Summary

Cervical paravertebral blocks (CPVBs) target the brachial plexus from a puncture site situated in the posterior aspect of the neck and represent an alternative to interscalene blocks (ISBs) for shoulder and proximal humeral surgery. Randomized controlled trials comparing CPVB and ISB have found no significant differences in success rate, onset and offset times. Because of the reliability of their cutaneous landmarks, CPVBs have become part of the investigators' standard practice. With this approach, the brachial approach can be identified either with loss of resistance to air (LOR) or nerve stimulation (NS). While some authors have used only LOR and reported good success rates, others have hypothesized that NS may increase the reliability of the block. In the proposed study, for the first time, the 2 methods will be formally compared.
