Infraclavicular Left Subclavian Vein in Neonates

The infraclavicular approach for subclavian vein puncture, extensively utilized under anatomical guidance, is characterized by a high incidence of complications and a low cannulation success rate in this age group, as documented in the medical literature. The adoption of dynamic needle tracking (DNT), necessitating the long-axis (LAX) visualization of the echogenic introducer needle, facilitates the visualization and cannulation of small-caliber veins, such as those in neonatal patients, thus minimizing the risk of complications. The most technically demanding aspect of this procedure is achieving precise alignment of the introducer needle with the insonation area of the transducer; mastering this step enhances cannulation efficacy and significantly reduces apprehension regarding complications associated with this vascular access technique.
