The Effect of Pericapsular Nerve Group Block With Different Local Anesthetic Volumes

June 18, 2026 updated by: EMİNE ASLANLAR, Selcuk University

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Group I; PENG block, 20 mL 0.5% bupivacaine
Procedure: pericapsular nerve group (PENG) block
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.
Active Comparator: Group II; PENG block, 40ml 0.25% bupivacaine
Procedure: pericapsular nerve group (PENG) block
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.
