| spinal anaesthetic | A local anaesthetic agent producing loss of sensation when injected into the subarachnoid space. (05 Mar 2000) |
|---|---|
| inhalation anaesthetic | A gas or a liquid with sufficient vapor pressure to produce general anaesthesia when breathed. (05 Mar 2000) |
| intravenous anaesthetic | A compound that produces anaesthesia when injected intravenously. (05 Mar 2000) |
| topical anaesthetic | An anaesthetic that is applied or sprayed on the surface of the skin (or mucous membranes) for providing pain relief. Commonly used are benzocaine, butacaine, cyclomethycaine, lidocaine, tetracaine and dibucaine. (27 Sep 1997) |
| epidural anaesthetic | 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) |
| flammable anaesthetic | An inhalation anaesthetic that supports combustion and forms explosive mixtures with oxidizing gases. (05 Mar 2000) |
| anaesthesia, local | Anaesthesia confined to one part of the body. Infiltration anaesthesia produces local anaesthesia by deposition of a local anaesthesia solution in the area of small, terminal nerve endings. (12 Dec 1998) |
| anaesthetics, local | Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fibre. In contact with a nerve trunk, these anaesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. Nearly all local anaesthetics act by reducing the tendency of voltage-dependent sodium channels to activate. They are commonly used not only in the peripheral nervous system, but also for spinal anaesthesia. The many drugs that have local anaesthetic actions as a side effect but are not used for their local anaesthetic action are not included here. (12 Dec 1998) |
| anti-infective agents, local | Substances used on humans and other animals that destroy harmful microorganisms or inhibit their activity. They are distinguished from disinfectants, which are used on inanimate objects. (12 Dec 1998) |
| neoplasm recurrence, local | The local recurrence of a neoplasm following treatment. It arises from microscopic cells of the original neoplasm that have escaped therapeutic intervention and later become clinically visible at the original site. (12 Dec 1998) |
| local | Restricted to or pertaining to one spot or part, not general. Origin: L. Localis (18 Nov 1997) |
| local anaemia | Anaemia resulting from a decreased supply of blood to a part, as in the occlusion of a vessel. (05 Mar 2000) |
| local anaesthesia | 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. Origin: Gr. Aisthesis = sensation (27 Sep 1997) |
| local anaphylaxis | The immediate, transient kind of response that follows the injection of antigen (allergen) into the skin of a sensitised individual and is limited to the area surrounding the site of inoculation. See: skin test. (05 Mar 2000) |
| local area networks | Communications networks connecting various hardware devices together within or between buildings by means of a continuous cable or voice data telephone system. (12 Dec 1998) |
