What this trial studies

This study compares the effectiveness of supraclavicular and axillary brachial plexus nerve blocks in providing analgesia for adults undergoing arteriovenous (AV) fistula creation. Both techniques will be performed under ultrasound guidance using the same local anesthetic. A total of 120 patients will participate, with 60 receiving each type of nerve block. The study aims to evaluate the need for additional analgesia, the recovery rate, and the overall efficacy of these regional anesthesia techniques. An interim analysis will be conducted after 30 patients have been recruited for each technique.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are scheduled for AV fistula creation in the antecubital fossa.

Not a fit: Patients who are hemodynamically unstable, have local infections, or known allergies to local anesthetics may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and recovery for patients undergoing AV fistula creation.

How similar studies have performed: While there have been studies on brachial plexus blocks, this specific comparison using ultrasound guidance for AV fistula creation is novel.
