ether

 [e´ther]
1. an organic compound containing an oxygen atom bonded to two carbon atoms.
2. diethyl or ethyl ether: a colorless, transparent, mobile, very volatile, highly flammable liquid with a characteristic odor; it was the first inhalational anesthetic used for surgical anesthesia, but is now rarely used in the United States or Canada because of its flammability.

e·ther

(ē'thĕr),
1. Any organic compound in which two carbon atoms are independently linked to a common oxygen atom, thus containing the group -C-O-C-.
See also: epoxy.
2. Loosely used to refer to diethyl ether or an anesthetic ether, although a large number of ethers have anesthetic properties. For individual ethers, see the specific name.

ether

A volatile and highly inflammable liquid once widely used as a safe and effective drug for the induction and continuance of general anaesthesia. Induction is slow and unpleasant and deep anaesthesia is needed for muscle relaxation. Postoperative nausea is common. Because of these disadvantages and the danger of explosion, ether is now seldom used. The drug is, however, on the WHO official list.

ether

a general term for a group of anaesthesia-inducing volatile compounds

ether (ēˑ·thr),

n organic compound with molecule containing oxygen atom bonded to two hydrocarbon chains; insoluble in water but soluble in organic solvents such as ether and alcohol. Used as an early anaesthetic.
