Arterial cannulation is frequently used for continuous blood pressure monitoring and blood sampling in the operating room and intensive care unit. Arterial cannulation in pediatric patients is challenging, even for experienced anesthesiologists. In this issue of Anesthesiology, Kim et al. evaluated the posterior tibial artery as an alternative arterial cannulation site to the radial artery in small children using ultrasound guidance. In an accompanying Editorial View, Adler and Litman advocate for the standard use of ultrasound guidance to facilitate arterial cannulation in children of all ages, and for practitioners to use this technique to evaluate alternate cannulation sites, in addition to the radial artery, when invasive monitoring is required.
