Summary

The retrograde infraclavicular brachial plexus block has been proved an effective and safe approach. Realtime ultrasound guide will facilitate a successful peripheral nerve block. The purpose of this study was to determine the medium effective volume required to produce an effective retrograde infraclavicular block using an ultrasound (US)-guided technique.
