CCLS-ICBComparative Study on Hemidiaphragmatic Function: Costoclavicular vs. Lateral Sagittal Infraclavicular Block

This study focuses on comparing two different ultrasound-guided techniques for infraclavicular brachial plexus block, which are used to numb the arm for forearm, wrist, or hand surgery. The techniques are called costoclavicular and lateral sagittal approaches. The study is particularly interested in how these techniques affect the movement of half of the diaphragm, a muscle that helps us breathe. Adults scheduled for elective forearm or hand surgery are invited to participate in this study, which aims to improve the safety and effectiveness of regional anesthesia for upper extremity surgery. Participants in this study will receive either a costoclavicular or a lateral sagittal infraclavicular nerve block using a medication called bupivacaine, under ultrasound guidance. The study measures the movement of the diaphragm during normal and deep breathing using ultrasound to assess the effect of these block techniques. Other aspects evaluated include sensory and motor block characteristics, pain scores after surgery, pain medication requirements, and potential complications related to the block. The results of this study will help guide anesthesiologists in choosing the most appropriate technique for upper extremity surgery.
