The difference between local anesthesia and general anesthesia is as follows: 1. Local anesthesia Local anesthesia is mainly used for smaller superficial surgical operations, or when operations are performed in localized areas. In the process of local anesthesia, the person is conscious, and usually, due to the current level of anesthesia technology, a large number of local anesthesia, such as local infiltration anesthesia, surface anesthesia, regional block anesthesia, and intravertebral anesthesia, have been gradually carried out. 2. General anesthesia requires the body to be unconscious by inhalation or intravenous form. General anesthesia is used for certain major surgeries, such as liver transplants, heart transplants, and intra-abdominal surgeries. General anesthesia includes inhalation or intravenous administration of general anesthesia. When the surgery is over, the patient is given a general anesthetic to wake him or her up as the surgery ends.
