Comparison of Interscalene and Pericapsular Nerve Group (PENG) Block in Shoulder Surgery

Visual Analogue Score

Early postoperative pain after shoulder surgery is a major concern and distress for patients and orthopedic surgeons. Adequate pain control; It is vital for all aspects of patient recovery, including mental state, nutrition, cost of care period, rehabilitation, patient satisfaction, and overall post-surgery outcomes.Single analgesic regimens are not always effective in controlling moderate to severe postoperative pain.Therefore, multimodal pain management is preferred and is currently recommended for early postoperative pain control.Regional anesthesia is preferred in shoulder surgery as an effective way to provide anesthesia and postoperative analgesia.To ensure adequate postoperative pain control, nerve supply to the synovium, capsule, joint surfaces, ligaments, periosteum and shoulder muscles must be blocked.Interscalene blocks are well studied and established means of providing analgesia following shoulder surgery and are considered the gold standard mode of regional anesthesia.Pericapsular nerve group block is a new block that provides a pericapsular distribution with local anesthetic infiltration around the glenohumeral joint and provides analgesia without motor blockage by reaching the sensory nerve branches of the glenohumeral joint.The aim of this study was to compare the results between interscalene block and pericapsular nerve group block in patients undergoing shoulder surgery.
