Comparison of Ultrasound-guided Interscalene, Erector Spinae Plane, Costoclavicular, and Supraclavicular Blocks on Breathing Muscle Paralysis, Recovery Quality, Opioid Use, and Pain in Arthroscopic Shoulder Surgery

What this Trial Is About

Researchers are evaluating the effects of four different ultrasound-guided regional anesthesia techniques— the interscalene, erector spinae plane, costoclavicular, and supraclavicular blocks—on patients undergoing arthroscopic shoulder surgery. This study aims to understand how these blocks influence hemidiaphragmatic paralysis, the quality of postoperative recovery, opioid use, and pain levels after surgery. Arthroscopic shoulder surgery, used to treat various shoulder conditions, often causes moderate to severe pain that can affect recovery, making effective pain management important. Before surgery, participants will receive one of four ultrasound-guided nerve blocks: interscalene, erector spinae plane, costoclavicular, or supraclavicular. Each block is performed under standard anesthesia monitoring to provide pain relief during and after the procedure. The study observes how each block affects breathing muscle function, recovery quality, opioid consumption, and pain scores. Participants will be monitored closely with assessments including evaluation of hemidiaphragmatic paralysis 30 minutes after the block, recovery quality 5 minutes post-block, and measurement of opioid use and pain intensity over 24 hours after surgery. These outcomes will help determine how each anesthesia technique impacts patient comfort and recovery. The total participation involves the surgery day and immediate postoperative period with detailed monitoring of pain and respiratory function.
