| surgical anaesthesia | Any anaesthesia administered for the purpose of permitting performance of an operative procedure, as differentiated from obstetrical, diagnostic, and therapeutic anaesthesia, loss of sensation with muscle relaxation adequate for an operative procedure. (05 Mar 2000) |

| dental anaesthesia | <anaesthetics, dentistry> General, conduction, local, or topical anaesthesia for operations upon the teeth, gingivae, or associated structures. (05 Mar 2000) |
| diagnostic anaesthesia | Anaesthesia induced for evaluation of the mechanism responsible for a painful condition. (05 Mar 2000) |
| differential spinal anaesthesia | A form of diagnostic spinal anaesthesia producing blockade of different types of nerves in the subarachnoid space, based upon their differences in sensitivity to local anaesthetics; also observed during surgical spinal anaesthesia. (05 Mar 2000) |
| dissociated anaesthesia | Loss of some types of sensation with persistence of others; most often used in context of nerve blocks, wherein a loss of sensation for pain and temperature occurs without loss of tactile sense. (05 Mar 2000) |
| dissociative anaesthesia | A form of general anaesthesia, but not necessarily complete unconsciousness, characterised by catalepsy, catatonia, and amnesia, especially that produced by phenylcyclohexylamine compounds, including ketamine. (05 Mar 2000) |
| infiltration anaesthesia | Anaesthesia produced by injection of local anaesthetic solution directly into an area that is painful or about to be operated upon. (05 Mar 2000) |
| inhalation anaesthesia | General anaesthesia resulting from breathing of anaesthetic gases or vapors. (05 Mar 2000) |
| insufflation anaesthesia | Maintenance of inhalation anaesthesia by delivery of anaesthetic gases or vapors directly to the airway of a spontaneously breathing patient. (05 Mar 2000) |
| intercostal anaesthesia | Regional anaesthesia produced by injection of local anaesthetic solution about intercostal nerves. (05 Mar 2000) |
| intramedullary anaesthesia | Rarely used method of general anaesthesia by injection of intravenous anaesthetic agent(s) into the medullary canal of long bones. Synonym: intraosseous anaesthesia. (05 Mar 2000) |
| intranasal anaesthesia | Insufflation anaesthesia in which an inhalation anaesthetic is added to inhaled air passing through the nose or nasopharynx; anaesthesia of nasal passages by infiltration and topical application of local anaesthetic solution to nasal mucosa. (05 Mar 2000) |
| intraoral anaesthesia | Insufflation anaesthesia in which an inhalation anaesthetic is added to inhaled air passing through the mouth; regional anaesthesia of the mouth and associated structures when local anaesthetic solutions are used by topical application to oral mucosa, by local infiltration, or as nerve blocks. (05 Mar 2000) |
| intraosseous anaesthesia | Rarely used method of general anaesthesia by injection of intravenous anaesthetic agent(s) into the medullary canal of long bones. Synonym: intraosseous anaesthesia. (05 Mar 2000) |
| intraspinal anaesthesia | Inaccurate synonym for spinal anaesthesia; local anaesthetic solutions are not injected into the spinal cord. (05 Mar 2000) |
