Anaesthesia is given to patients so that surgery and other medical procedures can be carried out safely and without pain. The word anaesthesia means ‘loss of sensation’. People under anaesthesia will ‘lose’ feelings of pain and other sensations.
It can be relatively simple, like numbing an area around a tooth during dental treatment, or something more complex, like using powerful drugs to cause unconsciousness.
An Anaesthetist administers your anaesthesia.
