Anesthesia Providers’ Perceptions of Ultrasound-Guided Arterial Line Placements: A DNP Project

Abstract

Current evidence shows the use of ultrasound guidance is advantageous for arterial line placements in reducing complications and increasing efficiency. Despite this evidence, no formal guidelines have been established regarding ultrasound-guided arterial line placements, leaving anesthesia providers to use their clinical judgment and personal preferences when placing these invasive lines. At this time, there is a lack of understanding regarding anesthesia provider preference for utilization of ultrasound technology for perioperative arterial catheterization. The purpose of this DNP quality improvement project was to develop, implement, and evaluate the perceived adequacy of an educational resource designed specifically for anesthesia providers to improve awareness and utilization of ultrasound for arterial line placement. This project took place at the main operating suite of a large medical facility in eastern North Carolina. CRNAs at this site were provided information on the basics of ultrasound use, troubleshooting tips, and the current research regarding ultrasound-guided arterial line placements. The results showed that confidence level and likelihood of using ultrasound-guidance for arterial line placements increased following the implementation period. Participants also identified a lack of equipment as a barrier to using ultrasound in their practice. Future projects should focus on increasing access to ultrasound equipment and the addition of a hands-on ultrasound workshop to further increase confidence and skill.
