Summary
Total shoulder arthroplasty (TSA) is considered to be a major surgical procedure resulting in
severe postoperative pain, especially in the first 48 hours after surgery. The use of
interscalene brachial plexus nerve block remains the cornerstone for analgesia following
shoulder surgery; however, with the advent of local infiltration analgesia (LIA), there has
been increasing interest in its use for total joint arthroplasty.
Since the benefits of local infiltration analgesia within a comprehensive multi-modal
analgesia clinical pathway have yet to be established for total shoulder arthroplasty, the
Investigators plan to assess and compare analgesia outcomes between three intervention
groups: single shot interscalene brachial plexus block (SISB), continuous interscalene
brachial plexus block (CISB), and local infiltration analgesia (LIA).
