Caudal epidural block (CEB) is a kind of epidural anesthesia in which local anesthesia is injected through the sacral hiatus into the sacral epidural space to block the sacral nerve and temporarily paralyze the area it controls [Ultrasonography has been reported to be beneficial in administering regional anesthesia. This technique is useful for visualizing the sacral hiatus and sacrococcygeal ligament, inserting the needle, and distributing the local anesthetic agent. Klocke and colleagues described ultrasound-guided CEB in 2003, and it has become increasingly popular [In clinical, minor anorectal surgeries are often performed in day care facilities, using spinal anesthesia modified into a saddle block. However, CEB offers certain advantages. such as minimal motor blockade, early mobilization, lesser degree of hypotension, and lesser chances of postoperative puncture headache. Other potential advantages of the caudal route include ease of positioning and selective blocking of sacral nerves. Ultrasound-guided CEB can be considered as an option for anorectal procedures of short duration with acceptable success rates, surgical conditions, and patient comfort. [
