A trusted reference for ultrasound-guided regional anesthesia, used by anesthesiologists and pain specialists worldwide.
The app supports clinical preparation and learning across a wide range of regional anesthesia techniques. Covering nerve block procedures from head and neck to upper and lower extremities, thoracic, and abdominal wall blocks, it brings structured guidance and clear anatomy into one focused reference.
Commonly performed techniques such as TAP (Transversus Abdominis Plane) block, ESP (Erector Spinae Plane) block, Interscalene Brachial Plexus Block, and Popliteal Sciatic Nerve Block are presented alongside many other approaches, each with ultrasound-focused visuals, functional anatomy, and step-by-step preparation.
Designed for everyday use, the app combines sonoanatomy, patient positioning, and block-specific considerations to support confident decision-making before and during clinical practice.
Developed by NYSORA, a global educational organization dedicated to advancing regional anesthesia through structured, practice-focused education.
Reverse ultrasound anatomy = genius. It’s made identifying structures so much faster during scans.
