Lateral Sagittal vs Costoclavicular Approach for Ultrasound-Guided Infraclavicular Block

The US probe will be located medial to the coracoid process in the sagittal plane in the infraclavicular region, and then three cords of the brachial plexus will be viewed. Using the in-plane technique, bupivacaine 0.5% will be administered around the posterior cord (7ml), lateral cord (7ml), and medial cord (6ml).

The US probe will be placed parallel to the clavicle in the midclavicular area and tilted toward the cephalad and the axillary artery, and three cords will be viewed. A needle will be forwarded from lateral to medial with the in-plane technique, and 20 ml of bupivacaine 0.5% will be administered at the center of the three cords.
