Experimentální: SPENG Block
Participants assigned to this group will receive an ultrasound-guided Shoulder Posterior Pericapsular Nerve Group (SPENG) block before general anesthesia for shoulder arthroscopy.
A total of 20 mL of 0.25% bupivacaine with epinephrine 1:200,000 will be administered as a single injection between the posterior glenoid rim and the deep surface of the infraspinatus muscle.
|
An ultrasound-guided single-injection posterior pericapsular block.
With the participant in the lateral decubitus position and the operative shoulder uppermost, a high-frequency linear ultrasound transducer will be placed transversely immediately inferior to the posterior acromion.
After identification of the humeral head, articular cartilage, infraspinatus muscle, and posterior glenoid rim, a block needle will be advanced in-plane in a medial-to-lateral direction.
The needle tip will be positioned between the posterior glenoid rim and the deep surface of the infraspinatus muscle, and 20 mL of 0.25% bupivacaine with epinephrine 1:200,000 will be injected.

Aktivní komparátor: Posterior Suprascapular and Axillary Nerve Blocks
Participants assigned to this group will receive ultrasound-guided posterior suprascapular and axillary nerve blocks before general anesthesia for shoulder arthroscopy.
A total of 20 mL of 0.25% bupivacaine with epinephrine 1:200,000 will be administered, consisting of 10 mL for the posterior suprascapular nerve block and 10 mL for the axillary nerve block.

wo ultrasound-guided nerve blocks will be performed.
For the posterior suprascapular nerve block, the suprascapular nerve will be identified in the suprascapular notch region beneath the supraspinatus muscle, and 10 mL of 0.25% bupivacaine with epinephrine 1:200,000 will be administered.
For the axillary nerve block, the posterior humeral circumflex artery will be identified using color Doppler in the quadrilateral space, and 10 mL of 0.25% bupivacaine with epinephrine 1:200,000 will be administered adjacent to the axillary nerve.

Highest Resting Numeric Rating Scale Pain Score During the First 24 Postoperative Hours
Časové okno: From arrival in the post-anesthesia care unit through 24 hours after surgery
|
Resting postoperative pain intensity will be assessed using an 11-point Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain).
For each participant, the highest resting NRS score recorded during the first 24 postoperative hours will be used as the primary outcome.
Scheduled assessments will be performed on arrival in the post-anesthesia care unit and at 4, 8, 12, and 24 hours after surgery.
Resting NRS scores obtained immediately before rescue analgesic administration outside these scheduled assessments will also be included when determining the highest value.

Proportion of Participants With Complete Dual-Target Sensory Block Success
Časové okno: 30 minutes after block completion
|
Cold sensation will be assessed over the posterior shoulder (suprascapular nerve territory) and lateral deltoid region (axillary nerve territory) using a 3-point scale: 0 = absent sensation, 1 = reduced sensation, and 2 = normal sensation.
Suprascapular sensory component success will be defined as a reduction of at least one grade from baseline in the posterior shoulder region.
Axillary sensory component success will be defined as a reduction of at least one grade from baseline in the lateral deltoid region.
Complete dual-target sensory block success will require successful sensory blockade in both territories in the same participant.

|
Cumulative Opioid Consumption During the First 24 Postoperative Hours
Časové okno: From arrival in the post-anesthesia care unit through 24 hours after surgery
|
All rescue opioid analgesics administered during the first 24 postoperative hours will be recorded and converted to intravenous morphine-equivalent dose for comparison between groups.
|
From arrival in the post-anesthesia care unit through 24 hours after surgery
