The supraclavicular block is a regional anesthetic technique used as an alternative or adjunct to general anesthesia or used for postoperative pain control for upper extremity surgeries (mid-humerus through the hand). First introduced in 1911 by Kulenkampff as a landmark-based approach, the associated risk of pneumothorax was likely responsible for the technique falling out of favor. With the advent of ultrasonography, La Grange described the utilization of the Doppler probe to identify arteries in 1978. Contemporarily, Kapral and colleagues advocated for the dynamic use of ultrasound to guide needle advancement in the supraclavicular position. Colloquially known as the "spinal of the arm," the supraclavicular block is advantageous as the brachial plexus nerves are tightly packed in this approach and speed of onset is often rapidly achieved. However, because of this consolidated relationship, consider restricting volumes of local anesthesia to as low as possible to achieve goals, as compression ischemia may occur.
