Ultrasound-Guided Supraclavicular Brachial Plexus Nerve Block

Abstract The supraclavicular brachial plexus (BP) block, initially introduced in the early twentieth century, remains one of the most effective and widely adopted regional anesthesia techniques for upper limb procedures. Its compact anatomical layout and proximity to surface landmarks render it particularly suitable for ultrasound-guided applications. This review provides a detailed account of the technique, comparative anatomy of alternative BP blocks, indications, contraindications, anatomical considerations, procedural steps, ultrasound landmarks, complications, and benefits of the supraclavicular block in clinical practice.
