What this trial studies

This study aims to compare the effectiveness of proximal versus distal radial artery cannulation using ultrasonography for patients undergoing elective surgery. Patients will be monitored throughout the procedure, and their demographic and clinical characteristics will be recorded. The study will assess procedural success rates, duration, complications, and other relevant factors to determine the best approach for arterial catheterization. Participants will be divided into two groups based on the cannulation site, and outcomes will be evaluated postoperatively.

Who should consider this trial

Good fit: Ideal candidates are patients undergoing elective surgery with an ASA physical status of I-III.

Not a fit: Patients with emergency surgeries, severe comorbidities, or anatomical abnormalities at the cannulation site may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the safety and efficiency of arterial catheterization in surgical and intensive care settings.

How similar studies have performed: Previous studies have shown varying success with different approaches to arterial cannulation, but this specific comparison is less commonly explored.
