Benefits of Ultrasound Imaging for Placement of Caudal Epidural Blockade in 3 Pediatric Patients: A Case Report.

Pediatric caudal epidural blockade, the most common pediatric regional anesthetic, is classically placed using surface landmark technique with infrequent use of ultrasound guidance. We present 3 cases where ultrasound guidance facilitated successful placement and helped prevent complications. One infant had an unanticipated S5 dural sac necessitating needle redirection to avoid subarachnoid injection. A 5-year old had proper needle position with inability to inject secondary to needle blockage confirmed with ultrasound. An expremature infant had initial needle placement anterior to the sacrum with subsequent proper placement using real-time ultrasound imaging. Ultrasound guidance for pediatric caudal placement confers advantages and increased routine use should be considered.
