Arterial

Ultrasound-guidance is an invaluable technique for arterial catheterization. Compared with palpation, studies have shown ultrasound-guided radial artery catheterization has a shorter time for identification of the artery, an increased rate of success, fewer attempts to successful cannulation, and less hematomas--all statistically significant. Whether you're in the OR, helping out in the PICU, or in the pediatric cath lab, the use of an ultrasound should be seen as less of a crutch, and more of secret weapon. Using a sledgehammer to crack a nut, it most certainly is not!

Real-time imaging of the needle piercing the vessel requires significant hand-eye coordination. As such, routine use of this skill is highly recommended.  It becomes even more important for neonates and infants whose radial arteries have a cross-sectional areas in millimeters!  Practicing in more routine clinical situations will prepare you for doing it in more critical scenarios.
