## Description

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.

Please note that a subscription is required to access all content for this app. You can purchase a monthly or yearly subscription after signing in.

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

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 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 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 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 in the app making it pleasant and time efficient to use.

## Review summary

Users praise AnSo for its realistic visuals, ease of use, and broad, comprehensive teaching content. However, major frustrations center on sign-in problems (Apple ID) and recurrent app instability after updates, with multiple reports of being unable to log in on Apple devices or iPads. Some mention device-specific compatibility issues. Improvements in offline capability, login reliability, and update stability would likely boost overall satisfaction.

### Pros

- Realistic, high-quality visuals for anesthesia and ultrasound, useful for learning and clinical teaching.
- Easy to use with an intuitive interface and quick loading times.
- Comprehensive content with multiple views, offering broad coverage for didactic and clinical use.
- Positive user sentiment and willingness to recommend to colleagues/trainees.

### Cons

- Persistent sign-in/login failures, especially with Apple ID across multiple devices.
- App instability or outages after updates, including cases of missing data or not functioning as expected.
- Device compatibility issues on Apple devices/iPad.
