The Minimum Effective Concentration (MEC95) of different volumes of ropivacaine for ultrasound-guided caudal epidural block: a dose-finding study
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 . CEB may be beneficial in anorectal surgery because its use may extend postoperative analgesia, which reduce the need for systemic analgesics and their potential side effects [2, 3]. Although CEB has many clinical applications, it is sometimes difficult to ascertain the anatomical location of the sacral hiatus and the caudal epidural space, particularly in adults [4, 5].
