A Randomized Comparison Between Interscalene and Supraclavicular Brachial Plexus Blocks For Arthroscopic Shoulder Surgery
In Brief
A clinical study evaluating Interscalene block and Supraclavicular block for Pain, Postoperative and 3 related conditions. Completed, enrolled 44 participants across 1 site.
Detailed Summary
Interscalene brachial plexus block constitutes the analgesic criterion standard for shoulder surgery. However it is associated with a high incidence of hemidiaphragmatic paralysis (HDP) that may not be tolerated by patients with chronic pulmonary disease. This randomized controlled trial will compare ultrasound-guided interscalene block (ISB) and supraclavicular block in patients undergoing arthroscopic shoulder surgery. The main outcome is static pain at 30 minutes after arrival in the post anesthesia care unit (PACU) as measured by a numerical rate scale (NRS) from 0 to 10. Our research hypothesis is that interscalene and supraclavicular blocks will result in equivalent postoperative analgesia at 30 minutes in the PACU. The equivalence margin is set at 2 points

Interventions
Ultrasound guided brachial plexus block injecting 20 mL of 0.5% levobupivacaine with 5 micrograms of epinephrine per mL in the interscalene groove, under the prevertebral fascia.
Ultrasound guided brachial plexus injecting 20 mL of 0.5% levobupivacaine with 5 micrograms of epinephrine per mL (3 mL in the "corner pocket" followed by 17 mL posterolateral to the brachial plexus).
