Povidone-iodine (PVP-I), also known as iodopovidone, is an antiseptic used for skin disinfection before and after surgery. [1] [2] It may be used both to disinfect the hands of healthcare providers and the skin of the person they are caring for. [2] It may also be used for minor wounds. [2] It may be applied to the skin as a liquid, an ointment ...
Iodine is a chemical element with many uses in medicine, depending on the form. Elemental iodine and iodophors are topical antiseptics. [2] Iodine, in non-elemental form, functions as an essential nutrient in human biology (see iodine in biology). [3] Organic compounds containing iodine are also useful iodinated contrast agents in X-ray imaging ...
Skin disinfection may be accomplished with a number of solutions including providone-iodine, chlorhexidine, alcohol based solutions, and cetrimide. [2] There is strong evidence that chlorhexidine and denatured alcohol use to clean skin prior to surgery is better than any other commercially available antiseptic, such as povidone-iodine with alcohol.
Tincture of iodine, iodine tincture, or weak iodine solution is an antiseptic. It is usually 2 to 3% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water. Tincture solutions are characterized by the presence of alcohol.
Iodine will kill all principal pathogens and, given enough time, even spores, which are considered to be the most difficult form of microorganisms to be inactivated by disinfectants and antiseptics. Octenidine dihydrochloride , currently increasingly used in continental Europe, often as a chlorhexidine substitute.
As antiseptics (i.e., germicide agents that can be used on human or animal body, skin, mucosae, wounds and the like), few of the above-mentioned disinfectants can be used, under proper conditions (mainly concentration, pH, temperature and toxicity toward humans and animals). Among them, some important are
The three major antimicrobial compounds containing iodine are alcohol-iodine solution, an aqueous solution of iodine, and iodophors. Iodophors are more bactericidal and are used as antiseptics as they are less irritating when applied to the skin. Bacterial spores on the other hand cannot be killed by iodine, but they can be inhibited by iodophors.
Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8] Lugol's iodine was first made in 1829 by the French physician Jean Lugol. [7] [8] It is on the World Health Organization's List of Essential Medicines. [9] [10] Lugol's iodine is available as a generic medication and over the ...
