Nerve Block Gallery - Infraclavicular Brachial Plexus Block Anatomy
Caption
This is an ultrasound clip demonstrating the anatomy for an infraclavicular block. The probe is placed in a parasagittal orientation just medial to the coracoid process and inferior to the clavicle. The axillary artery can be seen pulsating in the middle of the screen. The * denotes the three cords of the the brachial plexus at this location (lateral, medial, and posterior). Two muscles layers can be seen at the top of the screen, pec major and the underlying pec minor. Michael Macias
