Relationship between injectate volume and disposition in erector spinae plane block: a cadaveric study.

Increased ESP injection volumes resulted in more extensive cephalocaudal spread, resulting in anesthetic spread to the dorsal rami and ventral ES muscle without involvement of the ventral rami or other anterior structures. Injection volumes of 30 mL may be optimal for ESP blocks requiring analgesia across 4-7 levels.
