AbstractArterial line cannulations frequently are performed in various clinical settings to facilitate hemodynamic monitoring and metabolic assessments. Palpation-guided technique generally is performed due to the superficial nature of the peripheral arteries; however, this approach may be challenging in patients with obesity, edema, and hypotension. Difficult line placements are a significant contributor of reduced operating room efficiency due to time delays seen in procedural workflow. Real-time ultrasound guidance is shown to improve success rates of arterial cannulation and reduction in multiple attempts, leading to time efficiency and less likelihood of arterial spasms or hematoma formation. In this report, the authors demonstrate the workflow of ultrasound-guided arterial line cannulation, outline the features of their institutional multi-modal training project for quality improvement, and evaluate the possible effect of the initiative on surgical delays seen with difficult line placements.Copyright © 2021.
