Iodoform stored in an ampoule. Iodoform (also known as triiodomethane) is the organoiodine compound with the chemical formula C H I 3.It is a pale yellow, crystalline, volatile substance, with a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as that of hospitals, where the compound is still commonly used) and, analogous to chloroform, sweetish taste.
Pressure is thus induced while the capillary action of the improvised gauze-sac secures drainage. [citation needed] It was developed by Polish surgeon Jan Mikulicz-Radecki (1850-1905) as a means to drain the abdominal cavity after an operation. In the past, the gauze was treated with iodoform as an antiseptic. [2]
Examples of medicated dressings include antibacterials, topical anesthetics and obtundants, or combinations of all three, e.g., zinc oxide and eugenol impregnated cotton pellets, alvogyl (eugenol, iodoform and butamben), dentalone, bismuth subnitrate and iodoform paste (BIPP) on ribbon gauze and metronidazole and lidocaine ointment.
For persons with a dry socket as a complication of tooth extraction, packing the dry socket with a eugenol-zinc oxide paste on iodoform gauze is effective for reducing acute pain. [3] The placement of a ZOE "temporary" for a few to several days prior to the placement of the final filling can help to sedate the pulp.
For persons with a dry socket as a complication of tooth extraction, packing the dry socket with a eugenol-zinc oxide paste on iodoform gauze is effective for reducing acute pain. [21] Eugenol-zinc oxide paste is also used for root canal sealing. [22]
One of the more well-known uses of organoiodine compounds is the so-called iodoform test, where iodoform (CHI 3) is produced by the exhaustive iodination of a methyl ketone (or another compound capable of being oxidised to a methyl ketone), as follows: [26]
DEIR AL-BALAH, Gaza Strip (Reuters) - After surviving on bitter loaves made from animal feed instead of proper flour, three young brothers who fled their home in Gaza City for a tent further south ...
Structured packing is formed from corrugated sheets of perforated embossed metal, plastic, or wire gauze. The result is a very open honeycomb structure with inclined corrugations or flow channels, giving a relatively high surface area but with very low resistance to gas flow. The surface enhancements have been chosen to maximize liquid spreading.
