Clinical trials

This study aims to compare two commonly used regional anesthesia techniques for shoulder arthroscopy: the ultrasound-guided interscalene block and the combined interscalene-suprascapular nerve block. Both techniques are routinely performed to reduce pain during and after shoulder surgery. The purpose of this study is to determine which method provides better postoperative pain control, reduces the need for pain medication, and causes fewer side effects such as diaphragmatic dysfunction. Participants will receive one of the two nerve block techniques before surgery, and their pain scores, opioid consumption, and respiratory effects will be monitored during the first 24 hours after the operation.
