Anesthesia is a drug that numbs part of your body or makes you unconscious so that you don't experience pain during a procedure like surgery. It is done in general practice to avoid pain during surgery. It is of two type general anesthesia and local anesthesia depending on the site of surgery.
Anesthesia is classified into three broad categories General anesthesia, Sedation, Conduction anesthesia,. The anesthesia that suppresses central nervous system activity and results in unconsciousness and total lack of sensation is general. Sedation also calleddissociative anesthesia) inhibits transmission of nerve impulses between the cerebral cortex and limbic system. Conduction commonly known as regional or local anesthesia, which causes loss of sensation in the targeted body part by blocking transmission of nerve impulses between a targeted part of the body and the spinal cord.
