ScanNav Anatomy PNB will help tip the balance of safety and confidence in favour of performing regional anaesthesia. Our aim is to make a real clinical difference to patients by increasing the availability of regional anaesthesia through cutting edge technology

ScanNav Anatomy uses the latest AI technology to automatically highlight the live ultrasound image and make it easier to identify key anatomical structures. It supports the performance of healthcare professionals who are suitably qualified, but who perform ultrasound-guided procedures on a less frequent basis. It also enhances the accuracy and standardisation of ultrasound image interpretation by making it easier to identify key anatomical structures.

ScanNav Anatomy Peripheral Nerve Block

Ultrasound-guided peripheral nerve blocks are increasingly being used as a prudent alternative to general anesthesia, but not all anesthetists have the specialist knowledge of ultrasound anatomy to perform them.

Available in the UK as a stand-alone device, mounted on a portable cart that can be plugged into existing anesthesiology ultrasound machines, ScanNav Anatomy Peripheral Nerve Block supports nine common peripheral nerve blocks. Clinicians get continuous feedback from real-time highlighting of key anatomical structures relevant to the block on their live ultrasound. The system’s integrated reference material, including 3D animations relating the ultrasound view to the underlying anatomy, allows users to re-familiarize themselves with blocks that they carry out less frequently.

Through the adoption of ScanNav Anatomy PNB, it is hoped that hospitals will be able to increase the number of ultrasound-guided nerve blocks that they can perform.

Clinical validation

In a validation study regional anesthesia experts judged the AI-driven colour highlighting to be helpful:

  • for identifying anatomical structures in 1,330/1,334 cases (99.7%)
  • for confirming the correct ultrasound view in 273/275 ultrasound scans (99.3%)
