RESUMEN
Background: The aim of this description is to provide step-by-step guidelines for performing an ultrasound-guided supraclavicularbrachial plexus nerve block. Methods: The brachial plexus in the supraclavicular fossa of sixty healthy volunteers was scanned in the horizontal/transverse plane. The relevant regional anatomy was studied to identify the muscular and vascular structures seen on the ultrasound screen. Results: The entire process was documented and a standard, step-by-step guide to performing ultrasound-guided supraclavicular brachial plexus blocks was developed. Conclusion: This description serves as a comprehensive guide to a technique for performing ultrasound-guided supraclavicular brachial plexus blocks safely and successfully. It also aims to provide the reader with the background knowledge of the technique and the surrounding regional anatomy
