Anesthesia is a medical state in which you lose feeling, and sometimes consciousness, so you do not feel pain during surgery or other procedures. It can affect just one area of the body or the whole body.
From Greek 'an-' meaning 'without' and 'aísthēsis' meaning 'sensation' or 'feeling'. The modern medical use grew in the 19th century with the discovery of drugs that could safely block pain.
