Introduction. The article presents the results of a combination of ultrasound diagnostics and neurostimulationof axillary blockade in patients undergoing surgery on the upper extremity. Purpose. Introduction of axillary block of the brachialplexus under the simultaneous control of ultrasound and neu-rostimulatorto the clinical practice. Materials and methods: The study included 15 patients undergoing regional anesthesia under ultrasound and neu-rostimulator control. The examination was performed using a Zonare One ultrasound device using a high-frequency linear sensor. Stimuplex HNS 12 (BBraun) neurostimulator was used. As a local anesthetic used a 0.5% solution of bupivacaine. Results of the study and discussion. Patients underwent axillary block of the brachial plexus. Efectiveness ofanesthesia was determined on a digital rating scale, from 1 to 10. In 13 patients, the score was “0” until 7 hours after the block. The use of ultra-sound makes it possible to visualize anatomical structures even at their atypical location, and to bring the needle to these struc-tures under direct vision control. This greatly speeds up the manipulation and reduces the risk of an inefficient block. Conclusion. The combination of ultrasound imaging and neurostimulation to block the nerves of the brachial plexus from axillary access allows one to obtain a sufficient level of anesthesia and reduce the risk of unintended vascular puncture in all cases.
