Caudal anaesthesia (or caudal anesthesia) is a form of neuraxial regional anaesthesia conducted by accessing the epidural space via the sacral hiatus. It is typically used in paediatrics to provide peri- and post-operative analgesia for surgeries below the umbilicus. In adults, it can be used in the context of anorectal surgery or for chronic low back pain management.

It can be used as an alternative to general anaesthesia or as adjunct to it.
