Advantages of the use of ultrasound in newborn vascular access: a systematic review.

Abstract

Vascular access in neonates and small infants is often challenging. Ultrasound (US) screening and guidance improves its safety and efficacy. The advantages of a pre-implantation ultrasound examination are intuitive; it is a practical and safe technique that doesn't use radiation, allowing static and dynamic evaluations to be carried out and identifying anatomical variations, the caliber and depth of the vessel, the patency of the entire course and attached structures (nerves, etc.). Optimization of the image is a crucial aspect in achieving a clear view of all anatomical structures while avoiding complications. The goal of this review was to look into the benefits of using US in invasive catheter insertion procedures, especially in pediatric patients. Ultrasonography is used to visualize vessels and related structures in two dimensions (2D), sometimes with the help of color Doppler to detect the presence of intraluminal thrombi by applying gentle compression to assess vessel collapse and evaluate morphologic changes in the internal jugular vein (IJV) who had undergone central venous catheter (CVC) insertion during the neonatal period (Montes-Tapia et al. in J Pediatr Surg 51:1700-1703, 2016).
