Ultrasound-Guided Arterial Catheterization in a Pediatric Patient

This video demonstrates an overview of radial arterial cannulation in a pediatric patient using real-time ultrasound (US) guidance.  Ultrasound imaging is a useful tool in the armamentarium for guiding arterial line placement, and its use has become commonplace due to increased accessibility and improved technology. Ultrasound imaging facilitates the detection of abnormal anatomy and abnormal findings (e.g. thrombosis). It also allows for real-time guidance for arterial cannulation, which is especially valuable during difficult insertions such as in neonates or small infants, patients with weak or absent pulses or landmarks, and those with multiple prior cannulations. There is evidence of higher success rates with first attempts and decreased complications compared to the traditional landmark and palpation techniques.
