AnSo:
- provides multiple examples of the sonoanatomy as every individual is different,
- provides landmark sketches useful for developing pattern recognition of landmark structures, and for trainees to draw in exams,
- displays the cutaneous, motor, osseous and visceral innervation of the numerous nerve blocks and fascial plane blocks now available, facilitating appropriate block choice and knowledge of expected results,
- allows combining and comparing block innervation,
- allows images to be flipped to display both L and R sided orientation,
- demonstrates functional ergonomics with patient, ultrasound screen and proceduralist positioning essential for efficient practical performance,
- provides block notes with sonoanatomy tips and practical tips from experienced clinicians which can be invaluable to the learner.
AnSo is not only for regional anaesthesia but includes many other perioperative uses of ultrasound relevant to the anaesthetist, such as:
- airway
- gastric antrum
- vascular access
- spine
- transthoracic echo
- lung signs
