Ultrasound-Guided Vascular Access: In-Plane Approach
The transducer is held stationary with the non-dominant hand while advancing the needle using the dominant hand.
The in-plane or long access approach is the technique used to allow visualization of the entire needle when performing ultrasound-guided vascular access.
The transducer is positioned in a long axis over the selected vein. The vessel is visualized straight across the screen. The needle is placed at the center of the transducer in-line with the ultrasound beam and the trajectory of the vessel with the bevel up.
