Continuous Ultrasound-Guided Sacral Intervertebral Block for Postoperative Analgesia in Neonates.

Abstract

Any mass covering the sacral hiatus or partial sacrum agenesis would make a conventional caudal approach difficult. We describe two cases, a neonate with sacrococcygeal teratoma and another with caudal regression syndrome (CRS). An ultrasound-guided sacral intervertebral block with catheter placement was chosen as the technique to provide adequate postoperative analgesia.
