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 ...
As the iodine is used up, the dressing loses colour and becomes white. [5] It is typically held in place using gauze and then bandage material. [6] The polyethylene glycol provides a moist environment allowing the iodine to reach the wound. [4] After a few days the dressing has a tendency to dry out, and must be changed often.
Frequent use is not recommended in people with thyroid problems or who are taking lithium. [2] Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. [4] The recommended strength solution contains 10% Povidone, with total iodine species equaling 10,000 ppm or 1% total titratable iodine. [4]
USP Tincture of Iodine is defined in the U.S. National Formulary (NF) as containing in each 100 mL, 1.8 to 2.2 grams of elemental iodine, and 2.1 to 2.6 grams of sodium iodide. Alcohol is 50 mL, and the balance is purified water. This "2% free iodine" solution has 0.08 mol/L of I 2, which provides about 1 mg of free iodine per 0.05 mL drop. The ...
Structure of povidone-iodine complex, the most common antiseptic in use today Antiseptics can be subdivided into about eight classes of materials. These classes can be subdivided according to their mechanism of action: small molecules that indiscriminately react with organic compounds and kill microorganisms (peroxides, iodine, phenols) and ...
Medical iodophor (Chinese povidone-iodine solution) An iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or water-soluble polymers such as povidone (forming povidone-iodine), [1] [2] The result is a water-soluble material that releases free iodine when in solution.
Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
In 2000, the photos were rescanned at a higher resolution, yielding more than 65 gigabytes. The female cadaver was cut into slices at 0.33-millimeter intervals, resulting in some 40 gigabytes of data. The term "cut" is a bit of a misnomer, yet it is used to describe the process of grinding away the top surface of a specimen at regular intervals ...
