Caudal Epidural Block

Brief summary

Caudal epidural block is the most commonly used technique for analgesia in pediatric patients. Although there are clinically used doses of local anesthetics for caudal epidural block, we do not know exactly how much levels are blocked in young children. Thus, we aimed to identify the spreading of injection of local anesthetics for caudal epidural block using ultrasound imaging in young children.
