Caudal block is a common regional anesthesia technique in pediatrics with landmark method predominantly being practiced. Ultrasound-guided technique provides real-time visualization of the structures and injection while performing caudal block.

We performed this meta-analysis to determine the utility of ultrasound in caudal blocks in children over the landmark-based technique.

Randomized controlled trials comparing ultrasound-guided caudal blocks and landmark technique in pediatrics were searched from databases—PubMed, Embase, Scopus, and CENTRAL from inception until August 2020.

The primary objective was success rate between the two techniques and secondary objectives included time to perform the block, first puncture success, and complications.
