Anesthesia and regional analgesia are considered tools that, since their first descriptions, have become an integral part of modern perioperative care. The history of regional and neuroaxial anesthesia has been characterized by the search for more effective and safe methods during surgical procedures. Based on the above, the advent of ultrasound in regional anesthesia allows performing procedures under 2D visualization of soft tissues, blood vessels and nerves, as well as bone references, always in real time, with the possibility of direct visualization of needle or punches, providing safety and increasing the success rate when visualizing the administration, behavior and distribution of the local anesthetic used. In recent years, new analgesic techniques, such as the use of interfascial or ultrasound-guided trunks, have been used as part of analgesic modalities during the perioperative period.
