What does anaesthetised mean?
Anaesthetised is the British past tense and past participle of anaesthetise, meaning to give someone an anaesthetic so that they lose consciousness or become insensitive to pain. It is also used adjectivally, as in “the anaesthetised patient,” to describe someone in that state. The word occurs especially in medicine, surgery, veterinary practice, and descriptions of medical procedures. Its use conveys a controlled, medically induced condition rather than ordinary tiredness or unconsciousness. Although the spelling is used in British English and other varieties influenced by it, American English normally uses anesthetized. Anaesthetised is therefore a precise term for describing both the action of administering an anaesthetic and the resulting condition of the person receiving it.
Describing someone who has been given an anaesthetic and is unconscious or insensitive to pain.
"The anaesthetised patient was monitored throughout the procedure."
Common in medical and veterinary contexts, and often used as a modifier of patient, animal, or body.
To administer an anaesthetic to someone, causing unconsciousness or insensitivity to pain.
"The surgeon anaesthetised the patient before making the first incision."
The past tense and past participle are the same form, anaesthetised.
Anaesthetised means more than simply sleepy: it describes a deliberately induced state in which pain is prevented and consciousness is temporarily lost.

Where does anaesthetised come from?
The word belongs to a family derived from Greek roots meaning “without” and “sensation” or “perception.” English anaesthetise developed in the 19th century in connection with the medical use of agents that made patients insensitive to pain, while anaesthetised is its regular past-tense and participle form.
