It is generally accepted that anesthesia is a reversible functional inhibition of the central and/or peripheral nervous system, produced by drugs or other means, and this inhibition is characterized primarily by loss of sensation, particularly pain. Anesthesia, as the name suggests, is numbness paralysis, and drunkenness is coma. Therefore, anesthesia means that a patient temporarily loses his or her feeling wholly or locally by medication or other means to perform surgical treatment for the purpose of painlessness. The anesthesia is divided into epidural anesthesia, which refers to epidural space block anesthesia, i.e., local anesthetic is injected into an epidural space to block spinal nerve root, so that the innervation area is paralyzed temporarily, and the anesthesia is called epidural space block anesthesia, or epidural space block for short. Depending on the mode of administration, a single-dose method and a continuous method can be classified. The puncture position can be divided into high position, middle position, low position and sacral canal block.
