Abstract：
Caudal epidural catheters provide exceptional analgesia while avoiding or minimizing opioids. Historically, the catheter tip location (dermatomal level) was estimated or verified via epidurogram. According to the Pediatric Regional Anesthesia Database, the majority of caudal-to-thoracic epidural catheters are placed without imaging guidance or verification of the position of the catheter tip. Ponde et al demonstrated that catheter insertion depth was longer when using ultrasound guidance than when estimated by external measurement. We report a simple yet novel ultrasound approach for catheter localization.
