Comparison of Brachial Compression Versus Ulnar Compression on Radial Artery Diameter: A Randomized Controlled Trial

Abstract

Conclusion: Ulnar compression and brachial compression maneuvers demonstrated effectiveness in inducing radial artery dilation for a limited duration. These maneuvers may reduce the occurrence of access failure during radial artery cannulation. No significant differences were observed between the two maneuvers, indicating that they can be used interchangeably based on clinician preference. So, because the ulnar compression is simpler and more feasible for the patients, it can be considered instead of brachial compression.
