Infraclavicular Block

After identification of this landmark, a point is marked 2 cm medial and 2 cm caudad to the most anterior tip of the coracoid process.

A. View of right shoulder demonstrating surface anatomy relevant to the infraclavicular block. CP, coracoid process of the scapula; C, clavicle. B. A small curvilinear transducer is placed medial and caudad to the coracoid process with the arm abducted 90 degrees to optimize the crosssectional imaging of the neurovascular bundle. The block needle is inserted cephalad to the transducer and directed caudad for in-plane needle guidance.

Approach and Technique

With a small curvilinear (preferred) or linear transducer positioned medial and caudad to the coracoid process and oriented vertically, the brachial plexus cords are visualized in shortaxis surrounding the axillary artery.
