What this trial studies

This clinical research focuses on enhancing the safety and accuracy of radial artery puncture catheterization in surgical patients by utilizing ultrasound technology. The study measures anatomical parameters of the radial artery and radial nerve in the forearm to identify the optimal puncture locations. A total of 100 surgical patients will be included, who will be randomly assigned to different groups based on the puncture site. The aim is to reduce the number of punctures and complications associated with the procedure.

Who should consider this trial

Good fit: Ideal candidates are surgical patients aged 18-65 who are planning to undergo general anesthesia and invasive arterial blood pressure monitoring.

Not a fit: Patients with peripheral vascular diseases, local skin infections, or those unable to cooperate with ultrasound assessments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to safer and more accurate catheterization procedures for surgical patients.

How similar studies have performed: While the use of ultrasound in vascular access is established, this specific approach to optimizing radial artery catheterization is novel and has not been extensively tested.
