| saddle anaesthesia | A form of spinal anaesthesia limited in area to the buttocks, perineum, and inner surfaces of the thighs. Synonym: saddle anaesthesia. (05 Mar 2000) |
|---|---|
| saddle block anaesthesia | A form of spinal anaesthesia limited in area to the buttocks, perineum, and inner surfaces of the thighs. Synonym: saddle anaesthesia. (05 Mar 2000) |
| high spinal anaesthesia | Spinal anaesthesia in which the level of sensory denervation extends to the second or third thoracic dermatome. (05 Mar 2000) |
| pudendal anaesthesia | Local anaesthesia produced by blocking the pudendal nerves near the spinal processes of the ischium; used in obstetrics. (05 Mar 2000) |
| segmental anaesthesia | Loss of sensation limited to an area supplied by one or more spinal nerve roots. (05 Mar 2000) |
| semi-closed anaesthesia | Inhalation anaesthesia using a circuit in which a portion of the exhaled air is exhausted from the circuit and a portion is rebreathed following absorption of carbon dioxide. (05 Mar 2000) |
| semi-open anaesthesia | <anaesthetics> Inhalation anaesthesia in which a portion of inhaled gases is derived from an anaesthesia circuit while the remainder consists of room air. (05 Mar 2000) |
| hydrate microcrystal theory of anaesthesia | A theory of narcosis pertaining to nonhydrogen-bonding agents; postulates the interaction of the molecules of the anaesthetic drug with water molecules in the brain. Synonym: Pauling's theory. (05 Mar 2000) |
| hyperbaric anaesthesia | Inhalation of depressant gases or vapors at pressures greater than 1 atmosphere, especially as a means of producing general anaesthesia with agents too weak to produce anaesthesia at 1 atmosphere. (05 Mar 2000) |
| hyperbaric spinal anaesthesia | Spinal anaesthesia in which spread of local anaesthetic solution in the subarachnoid space is controlled by adjusting the position of the patient when the density of local anaesthetic is made greater than the density of cerebrospinal fluid (i.e., hyperbaric) by the addition of glucose. (05 Mar 2000) |
| hypobaric spinal anaesthesia | <anaesthetics> Spinal anaesthesia in which spread of local anaesthetic solution in the subarachnoid space is controlled by adjusting the position of the patient when the density of the local anaesthetic solution is made less than the density of cerebrospinal fluid (i.e., hypobaric) by the addition of distilled water. (05 Mar 2000) |
| hypotensive anaesthesia | Anaesthesia in which arterial hypotension is deliberately induced as a means of decreasing operative blood loss. (05 Mar 2000) |
| hypothermic anaesthesia | General anaesthesia administered in conjunction with artificial lowering of body temperature. (05 Mar 2000) |
| hysterical anaesthesia | Anaesthesia as a manifestation of hysteria, usually involving half the body or isolated patches not conforming to neuroanatomical distribution. (05 Mar 2000) |
| spinal anaesthesia | A form of regional anaesthesia that involves the injection of an anaesthetic into the epidural space (in the spinal canal), at predetermined location along the spine, to produce anaesthesia in all body regions that are supplied by nerves that arise below the anatomic region of the block. Often used for obstetrical procedures. Origin: Gr. Aisthesis = sensation (27 Sep 1997) |
