Overview
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.
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.
