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.
Download AnSo today and always have access to this sonoanatomy and nerve block resource.

Ratings and reviews

Surprise update that changes app to subscription. Paid for the app in full. At least grandfather your early supporters. (5/13/22) Please forward link to pre-subscription apk. I do not wish to move forward with new pay structure. Also, contrary to your statement, 1 free year is not provided. The app insist on payment or no fuctionality (5/16/22) Still no way to receive the free year. It only provides the option for free trial then payment. I just want a version prior to the subscription model.

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.

To echo some of the preceding reviews, after agreeing to a one time pay, I get the surprise of having to commit to a subscription, something I never agreed to when I initially paid for this app! Additionally, it was interesting to learn that my coworker, an apple user, did not have to experience this clear bait & switch! I have no interest in any new updates that come with paying additional costs. I would like to have access to the original app for which I paid for under the agreed provisions!
