Optimizing precision in ICU arterial access: the impact of ultrasound-guided dynamic needle tip positioning.

ABSTRACT:

Objective

This study aims to evaluate the efficacy of ultrasound-guided dynamic needle tip positioning (DNTP) in arterial puncture and catheterization among ICU patients.

Methods

A cohort of 55 patients in shock, requiring arterial catheterization in the ICU from April 2020 to July 2024, was enrolled and randomly stratified into groups based on distinct ultrasound-guided puncture techniques. Of these, 27 patients who underwent the ultrasound-guided direct entry (UGDE) method were designated as the control group, while 28 patients who received arterial catheterization via the ultrasound-guided DNTP technique were assigned to the observation group. Comparative analyses were conducted on the first-attempt puncture success rate, first-attempt catheterization success rate, punctu
