Lateral Sagittal vs Costoclavicular Approach for Ultrasound-Guided Infraclavicular Block

The CC approach is a recently introduced infraclavicular approach that targets three cords (medial, lateral and posterior) located lateral to the axillary artery in the costoclavicular space. Cords in this space are located more superficially than with the classical approach at the lateral infraclavicular fossa and are clustered but maintain a consistent anatomical relationship with each other. Patients will be divided into two groups: Group LS: Ultrasound-guided infraclavicular block - lateral sagittal approach (20 ml 0.5% bupivacaine) Group CC: Ultrasound-guided infraclavicular block - costoclavicular approach (20 ml 0.5% bupivacaine)
