ethylene (redirected from Ethylenes)

ethylene /eth·y·lene/ (eth´ĭ-lēn) a colorless flammable gas, CH2dbondCH2, with a slightly sweet odor and taste; formerly used as an inhalation anesthetic.

ethylene dibromide  a fumigant and gasoline additive; it is a skin and mucous membrane irritant and is carcinogenic.

ethylene dichloride  a solvent, gasoline additive, and intermediate; it is irritating and toxic, and can be carcinogenic.

ethylene glycol  a solvent used as an antifreeze; ingestion can cause central nervous system depression, vomiting, hypotension, coma, convulsions, and death.

ethylene oxide  a gas used in manufacturing organic compounds and as a fumigant, fungicide, and sterilizing agent; it is highly irritating to the eyes and mucous membranes and is carcinogenic.

eth·yl·ene (th-ln)

n.

1. An explosive gas derived from natural gas and petroleum infrequently used as an inhalation anesthetic. Also called ethene.

2. The bivalent hydrocarbon radical C₂H₄ that is isomeric to the ethylidene radical.

ethylene

[eth′əlēn]

Etymology: Gk, aither, air, hyle, stuff

a colorless flammable gas that is just lighter than air and has a slightly sweet odor and taste. It was previously used as a general anesthetic and is slightly more potent than nitrous oxide. Also called ethene, olefiant gas.

ethylene (eth´ilēn),

n (olefiant gas, CH₂CH₂) a colorless gas of slightly sweet odor and taste; used as an inhalation anesthetic.

ethylene oxide sterilization,

n a process that uses gas to sterilize instruments, equipment, and materials that would otherwise be damaged by heat or liquid chemicals. Effective at room temperature. Requires between 10 and 16 hours to be effective. Gas must penetrate the material. The gas is highly toxic and must be vented before opening the sealed sterilizing unit. Sterilized materials must also be well aerated before using.

etidocaine HCl (local),

n brand names: Duranest, Duranest MPF;
drug class: amide, local anesthetic;
action: inhibits ion fluxes across membranes, particularly sodium transport across cell membrane; decreases rise of depolarization phase of action potential; blocks nerve action potential;
uses: local dental anesthetic, peripheral nerve block, caudal anesthetic, central neural block, vaginal block.

ethylene

a colorless, highly flammable gas with a slightly sweet taste and odor, used as an inhalation anesthetic to induce general anesthesia.

ethylene dibromide (EDB)

grain fumigant. Treated seed seriously reduces egg production when fed to hens in very small amounts.

ethylene dichloride

industrial fumigant; causes respiratory and ophthalmic irritation, narcosis, disturbance of equilibrium.

ethylene glycol

antifreeze; palatable enough for animals to drink in quantity. Causes ataxia, depression, coma, polydipsia, vomiting and convulsions due to formation of oxalate crystals in brain blood vessels and renal tubules.

ethylene oxide

a fumigant used for foodstuffs, surgical equipment and as an agricultural fungicide. It is a gaseous, flammable alkylating agent with a broad spectrum of activity, being sporicidal and viricidal. It is used (mixed with CO₂ or fluorocarbons because it is explosive above 3%) for disinfecting and sterilizing equipment and instruments that are used in the hospital, surgery, dentistry, and the pharmaceutical and other industries, and that are thermolabile or will be adversely affected by immersion in water or other media. Its optimal germicidal effect occurs after a 3-hour exposure at 86°F (30°C). Its vapor is irritating to eyes and respiratory mucosa and can cause serious pulmonary edema. Called also oxirane.
