nerveblox® by Pajunk

Artificial Intelligence for Ultrasound-Guided Nerve Block Training

Ultrasound-Guided Nerve Block Training has developed throughout the decades and has driven the popularity of Regional Anaesthesia.

Starting with the paresthesia technique, then nerve stimulation to ultrasound-guided techniques, new blocks have emerged and allowed practitioners to perform safer regional anaesthesia for an ever-growing spectrum of medical procedures. The introduction of ultrasound into regional anaesthesia was a pivotal step. However, it also brought some additional complexity related to reading and interpreting the sono-anatomy picture and combining the anatomy knowledge of the practitioner and the tactile feel and placement of the needle.

Based on current studies1, AI technology can successfully interpret anatomical structures in real-time sonography assisting aneasthesiologists during ultrasound-guided nerve block procedures.

The nerveblox AI is continuously being improved in our laboratories, allowing for a better recognition of anatomical structures. Currently, the system knows the anatomy of the following blocks:
