Comparing ulnar and radial artery cannulation in young children

Ulnar Artery Versus Radial Artery Cannulation in Paediatric Patients: a Prospective Randomized Non-inferiority Study

Not applicable Interventional Brno University Hospital · NCT05258903

This study is testing whether using the ulnar artery instead of the radial artery for placing catheters in young children needing surgery or critical care is safer and more effective.

What this trial studies

This study investigates the safety and effectiveness of ulnar artery cannulation compared to radial artery cannulation in pediatric patients requiring arterial access for high-risk surgeries or critical care. It involves a randomized approach where eligible patients aged 1 to 6 years will be assigned to either the ulnar or radial artery group for catheterization. The study aims to measure the success rate of catheter placement and the incidence of complications associated with each method. Ultrasound guidance will be utilized to enhance the accuracy of the cannulation process.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 1 to 6 years undergoing high-risk surgery or admitted to the pediatric intensive care unit with respiratory or circulatory failure.

Not a fit: Patients who refuse to participate or for whom arterial catheterization is not clinically relevant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer arterial access methods for pediatric patients, reducing complications associated with traditional cannulation sites.

How similar studies have performed: Previous studies have explored alternative cannulation sites, but this specific comparison of ulnar versus radial artery cannulation in pediatric patients is relatively novel.
