The goal of this study is to compare the continuous brachial plexus block with or without intravenous patient controlled analgesia(PCA) in patients undergoing arthroscopic rotator cuff repair, in terms of quality of recovery, postoperative pain score, and adverse event.
The Bellomic® M silicone balloon infuser, dual continuous petite type (cebika, Uiwang-si, Gyeonggi-do, Republic of Korea) has 2-channel infusion elastomeric pump with two balloon chambers. This structure allows the simultaneous use of continuous nerve block and intravenous PCA. In addition, intravenous PCA can be continued even when continuous nerve block is discontinued due to discomfort such as numbness, tingling sense or motor block. This is expected to contribute to the patient satisfaction and quality of recovery.

Ultrasonography guided interscalene brachial plexus block was done with a 5 cm block needle and catheter was inserted. (Stimuplex®A, B Braun Medical, Bethlehem, PA). 10 mL 0.375 % ropivacaine was injected through the catheter. 0.2 % ropivacaine 4 ml/hour was injected through the continuous brachial plexus block catheter. IV-PCA with fentanyl (basal flow 0 ml with patient selected bolus 14 mcg, lockout 10 minutes) was started.
