| circle absorption anaesthesia | Inhalation anaesthesia in which a circuit with carbon dioxide absorbent is used for complete (closed) or partial (saemiclosed) rebreathing of exhaled gases. (05 Mar 2000) |
|---|---|
| closed anaesthesia | Inhalation anaesthesia in which there is total rebreathing of all exhaled gases, except carbon dioxide which is absorbed; gas flow into the anaesthetic circuit consists only of oxygen, in amounts equal to the patient's metabolic consumption, plus small amounts of other gases (e.g., nitrous oxide) which undergo continued uptake by and distribution in the patient. (05 Mar 2000) |
| compression anaesthesia | Loss of sensation produced by pressure applied to a nerve. Synonym: compression anaesthesia. (05 Mar 2000) |
| conduction anaesthesia | Regional anaesthesia in which local anaesthetic solution is injected about nerves to inhibit nerve transmission; includes spinal, epidural, nerve block, and field block anaesthesia, but not local or topical anaesthesia. Synonym: block anaesthesia. (05 Mar 2000) |
| continuous 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) |
| crossed anaesthesia | Anaesthesia of one side of the head and the other side of the body due to a brainstem lesion. (05 Mar 2000) |
| presacral anaesthesia | Injection of local anaesthetic solution anterior to the sacrum, to block nerves as they exit from the sacral foramina. (05 Mar 2000) |
| pressure anaesthesia | Loss of sensation produced by pressure applied to a nerve. Synonym: compression anaesthesia. (05 Mar 2000) |
| sacral anaesthesia | Regional anaesthesia limited to those areas innervated by sacral sensory nerves. (05 Mar 2000) |
| 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) |
| 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) |
