principle of surgery practice, which was inspired by the theory of the rottenness of Louis Pasteur. In this article, Lister advocated the use of carbolic acid (phenol) as a method to ensure that all present microbes were killed. Some of these works were expected: ancient Greek doctors Galen (about 130-200) and Hippocrates (circa 400 BC) and Sumerian clay tablets, starting in 2150 BC, who advocate the use of similar methods. Medieval surgeons Hugh Lucca, Theoderic Servia, and his pupil Henri de Mondeville were opponents of Galen's view that the pea was essential for healing, leading ancient and medieval surgeons to let the pistric remain in the wounds. They advocated draining and cleaning the edges of the wound with wine, dressing the wound after soaking, if necessary and leaving the bandage for ten days, soaking it in warm wine all the time before changing it. Their theories were bitterly opposed by the gallinist Guy de Sholjak and others trained in classical tradition. Oliver Wendell Holmes Sr., who published The Contagion of Puerperal Fever in 1843, Florence Nightingale, contributed significantly to the report of the Royal Commission on Army Health (1856- 1857), based on her previous work by Ignaz Semmelweis, who published his work Cause, Concept and Prevention of Pediatric Fever in 1861, summing up experiments and observations from 1847, the most common antiseptic in use today. Antiseptics can be divided into about eight classes of materials. These classes can be subdiminated according to their mechanism of action: small molecules that react indescribably with organic compounds and kill microorganisms (peroxide, iodine, phenols) and more complex molecules that disrupt the cell walls of bacteria. Phenols such as phenol (as introduced by Lister) and triclosan, hexachlorofen, chlorocresol and chloroxylenol. The latter is used to disinfect the skin and clean surgical instruments. It is also used in a number of household disinfectants and wound cleaners. Diguanides including chlorhexidine gluconate, a bacteriotic antiseptic that (with alcoholic solvent) is most effective in reducing the risk of infection after surgery. It is also used in mouthwash to treat gum inflammation (gingivitis). Polyhexanin (polyhexamethylene biguard, FMB) is an antimicrobial compound suitable for clinical use in critically colonized or infected acute and chronic wounds. The physical effect on the bacterial membrane prevents or prevents the development of resistant bacterial strains. quinolins such as hydroxyquinolone, chloride decvalia or Alcohol including ethanol ethanol 2-propanol/isopropanol is sometimes called surgical spirit. They are used to disinfect the skin before injections, among other uses. Peroxide such as hydrogen peroxide and benzoyl peroxide. Generally, 3% of hydrogen peroxide solutions have been used in home first aid for scratches, etc. However, strong oxidation causes scarring and increases healing time during fetal development. Iodine, especially in the form of povidano-iodine, is widely used because it is well tolerated, does not have a negative effect on wound healing, leaves the deposition of active iodine, thus creating the so-called residue, or persistent, effect, and has a wide range of antimicrobial activity. Traditional iodine antiseptic is analochol solution (so-called iodine tincture) or Lugol iodine solution. Some studies do not recommend disinfecting minor wounds with iodine for fear that it may cause scar tissue to form and increase healing time. However, concentrations of 1% of iodine or less have not been shown to increase healing time and do not differ from the treatment of saline solution. Iod will kill all major pathogens and, given sufficient time, even spores, which are considered the most complex form of microorganisms, to be inactivated by disinfectants and antiseptics. Dihydrochloride Oktenidine, which is now increasingly used in continental Europe, is often used as a substitute for chlorhexidine. Kvat salts such as benzalconium chloride, chloride cethyrididinia or cetrimide. These surfactants destroy cell walls.
