| anaesthesia | <anaesthetics, neurology> The loss of feeling or sensation. Although the term is used for loss of tactile sensibility or of any of the other senses, it is applied especially to loss of the sensation of pain, as it is induced to permit performance of surgery or other painful procedures. Origin: Gr. Aisthesis = sensation (13 Nov 1997) |
| anaesthesia adjuvants | Agents that are administered in association with anaesthetics to increase effectiveness, improve delivery, or decrease required dosage. (12 Dec 1998) |
| anaesthesia, caudal | Epidural anaesthesia administered via the sacral canal. (12 Dec 1998) |
| anaesthesia, closed-circuit | Inhalation anaesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anaesthetic gas and oxygen are added so that no anaesthetic escapes into the room. Closed-circuit anaesthesia is used especially with explosive anaesthetics to prevent fires where electrical sparking from instruments is possible. (12 Dec 1998) |
| anaesthesia department, hospital | Hospital department responsible for the administration of functions and activities pertaining to the delivery of anaesthetics. (12 Dec 1998) |
| anaesthesia dolorosa | Severe spontaneous pain occurring in an anaesthetic area. Synonym: painful anaesthesia. (05 Mar 2000) |
| anaesthesia, inhalation | Anaesthesia caused by the breathing of anaesthetic gases or vapors or by insufflating anaesthetic gases or vapors into the respiratory tract. (12 Dec 1998) |
| 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) |
| anaesthesia machine | Equipment used for inhalation anaesthesia, including flowmeters, vaporisers, and sources of compressed gases, but not including the anaesthetic circuit or mechanisms for elimination of carbon dioxide. (05 Mar 2000) |
| anaesthesia record | A written account of drugs administered, procedures undertaken, and physiologic responses during the course of surgical or obstetrical anaesthesia. (05 Mar 2000) |

| axillary anaesthesia | Loss of sensation in the distal two-thirds of the upper extremity following injection of a local anaesthetic solution about the nerve trunks in the axilla. (05 Mar 2000) |
| balanced anaesthesia | A technique of general anaesthesia based on the concept that administration of a mixture of small amounts of several neuronal depressants summates the advantages, but not the disadvantages of, the individual components of the mixture. (05 Mar 2000) |
| basal anaesthesia | Parenteral administration of one or more sedatives to produce a state of depressed consciousness short of a general anaesthesia. (05 Mar 2000) |
