Shoulder arthroscopy surgery is one of the most common orthopedic surgical procedures. Participants experience severe pain after shoulder arthroscopy surgery. This causes the use of high amounts of opioids, delays healing, causes bleeding in the surgical area, and can cause physiological disorders by increasing the stress response. Multiple studies have been conducted for analgesic purposes in shoulder surgery. Tran et al., posterior to the glenohumeral joint of the superior part of the suprascapular nerve, posterior inferior part of the posterior branch of the axillary nerve, anterior superior part of subscapularis superior branch, anterior claimed that the axillary nerve innervates the inferior part. In their case report, reported that the pericapsular nerve block (PENG) applied to participants undergoing shoulder surgery provided postoperative analgesia for 16-24 hours pericapsuler nerve block, which is generally applied in hip surgeries, can be applied in shoulder surgery, but there is no large-scale study on pericapsuler nerve block in shoulder surgery, and there is still unknown whether there is a relationship between the pericapsuler nerve block to be applied and the quality of postoperative recovery. Recovery after surgery and anesthesia is complex.

Shoulder arthroscopy surgery is one of the most common orthopedic surgical procedures. Participants experience severe pain after shoulder arthroscopy surgery. This causes the use of high amounts of opioids, delays healing, causes bleeding in the surgical area, and can cause physiological disorders by increasing the stress response. Multiple studies have been conducted for analgesic purposes in shoulder surgery. The axillary nerve is said to supply nerves to the inferior part of the suprascapular nerve, the posterior inferior part of the posterior branch of the axillary nerve, and the anterior superior part of the subscapularis superior branch. The study was done posterior to the glenohumeral joint. In their case report reported that the pericapsular nerve block (PENG) applied to participants undergoing shoulder surgery provided postoperative analgesia for 16-24 hours. The block, which is generally applied in hip surgeries, can be applied in shoulder surgery, but there is no large-scale study on the pericapsuler nerve block in shoulder surgery, and still unknown whether there is a relationship between the pericapsuler nerve block applied and the quality of postoperative recovery. Recovery after surgery and anesthesia is complex.

Application of the pericapsuler nerve block will provide better postoperative recovery and recovery scores in participants who will undergo shoulder arthroscopy surgery. The primary aim of this study is to evaluate the effectiveness of pericapsuler nerve block on postoperative recovery and recovery quality after shoulder arthroscopy surgery using the quality of recovery-15 questionnaire.

The secondery aim this study is to postoperatively immobilize and move numeric rating scale in participants undergoing shoulder arthroscopy surgery in which pericapsuler nerve block will be applied, the number of participants needing first-rescue analgesia, the time to first-rescue analgesia, and postoperative To evaluate complications, the number of patients in need of antiemetics, and patient satisfaction.
