a liquid anesthetic that at room temperature volatilizes to a vapor, which, when inhaled, is capable of producing general anesthesia.

(volă-til anes-thetik)
Liquid anesthetic that volatilizes to a vapor at room temperature and, when inhaled, is capable of producing general anesthesia.

anesthetic

1. pertaining to, characterized by, or producing anesthesia.
2. a drug or agent used to abolish the sensation of pain, to achieve adequate muscle relaxation during surgery, to calm fear and allay anxiety. See also anesthesia.

dissociative anesthetic
an anesthetic causing interruption of cerebral association pathways between the limbic system and cortical system. It produces a catalepsy-like state, in which the patient feels dissociated from its environment, and marked analgesia. Ketamine, phencyclidine and tiletamine hydrochloride are examples.
gaseous anesthetic
inhalation anesthesia. Halothane and isoflurane are commonly used agents.
general anesthetic
see general anesthesia.
anesthetic-induced rhabdomyolysis
see porcine stress syndrome.
inhalation anesthetic
gas or volatile liquid that produces general anesthesia when inhaled. The older agents, ether and cyclopropane, have been replaced by halothane, enflurane and isoflurane.
injectable anesthetic
sedative-hypnotic drugs produce anesthesia when administered in large doses. It can be administered intraperitoneally, but intravenous injection is much the most common route. Short-acting drugs, such as thiopentone, are used alone for very rapid procedures or for instrument examinations, or as induction for a longer term inhalation anesthetic. See also barbiturate. One anesthetic agent that is administered intramuscularly is ketamine.
irreversible anesthetic
the injection of a substance that destroys the peripheral nerve, e.g. ethyl or propyl alcohol.
local anesthetic
a drug that blocks nerve transmission in the nerves affected by the local presence of the drug. It may be applied topically, e.g. into the conjunctival sac, or by injection into tissues near the target nerve. Most local anesthetics are in the -caine series.
anesthetic machine
apparatus or equipment used to administer gaseous anesthetic agents; functions of the apparatus should include,
1. delivery of oxygen,
2. removal of carbon dioxide,
3. quantifiable delivery of anesthetic vapor or gas, and
4. capability of providing artificial respiration to the patient.
anesthetic scavenging
the use of any device to reduce the pollution of the air in surgeries caused by exhaled anesthetic gases. May be canisters of filtering material attached to the machine or suction lines at stragetic positions in the theater.
volatile anesthetic
see inhalation anesthetic (above).

volatile

evaporating rapidly.

volatile anesthetic
see inhalation anesthetic.
volatile fatty acids
short-chain, soluble in water and steam-distillable; acetic, butyric, propionic acids. See also fatty acids.

Contract Award Notice: This Framework Agreement is for the supply of Desflurane Volatile Anaesthetic Gas to NHS Scotland, including the loan of vaporisers for use with Desflurane.
Current guidelines are for a 60 minute O2 flush at 10 litres/minute due to the multiple plastic components that absorb volatile anaesthetic vapours.
Of particular interest to anaesthetists, recent data suggests that volatile anaesthetic agents as well as propofol both interact with the mPTP during ischaemia-reperfusion and attenuate mitochondrial permeability transition, thus ameliorating the flow-on effects of necrotic cell death.
Once absorbed into the circulation by the lungs, the uptake of volatile anaesthetic by various body tissues is influenced by tissue blood flow and body mass.

The chin touching experiment involved a number of alterations to the paradigm used in Goldmann's earlier studies: firstly, chin touching rather than ear touching was used as the target behaviour, as ear touching seemed to be a comparatively infrequent behaviour for British patients; secondly, the suggestions were preceded by the patient's name, as Bennett had suggested this may be crucial; thirdly, although some patients received a volatile anaesthetic, the message was presented near the end of (cardiopulmonary) surgery when all patients were inhaling 100 per cent oxygen.
Contract Award Notice: This Framework Agreement is for the supply of Sevoflurane and Isoflurane Volatile Anaesthetic Gases to NHS Scotland, including the loan of vaporisers for use with Sevoflurane for the duration of the framework agreement.
Data segments were collected from the midpoint of the anaesthetic and from a point five minutes before the anaesthetists turned off the vapouriser and washed out the volatile anaesthetic agent.
Use of pupil size, lacrimation, sweating and cardiovascular parameters alone are poor predictors of the depth of anaesthesia (Hadzidiakos et al 2006) and measurement of end tidal volatile anaesthetic agent concentration (ETAA) has become standard anaesthetic practice in the United Kingdom.
Drugs included: analgesics, induction agents, neuromuscular blockers and volatile anaesthetic agents; consumables/fluids included intravenous cannulae and tubing, commonly used intra-operative fluids, and airways (Appendix A).
