Dynamic Needle Tip Positioning for Ultrasound-Guided Arterial Catheterization in Infants and Small Children With Deep Arteries: A Randomized Controlled Trial

Combined short‐ and long‐axis method for internal jugular vein catheterization in premature newborns: A randomized controlled trial

“…Fernando 11 showed that ultrasound‐guided internal jugular vein catheterization with real‐time visualization in low‐birth‐weight newborns is effective and safe. The overall success rate was 94%, with a median of 2 1‐8 attempts, but this study did not discuss specific puncture methods. In recent years, many studies have reported the use of ultrasound‐guided cannulation of the subclavian vein (SCV) or brachiocephalic vein (BCV) in children and neonates.…”

“…This technique requires that the blood vessel, the ultrasound beam and the needle tip are all on the same plane under the short axis, and the position of the needle tip in the blood vessel can be dynamically monitored in real time. Takeshita 21,22 demonstrated that the DNTP method significantly improved the entire process of paediatric arterial and venous catheterization, significantly increased the success rate and reduced the number of attempts and the operation time. Although the needle tip could be traced easily using ultrasound during puncture, the superficial veins of this study population were easily compressible and mobile, and the diameters were small, which led to technical challenges in puncture and catheterization.…”

“…Ultrasound‐guided short‐axis dynamic needle tip positioning (DNTP) is an out‐of‐plane technique experienced physicians use to perform vascular catheterization 5 . Previous studies have suggested that it has significant advantages over the traditional puncture method for small blood vessels that can significantly improve the success rate, shorten the operation time and reduce the occurrence of complications 6 . However, premature infants have poor development, with small vessel diameters that are compressible.…”

Simulation-based training using a vessel phantom effectively improved first attempt success and dynamic needle-tip positioning ability for ultrasound-guided radial artery cannulation in real patients: An assessor-blinded randomized controlled study

“…The key elements, such as dynamically positioning the needle-tip or midline puncture of the radial artery anterior wall are known to increase the success rate. [28] Thus, ultrasound-guided procedures which were performed with missing the key elements may be difficult to evaluate as proficient skill acquisition of ultrasound-guided cannulation.…”

Ultrasound-guided peripheral vascular catheterization in pediatric patients: a narrative review

“…2 a–f and Additional file 2). Thus, due to DNTP providing a much better tracing of the needle tip, it is considered to complement the SAX-OOP approach in terms of “real time.” To support this, DNTP has been shown to have a greater first-attempt (peripheral venous catheterization, 86.7 vs. 60%; arterial catheterization, 85 vs. 50%) and overall success rate (peripheral venous catheterization, 90 vs. 63.3%; arterial catheterization, 95 vs. 60%) in ultrasound-guided vascular catheterization in pediatric patients than the “static” SAX-OOP approach [ 31 , 38 ]. However, as described above, DNTP consists of a series of precise techniques, and sufficient experience in ultrasound guidance is required to adequately perform this procedure in smaller children [ 39 ].…”
