regional anesthesia resulting from injection of an anesthetic into the caudal end of the spinal canal; now largely replaced by epidural anesthesia

[RobertFaw]

A caudal block is a type of regional anesthesia or analgesia that involves injecting medication into the caudal epidural space in the lower spine, typically via the sacral hiatus. This method primarily blocks sensation to the lower part of the body, and is often used for pain management during surgeries or procedures involving the lower abdomen, pelvis, or lower extremities.
