The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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.
