anaesthesia

(ăn′ĭs-thē′zhə)
n.
Variant of anesthesia.

anaesthesia

anaesthesia

(1) Loss of pain sensation, as intentionally induced by drugs or medication.
(2) The loss of sensation. In medicine, this loss is “passive” (i.e., involuntary), as in crossed anaesthesia and tactile anaesthesia; in surgery, the loss of sensation is “active” (i.e., artificially-induced and controlled). Due in part to the potential for confusion, the alternate term, block, is widely preferred for local (surgical) anaesthesia; for systemic (e.g., general, intravenous) anaesthesia, confusion is less likely.
 
Some authors use the term analgesia in the same context as block, a practice which, as with anesthesia, may lend to confusion.

Complications
Nausea, vomiting, aspiration pneumonitis, renal failure, liver dysfunction.

an·es·the·si·a

(an'es-thē'zē-ă)
1. Loss of sensation resulting from pharmacologic depression of nerve function or from neurologic dysfunction; may be local, topical, general, or regional, depending on the affected area.
2. Broad term for anesthesiology as a clinical specialty.
Synonym(s): anaesthesia.
[G. anaisthēsia, fr. an- priv. + aisthēsis, sensation]

anaesthesia

Loss of the sensations of touch, pressure, pain or temperature in any part of, or in the whole of, the body. This may be due to injury or disease of nerves or brain, or to deliberate medical interference. Drugs are commonly used to effect either general or local anaesthesia.

anaesthesia 

1. A loss of sensation in a part, or in the whole body, induced by the administration of a drug (an anaesthetic agent).
2. A loss of sensation, usually touch, in a part of the body as a result of some nervous lesion. Example: corneal anaesthesia. Note: also spelt anesthesia. See peribulbar injection.
topical anaesthesia Application of a local anaesthetic agent to an area of the skin or mucous membrane (e.g. conjunctiva) to produce anaesthesia. The application may be via direct instillation, soaked swabs, ointments or sprays. Syn. surface anaesthesia.

an·es·the·si·a

(an'es-thē'zē-ă) Do not confuse this word with analgesia or hypesthesia.
1. Loss of sensation due to pharmacologic depression of nerve function or from neurogenic dysfunction.
2. Broad term for anesthesiology as a clinical specialty.
[G. anaisthēsia, fr. an- priv. + aisthēsis, sensation]
