Anesthesia
Anesthesia or anaesthesia (see
spelling differences; from
Greek αν- an- “without” + αἲσθησις aisthesis “sensation”) has traditionally meant the condition of having the feeling of
pain and other
sensations blocked. This allows patients to undergo
surgery and other procedures without the distress and pain they would otherwise experience. The word was coined by
Oliver Wendell Holmes, Sr. in
1846. Another definition is a "reversible lack of awareness", whether this is a total lack of awareness (e.g. a general anaesthestic) or a lack of awareness of a part of a the body such as a spinal anaesthetic or another nerve block would cause.
