| electric anaesthesia | Anaesthesia, usually general anaesthesia, produced by application of an electrical current. (05 Mar 2000) |
|---|---|
| to-and-fro anaesthesia | Anaesthesia using of a valveless closed anaesthesia circuit in which respired gases pass back and forth through a carbon dioxide absorbent interposed between patient and respiratory reservoir bag. (05 Mar 2000) |
| topical anaesthesia | Superficial loss of sensation in conjunctiva, mucous membranes or skin, produced by direct application of local anaesthetic solutions, ointments, or jellies. (05 Mar 2000) |
| total spinal anaesthesia | Spinal anaesthesia extensive enough to produce loss of sensation in all extracranial sensory roots. (05 Mar 2000) |
| endotracheal anaesthesia | Inhalation anaesthesia technique in which anaesthetic and respiratory gases pass through a tube placed in the trachea via the mouth or nose. Synonym: intratracheal anaesthesia. (05 Mar 2000) |
| traumatic anaesthesia | Loss of sensation resulting from nerve injury. (05 Mar 2000) |
| epidural anaesthesia | Regional anaesthesia produced by injection of local anaesthetic solution into the peridural space. Synonym: peridural anaesthesia. (05 Mar 2000) |
| extradural anaesthesia | Anaesthetization, by local anaesthetics, of nerves near the spinal canal external to the dura mater; often refers to epidural anaesthesia, but may include paravertebral anaesthesia. (05 Mar 2000) |
| unilateral anaesthesia | <neurology> The inability to feel touches (tactile sensations) on one side of the body. (09 Oct 1997) |
| field block anaesthesia | Conduction anaesthesia in which small nerves are not anaesthetised individually, as in nerve block anaesthesia, but instead are blocked en masse by local anaesthetic solution injected to form a barrier proximal to the operative site. (05 Mar 2000) |
| fractional epidural anaesthesia | Insertion of a catheter into the lumbar or caudal epidural space for the repeated injection of local anaesthetic solutions as a means of prolonging duration of anaesthesia. Synonym: fractional epidural anaesthesia. (05 Mar 2000) |
| fractional spinal anaesthesia | Insertion of a catheter into the spinal subarachnoid space and leaving it in situ to permit serial intermittent injection of local anaesthetic solution for prolonged spinal anaesthesia. Synonym: fractional spinal anaesthesia. (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) |
| low spinal anaesthesia | Spinal anaesthesia in which the level of sensory denervation extends to the tenth or eleventh thoracic dermatome. (05 Mar 2000) |
| abscess, skin | Medical term for a common boil. (12 Dec 1998) |
