Overview
Brief Summary
Shoulder arthroplasty is associated with significant postoperative pain. Appropriate pain control after shoulder arthroplasty is crucial for postoperative rehabilitation and patient satisfaction. Superior trunk block is a commonly employed regional anesthetic technique for shouler arthroplasty, and a continuous catheter is often placed to extend the analgesic benefit of the block. However, continuous peripheral nervel block (PNB) is more costly and time-consuming than sigle-shot PNB. Recent evidence suggests that intravenous (IV) dexmedetomidine (DEX) prolong the analgesic duration after sigle-shot PNB. The investigators will compare continuous superior trunk block with single-shot superior trunk block with IV DEX in patients undergoing shoulder arthroplasty.

Outcomes
Primary Outcomes
Numeric rating scale pain score
Time Frame: 24 hours after the end of surgery
Pain intensity at rest will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) 24 hours after the surgery.
