A review of the anatomy and a step-by-step visual guide to performing an ultrasound-guided infraclavicular brachial plexus block

Abstract

BACKGROUND : The aim of this description is to provide step-by-step guidelines for performing an ultrasound-guided infraclavicular brachial plexus nerve block. METHODS : The brachial plexus in the infraclavicular 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 vertical infraclavicular brachial plexus blocks was developed. CONCLUSION : The development of high-resolution ultrasound guidance has allowed for the direct visualisation of the brachial plexus when performing nerve blocks. Ultrasound-guided infraclavicular brachial plexus nerve blocks are becoming more popular. This description aimed to provide step-by-step guidelines on how to perform this block safely and efficiently.
