About this study
Official title: The Effect of Pericapsular Nerve Group Block With Different Local Anesthetic Volumes on Postoperative Pain in Arthroscopic Shoulder Surgery
Early postoperative pain following shoulder surgery is a significant clinical problem for both patients and orthopedic surgeons. Effective pain control is crucial for improving postoperative comfort and optimizing rehabilitation. Pericapsular nerve group block (PENG) is a regional anesthesia method that has recently gained attention due to its lack of motor block and absence of pulmonary complications. The aim of this study is to evaluate the effect of PENG block, applied at two different volumes, on postoperative pain and opioid consumption in patients undergoing arthroscopic shoulder surgery.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
pericapsular nerve group (PENG) blockProcedure or surgery
During PENG block application; the patient's arm was rotated externally and abducted at 45 degrees. A longitudinal linear ultrasound probe was placed between the coracoid and humeral head. After identifying the humeral head, the tendon of the subscapular muscle, and the deltoid muscle above it, a 50 mm needle was inserted using the "in-plane" technique. After the needle tip was placed above the bone below the subscapularis tendon, a local anesthetic solution was injected.

What does the primary outcome measure?
postoperative pain and opiod consumption (time frame: postoperative 24 hours). It is what the study was designed to measure, not a finding.
