About this study
Official title: Comparison of Ultrasonographic Measurements of Radial and Ulnar Arteries in Pediatric Patients Undergoing Elective Surgery
Ultrasound measurements of the ulnar artery and radial artery at different angles are obtained and compared to determine the optimal diameters for possible arterial cannulation in pediatric patients.
Read the detailed description
Radial artery cannulation is the most commonly used technique for invasive arterial catheterization in pediatric patients. Ultrasound guidance has significantly reduced cannulation success rates and complication risks. The ulnar artery presents an anatomical alternative to the radial artery and has emerged as a potential cannulation site. This study aims to comprehensively evaluate the suitability of the radial or ulnar artery for cannulation in pediatric patients.
Finding of this study objectives are
To obtain a large sample of pediatric patients from different age groups To measure arterial diameters using ultrasound at different angles and with ultrasound and to assess the optimal artery and the angle.
- Conditions
- Ulnar and Radial Artery
- Keywords
- ultrasonography for cannulation, pediatrics
What is being measured
The primary outcome is the main question the study is designed to answer.
Determining the Diameter and Depth at different angles
The study aims to measure the radial and ulnar arteries using ultrasound at different angles to determine the widest diameter and the optimal angle to achieve this diameter.
Measured: only once
Comparing Ulnar and Radial Artery Diameters Across Age Groups
Investigating whether there is a difference (ulnar>radial, ulnar=radial, or radial>ulnar) in the diameter of the ulnar artery compared to the radial artery among the age groups included in the study
Measured: only once
