There are three types of anesthesia; local, regional, and general. Local anesthesia is specific; a small area of the body is numbed while one is conscious or awake. Regional anesthesia is administered to numb a specific region of nerves in the body. The patient may be awake/ conscious or receive a sedative for light sleep during the operation. The patient may remember parts of the procedure but should be free of pain. General anesthesia is a state of regulated unconsciousness that results in a loss of body sensation through anesthetic drugs, such as gases or vapors inhaled through a mask or breathing tube or drugs given through an IV. It is rare for patients to have any memory during general anesthesia. Get a consultation from an anesthesia hospital in Bangalore.
