An Alternate In-Plane Technique of Ultrasound-Guided Internal Jugular Vein Cannulation.

<bold>Background: </bold>Commonly used ultrasound-guided internal jugular vein (IJV) cannulation techniques, short axis out of plane and long axis in-plane, have significantly reduced complications but failed to eliminate them because of technical difficulties.<bold>Objective: </bold>This article describes a new anteroposterior short axis in-plane technique that combines advantage of in-plane technique to track the needle tip and short axis view of visualizing nearby anatomical structures by placing the probe on the side of the neck, oriented anteroposteriorly, perpendicular to the long axis of neck. This view visualizes IJV and its relationship to the carotid artery in short axis. The puncture needle is passed in-plane anteroposteriorly from the anterior aspect of the neck. Visualizing the needle, carotid artery, and IJV in single frame minimizes complications.<bold>Methods: </bold>A prospective evaluative clinical trial was conducted in patients who require IJV cannulation for various reasons by performers experienced in ultrasound-guided IJV cannulations. The efficacy of the technique is indicated by 3 primary outcome measures: access time, number of attempts and success rate, and safety by secondary outcome measure, which is the incidence of mechanical complications.<bold>Results: </bold>Seventy-five patients were enrolled. The average number of attempts was 1.17 (standard deviation 0.44), the access time was 27.12 s (standard deviation 21.47), and the success rate was 100%. This technique had 12% incidence of posterior venous wall punctures and 2.66% misplacements and no other complications.<bold>Conclusion: </bold>Anteroposterior short axis in-plane technique is relatively novel and could be alternatively used safely and effectively in place of existing techniques for IJV cannulation.
