TAP vs Caudal Block Using Dexmedetomidine/ Bupivacaine for Post Operative Analgesia

Caudal epidural block is a well-established and commonly performed regional neuraxial technique for providing intraoperative and postoperative analgesia in children scheduled for lower abdomen/perineal surgical interventions. Although the efficacy and safety of Caudal epidural block are fairly high, the associated complications, such as inadvertent dural puncture, unwarranted motor blockade of the lower limbs, and disturbance of bladder function, limit its use. Furthermore, a major limitation of an uncomplicated Caudal epidural block when administered as a "single-shot" technique is its brief duration of action (up to 6 hours), which makes administration of additional analgesics necessary .
