Ultrasound-guided saphenous nerve block – within versus distal to the adductor canal: a proof-of-principle randomized trial

Conclusion In this randomized trial, we found no differences in nerve visibility, block success rate, or onset between the AC and Peri-SBDGA techniques of ultrasound-guided saphenous nerve blockade, although the former technique provided superior vascular landmark visibility. Neither technique produced a sufficiently high success rate to provide reliable surgical anesthesia per se.
