give introduction to anaesthesia?

Answer 1

Anesthesia or anaesthesia (see spelling differences), has traditionally meant the process of blocking the perception of pain and other sensations. This allows patients to undergo surgery and other procedures without the distress and pain they would otherwise experience. It comes from the Greek roots an-, "not, without" and aesthētos, "perceptible, able to feel". The word was coined by Oliver Wendell Holmes, Sr. in 1846.

Today, the term anesthesia in it's most general form has 5 components 1. Analgesia - blocking the conscious perception of pain 2. Hypnosis - producing unconsciousness 3. Amnesia - preventing memory formation 4. Relaxation - preventing unwanted movement or muscle tone 5. Homeostasis - preserving normal body functioning (e.g., maintaining blood pressure within normal physiologic range)
