What is subdural anesthesia

Commonly used is epidural anesthesia. You can choose any intervertebral space for epidural puncture, not the lumbar spine 2-3 space mentioned upstairs. After a bolus injection of anesthetics, anesthesia of a certain spinal cord segment is produced.

Subdural anesthesia is an accident during epidural anesthesia, that is, the drug solution enters the subdural space instead of the epidural, but does not enter the cerebrospinal fluid. An abnormally wide block may occur, which may also cause danger. . Of course this rarely happens.
