Dynamic SAX vs Conventional LAX in Internal Jugular Vein Catheterization

Conventionally, short-axis out-of-plane (SAX) or long-axis in-plane (LAX) ultrasound views are commonly used to guide internal jugular vein catheterization.

SAX dynamic needle tip positioning (SAX-DNTP) is a novel ultrasound imaging technique that enables continuous visualization of the needle tip during ultrasound-guided cannulation; When the needle tip is imaged as a hyperechoic dot, the ultrasound probe is moved a few millimeters, and then the needle is advanced until the needle tip reappears in the vessel lumen. The process is repeated until the needle is advanced more than 1 cm into the lumen. The catheter is then introduced into the vessel.

The aim of this study was to compare the first pass success rate of internal jugular vein catheterization between SAX-DNTP and the conventional LAX technique.
