An interventional study of Dynamic needle tip positioning under ultrasound-guidance and Conventional long-axis view in Cardiac Surgical Procedures, Central Venous Catheterization and Ultrasonography, sponsored by Seoul National University Hospital. Completed at 1 site in Korea, Republic of. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-02-28.

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.
Seoul National University Hospital is the lead sponsor of 1,860 studies on the registry; 275 are open to participants now.
Of its 12 completed or terminated interventional studies of FDA-regulated products, 2 (17%) have results posted.
