Axillary Nerve Block Combined With Suprascapular Nerve Block

Purpose: The purpose of this study is to compare the result of combined sono-guided suprascapular nerve block (SSNB) and axillary nerve block (ANB) with isolated SSNB in postoperative pain following arthroscopic rotator cuff repair. Our hypothesis was that SSNB combined ANB would show a more effective anesthesia for arthroscopic rotator cuff repair as compared with SSNB only. Methods: Forty-two patients with rotator cuff tear who had undergone arthroscopic rotator cuff repair were enrolled in this study. Among them, 21 patients were randomly allocated into group I, and received SSNB and ANB with each 10mL ropivacaine. The other 21 patients were allocated into group II, and received SSNB with 10mL ropivacaine and ANB with 10mL normal saline. Visual Analogue Scale (VAS) pain score, patient's satisfaction (SAT), and Lateral Pain Index (LPI), etc was checked at postoperative 1, 3, 6, 12, 18, 24, 36, and 48 hours.
