No results posted yet for this study

Summary

The purpose of this study is to determine whether the combination of suprascapular and axillary nerve blocks is non-inferior to the conventional interscalene block (ISB) in providing pain relief during the first postoperative day to adult healthy patients (age \> 18) undergoing ambulatory shoulder surgery.

Conditions

  • Shoulder Pain

Interventions

DRUG

Suprascapular & axillary blocks

After infiltration with 1 mL of 1% lidocaine, local anesthetics (20 mL of 0.5% ropivacaine) will then be injected in 5 mL aliquots to achieve circumferential spread around the nerve.The axillary nerve block will be performed next in the posterior aspect of the operative arm. The neurovascular bundle encompassing the humeral artery, posterior circumflex artery, and axillary nerve is visualized in the lateral edge of the quadrangular space, deep to the deltoid muscle, inferior to the teres minor muscle, and superior to the triceps tendon. After infiltration with 1 mL of 1% lidocaine, local anesthetics (20 mL of 0.5% ropivacaine) will then be injected in 5 mL aliquots after negative aspiration to achieve circumferential spread around the bundle.

DRUG

Interscalene block

After sterile skin preparation with chlorhexidine and infiltration with 1 mL of 1% lidocaine, a 5 cm 22 G insulated needle is then inserted and local anesthetic solution (20 mL of 0.5% ropivacaine) will be injected in 5 mL aliquots after negative aspiration for blood to achieve spread posterior to or between the C5 and C6 nerve roots.
