NCT04930393

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Score at 6 hours following the block

    6 hours post-block

Secondary Outcomes (2)

  • Morphine milligram equivalents (MME)

    Right after surgery and 2 weeks

  • Intraoperative Stimulation

    2 hours during surgery

Study Arms (2)

PECS II Block

ACTIVE COMPARATOR

This group will receive an interscalene block in addition to a pectoral nerve block under ultrasound guidance with local anesthetic injected in the plane between the pectoralis minor and serratus anterior muscles

Procedure: Nerve Block - either PECS II or axillary ring

Axillary Ring Block

ACTIVE COMPARATOR

This group will receive an interscalene block in addition to a ring block with local anesthetic injected subcutaneously along the axilla from anterior to posterior direction.

Procedure: Nerve Block - either PECS II or axillary ring

Interventions

In addition to an interscalene nerve block, one of these two interventions will be administered to assess pain control after a biceps tenodesis

Axillary Ring BlockPECS II Block
