About this app

AnSo is a convenient resource designed to help anaesthetists identify common sonoanatomy, in a time efficient manner, within the busy operating theatre. It has been created by practicing anaesthetists with an interest in teaching ultrasound and regional anaesthesia.
AnSo helps identify not only the target structures but all the surrounding sonoanatomy. This more comprehensive understanding of the sonoanatomy helps detect anatomical variability, improves the safety and efficacy of procedures, and facilitates learning and teaching.

AnSo also:
- 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

AnSo has been designed in a format that can be easily updated and distributed to users so the information can be kept as current as possible in this rapidly expanding field.


AnSo contains:
- over 250 ultrasound images with over 1500 sonoanatomy colour overlays,
- innervation images,
- ergonomic images,
- landmarks pattern sketches,
- loops when required for dynamic sonoanatomy,
- notes with tips from experienced clinicians.

AnSo does not require an internet connection to run. Once downloaded all data is stored on your device so it will work anywhere and images will display without any delay. It can be useful both in and out of theatre, when performing procedures, and when learning or teaching ultrasound. There is no advertising on the app.

Ratings and reviews

I purchased the app and it was OK for what it was. All of a sudden, just recently, the app does not want to open unless I "subscribe" for extra money. This is a bait and switch as I paid for it once and now I can't use it. I subscribed and already a whole day later it does not open stating "loading images - it can take a while". Very disappointed with it. I am going to drop the subscription and delete it from my device.

Well..... Switched phone and had to re-download and low and behold...... Even though I paid for it before, it's not a paid subscription. Very disappointing to those of us who did the one time purchase before. This is my favorite regional app and I've recommended it to everyone because it was only a one time payment...

Used this app in residency - worked great. They switched to a subscription model (instead of one time purchase). Now when I pay for the subscription, it's perpetually "Loading Data" and doesn't let you see any sono-anatomy/block locations. Clearing app data worked
