| local anaesthetic | The use of a local anaesthetic (usually injected into the tissue) results in a small region of anaesthesia (numbness). Lidocaine (Xylocaine) or (Marcaine) are commonly used. (27 Sep 1997) |
|---|---|
| local anaesthetic reaction | A toxic reaction due to absorption of local anaesthetic drug during regional anaesthesia, ranging from drowsiness to convulsions and cardiovascular collapse. (05 Mar 2000) |
| local anaesthetics | Drugs used for the interruption of the nerve transmission of pain sensations. They act at the site of application to prevent perception of pain; examples include procaine and lidocaine. (05 Mar 2000) |
| anaesthetic | 1. <neurology> Pertaining to, characterised by or producing anaesthesia. 2. <pharmacology> A drug or agent that is used to produce partial loss of feeling or sensation of pain. (14 May 1997) |
|---|---|
| anaesthetic circuit | Equipment used during inhalation anaesthesia to regulate concentrations of inhaled gases; includes a reservoir bag and usually directional valves, breathing tubes, and a carbon dioxide absorber. (05 Mar 2000) |
| anaesthetic depth | The degree of central nervous system depression produced by a general anaesthetic agent; a function of potency of the anaesthetic and the concentration in which it is administered. (05 Mar 2000) |
| anaesthetic, epidural | An anaesthetic injected into the epidural space surrounding the fluid-filled sac (the dura) around the spine which partially numbs the abdomen and legs. (12 Dec 1998) |
| anaesthetic ether | General designation for many ether's. (05 Mar 2000) |
| anaesthetic gas | A gas or a liquid with sufficient vapor pressure to produce general anaesthesia when breathed. (05 Mar 2000) |
| anaesthetic index | Ratio of the number of units of anaesthetic required for anaesthesia to the number of units of anaesthetic required to produce respiratory or cardiovascular failure. (05 Mar 2000) |
| anaesthetic leprosy | A form of leprosy chiefly affecting the nerves, marked by hyperesthesia succeeded by anaesthesia, and by paralysis, ulceration, and various trophic disturbances, terminating in gangrene and mutilation. Synonym: Danielssen's disease, Danielssen-Boeck disease, dry leprosy, trophoneurotic leprosy. (05 Mar 2000) |
| anaesthetic shock | Shock produced by the administration of anaesthetic drug(s), usually in relative overdosage. (05 Mar 2000) |
| anaesthetic vapor | The gaseous phase of a liquid anaesthetic with sufficient partial pressure at room temperature to produce general anaesthesia when inhaled. (05 Mar 2000) |
| general anaesthetic | A compound that produces loss of sensation associated with loss of consciousness. (05 Mar 2000) |
| volatile anaesthetic | A liquid anaesthetic that at room temperature volatilises to a vapor which when inhaled is capable of producing general anaesthesia. See: anaesthetic vapor. (05 Mar 2000) |
| minimal anaesthetic concentration | The end-alveolar concentration of an inhalation anaesthetic which prevents somatic response to a painful stimulus in 50% of individuals; an index of relative potency of inhalation anaesthetics. Synonym: minimal anaesthetic concentration. (05 Mar 2000) |
| primary anaesthetic | The compound that contributes most to loss of sensation when a mixture of anaesthetics is administered. (05 Mar 2000) |
| secondary anaesthetic | A compound that contributes to, but is not primarily responsible for, loss of sensation when two or more anaesthetics are simultaneously administered. (05 Mar 2000) |
