    Area of Science:

    • Anesthesiology
    • Regional Anesthesia
    • Orthopedic Surgery

    Context:

    • General anesthesia is standard for shoulder surgery.
    • Alternative anesthetic techniques are being explored for total shoulder arthroplasty.
    • Interscalene block is a regional anesthesia technique for the shoulder.

    Purpose:

    • To evaluate the feasibility of using a guided interscalene block as the sole anesthetic technique for total shoulder arthroplasty.
    • To assess intraoperative and postoperative outcomes, including analgesia, motor block, success rate, and patient satisfaction.

    Summary:

    • A neurostimulation-guided interscalene block combined with dexmedetomidine sedation was used in 100% of patients undergoing total shoulder arthroplasty.
    • Intraoperative analgesia was achieved in all patients, with minimal motor block. Postoperative pain scores were low at 6, 12, and 24 hours.

  • The technique demonstrated a 100% success rate, with 100% patient satisfaction and a low complication rate of 8.18%.

    • Impact:

    • This study demonstrates that guided interscalene block with sedation is a safe and effective alternative to general anesthesia for total shoulder arthroplasty.
    • The findings support the use of this technique, potentially improving patient outcomes and recovery.
    • This approach offers a viable option for patients seeking single-anesthetic techniques for shoulder replacement surgery.
