About this trial
This study is a prospective, randomized, double-blind trial comparing patients who underwent arthroscopic rotator cuff repair and received an interscalene brachial plexus block (9 ml of 0.75% ropivacaine, 3 ml for each trunk) combined with suprascapular nerve block and axillary nerve block (each with 10 ml of 0.75% ropivacaine) versus those who received an interscalene brachial plexus block (9 ml of 0.75% ropivacaine, 3 ml for each trunk) combined with placebo suprascapular and axillary nerve blocks (each with 10 ml of 0.9% saline).
The study will compare subjective pain scores (VAS score) and patient satisfaction preoperatively and at 1, 3, 6, 12, 18, 24, 36, and 48 hours postoperatively. Additionally, 5 ml of venous blood will be collected preoperatively and at 1, 6, 12, 24, and 48 hours postoperatively to analyze and compare serum levels of cortisol, IL-6, IL-8, IL-1β, substance P, serotonin, β-endorphin, and norepinephrine.
