About

This study aims to compare the serratus posterior superior intercostal plane block and suprascapular nerve block and axillary nerve block for analgesia in shoulder arthroscopic surgery.

Full description

Controlling postoperative pain while minimizing opioid administration is particularly important because poor pain control is thought to be responsible for more than 60% of unplanned or prolonged hospitalizations.

Suprascapular nerve block (SSNB) has been proposed based on the anatomic fact that the suprascapular nerve innervates approximately 70% of the shoulder joint, capsule, subacromial space, acromioclavicular joint, and coracoacromial ligament, with the remaining 30% thought to be innervated by the lateral pectoral and axillary nerve.

The combined SSNB and axillary nerve block (ANB) was proposed as a safe alternative to interscalene brachial plexus block (ISB) for providing anesthesia and postoperative analgesia for shoulder surgery.

Serratus posterior superior intercostal plane block (SPSIPB) was described as a novel technique in a case series study of cadavers and five patients.
