Supraclavicular Block vs Retroclavicular Block: Incidence of Phrenic Nerve Paralysis

Phrenic Nerve Paralysis Clinical Trial

Official title:
Ultrasound Guided Supraclavicular Brachial Plexus Block vs Retroclavicular Brachial Plexus Block: Comparison of Impact on Ipsilateral Diaphragmatic Function

Clinical Trial Summary

The aim of this study is to evaluate differences between ultrasound guided supraclavicular versus retroclavicular brachial plexus blocks: two similar brachial plexus nerve block techniques that differ in their needle trajectory and injection site.

Clinical Trial Description

To date, there has not been a study that has compared clinically the retroclavicular brachial plexus block to the supraclavicular brachial plexus block or other brachial plexus blocks. The aim of this study is to evaluate differences between ultrasound guided supraclavicular versus retroclavicular brachial plexus blocks, with primary focus on the incidence of diminished ipsilateral hemidiaphramatic excursion (ipsilateral phrenic nerve blockade). We will also evaluate differences between the two techniques in the success of producing surgical anesthesia, procedural time to perform the block (including imaging time and needling time), block onset time, ease of quality ultrasound needle visualization, and incidence of paresthesias, vascular puncture and pneumothorax. Lastly, we will observe and compare the distribution of motor and sensory blockade of the two techniques ;
