Interventional
Description of intervention(s) / exposure
Common management for both groups will include the following:

1. No pre-medication
2. Standard monitoring: ECG, non invasive blood pressure, oxymetry.
3. Peripheral venous cannulation

Supraclavicular (SB) group:
Supraclavicular block
15 ml lidocaine 2% + 15 ml bupivacaine 0.5% in a double point injection ultrasound guided supraclavicular brachial plexus block

Infraclavicular (IB) group:
Infraclavicular block
15 ml lidocaine 2% + 15 ml bupivacaine 0.5% in a triple point injection ultrasound guided infraclavicular brachial plexus block

The duration of each procedure is approximately 15 minutes

Summary
Brief summary
To determine whether ultrasound guided supraclavicular block provides more important increase in brachial artery blood flow and more important vasodilation of the cephalic vein than infraclavicular block.
If the primary hypothesis is confirmed, this study will provide evidence supporting the use of the supraclavicular block for the confection of humeral-cephalic arteriovenous fistula.
