An anesthetic is any one of a diverse group of compounds used to prevent sensation and awareness. Anesthetics act in a number of ways, including pain prevention, memory loss and muscle relaxation. WebMD: Anesthesia - Topic Overview Drugs.com: Types Of Anesthesia

1. Local anesthetics numb only a small specific area of the body and are used for minor procedures. The patient is able to remain awake.
2. Regional anesthetics block pain impulses along the spinal cord (spinal anesthesia) or along a group of nerves (nerve block).
3. General anesthetics act directly on the brain. The patient remains completely unconscious, does not feel pain and is unaware of stimulation while under general anesthesia. General anesthetics can be given intravenously or by inhalation.WebMD: Anesthesia - Topic Overview WebMD Anesthesia - Types of Anesthesia HealthAtoZ: Anesthesia, Local Anesthesiology Info: How Does Anesthesia Work?
