Effectiveness of Field Block Compared With Interscalene Block in Shoulder Surgery

This study will compare two different types of anesthesia used for shoulder surgery. The first method, called an interscalene block, is commonly performed by anesthesiologists and is effective for pain control but may cause side effects such as breathing problems, arm weakness, or discomfort. The second method, called a shoulder field block, is a newer technique performed by orthopedic surgeons that numbs the nerves around the shoulder without affecting breathing. Patients scheduled for shoulder surgery will be randomly assigned to receive either the interscalene block or the shoulder field block. The main goal of the study is to find out whether the shoulder field block provides pain relief that is as effective as the interscalene block, but with fewer side effects. Pain levels, patient satisfaction, length of hospital stay, need for pain medication, and any complications will be recorded and compared between the two groups. The results may help identify a safe and effective alternative anesthesia option for patients undergoing shoulder surgery.
