Our current standard of care is to perform an interscalene peripheral nerve block for patients receiving rotator cuff repair surgery as it is an effective opioid-free alternative for post-operative pain control. However, many of these repairs require a supplemental incision for an open biceps tenodesis, which is not covered by the interscalene block. The intercostobrachial nerve covers this incision and is targeted by an axillary ring block or a single shot nerve block in the fascial plane between the pectoralis minor and serratus anterior muscles (otherwise termed as a PECS II block). This study will attempt to delineate if one is superior in postoperative analgesia and mitigating intraoperative stimulation by comparing an axillary ring block to a PECS II block. Patients receiving a rotator cuff repair with biceps tenodesis without histories of chronic opioid use and respiratory compromise will be eligible to be enrolled in the study. All patients will receive an interscalene block and group 1 will receive a supplemental axillary ring block and group 2 will instead receive a PECS II block. After surgery, the patients' pain score will be assessed upon PACU arrival, at 6 hours after block, and 2 weeks postoperatively. Their opioid requirements will also be assessed. Our primary outcome is pain score at 6 hours following the block.
