Brief Summary

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.

Conditions

Pericapsuler Nerve Group Block; Postoperative Pain

Keywords

arthroscopic shoulder surgery; postoperative pain; pericapsular nerve group block

Outcome Measures

Primary Outcomes (1)

• postoperative pain and opiod consumption

  postoperative 24 hours

Study Arms (2)

Group I; PENG block, 20 mL 0.5% bupivacaine

ACTIVE COMPARATOR

Procedure: pericapsular nerve group (PENG) block

Group II; PENG block, 40ml 0.25% bupivacaine

ACTIVE COMPARATOR

Procedure: pericapsular nerve group (PENG) block

Interventions

pericapsular nerve group (PENG) block PROCEDURE

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.

Group I; PENG block, 20 mL 0.5% bupivacaine; Group II; PENG block, 40ml 0.25% bupivacaine
