The purpose of this research is to determine if both local anesthetics are similar in their onset of sensory block to assess the efficiency of ultrasound-guided ankle blocks in our practice. Currently, standard of care is to perform ankles blocks with both mepivacaine and bupivacaine. However, given similarity in their safety profile, we would like to compare if one is non-inferior to the other in terms of onset time of ankle block.  

The objective of the study is to determine if there is a difference in ultrasound image quality of the interscalene block anatomy, at point of care, pre- versus post-operatively in a cohort of patients undergoing shoulder arthroscopy who routinely receive blockade of the brachial plexus for postoperative analgesia.
