Summary

This study aims to evaluate the diaphragmatic movement and postoperative analgesia following anterior glenoid, suprascapular, and interscalene nerve blocks in patients undergoing elective arthroscopic shoulder surgery.

Detailed description

Arthroscopic shoulder surgery is a key approach for diagnosing and treating many shoulder disorders. Nevertheless, 30-70% of patients often experience moderate to severe pain, especially at 48 h after the operation, which affects rapid recovery. The interscalene brachial plexus block (ISB) remains the gold standard for providing analgesia after shoulder surgery. Suprascapular nerve block (SSNB) is the most commonly used regional nerve block. Seventy percent of the sensory nerve fibers of the shoulder joint are innervated by the suprascapular nerve (SSN), with the supraspinatus and infraspinatus being directly innervated by the SSN.

Conditions

• Interscalene Block
• Suprascapular Nerve Block
• Anterior Glenoid Nerve Block
• Diaphragmatic Excursion
• Analgesia
• Arthroscopic Shoulder Surgery

Interventions

Type	Name	Description
OTHER	Interscalene brachial plexus block	Patients will receive general anesthesia, plus an ultrasound-guided interscalene brachial plexus block (ISB) with the injection of 15 mL of 0.25% bupivacaine.
OTHER	Suprascapular nerve block	Patients will receive general anesthesia plus an ultrasound-guided suprascapular nerve block (SSNB) with injection of 15 ml of 0.25% bupivacaine.
OTHER	Anterior glenoid block	Patients will receive general anesthesia plus an ultrasound-guided anterior glenoid block with injection of 15 ml of 0.25% bupivacaine.
OTHER	Suprascapular nerve block + Anterior glenoid block	Patients will receive general anesthesia, along with a total volume of 30 mL of 0.25% bupivacaine, divided into 15 mL for ultrasound-guided SSNB and 15 mL for ultrasound-guided anterior glenoid block.
