Overview
Brief Summary
The investigators will evaluate the influence of intraoperative remifentanil infusion on the postoperative hyperalgesia in patients receiving rotator cuff repair after brachial plexus block for postoperative analgesia.
Detailed Description
The study will include 68 patients undergoing rotator cuff repair. All patients will receive brachial plexus block for postoperative analgesia, followed by general anesthesia. In the experimental group, remifentanil infusion will not be used intraoperatively, and in the control group, remifentanil will be infused. After surgery, both groups will be given the same postoperative pain management using patient controlled analgesia(PCA), and pain patterns will be assessed using the Numerical rating scale (NRS) at 4 hour intervals for 24 hours. The primary end point of this study is the total dose of PCA medication over 24 hours.
