Ultrasound-Guided Ulnar Versus Radial Artery Cannulation in Children
Sponsor: Tunis University
Summary
Arterial catheterization provides continuous blood pressure monitoring and repeated blood sampling in children undergoing surgery at high cardiovascular or hemorrhagic risk, and in critically ill children. The radial artery is the conventional site, but cannulation remains challenging in children because of small vessel caliber and frequent anatomical variants. Ultrasound guidance has made alternative sites accessible, and the ulnar artery has a comparable caliber and a depth often closer to the range considered optimal for puncture. This trial compared ultrasound-guided ulnar versus radial arterial cannulation in children older than one year, with regard to first-attempt success and the rate of local complications.

Interventions
Radial artery cannulation
The radial artery is identified sonographically at the anterior aspect of the wrist and confirmed with Doppler, with the wrist in 45 degrees of dorsiflexion. It is punctured through a short-axis out-of-plane approach using a 25-gauge 4 cm catheter and a Sonosite M-Turbo system with a 6-13 MHz linear probe.
Ulnar artery cannulation
Identical procedure applied to the ulnar artery.
