Ultrasound-guided peripheral nerve blocks can be used as the primary anesthetic for surgery involving the extremities and trunk and as a modality for opioid-sparing postoperative pain management. Success of regional anesthesia is dependent upon depositing local anesthetics in the correct plane. Advent of ultrasound has made this process more efficient, safer, and less painful for the patient More prevalent use of regional anesthesia in the perioperative setting will limit opioid prescription, development of chronic post surgical pain and is known to improve patient satisfaction by improving pain. This chapter reviews the history of ultrasound use for nerve blocks and basics of ultrasound use. It also discusses common peripheral nerve blocks of the upper extremities, trunk area, and lower extremities and summarizes indications, techniques, and key complications. Included are ultrasound images for each block.
