COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
Perpheral nerve blocks are known to induce many changes in the local circulation such as vasodilation. We use the ultrasound-doppler to show and quantify the variations of the regional hemodynamics of the upper arm after an infraclavicular brachial plexus block.
