Comparison of Traditional and Ultrasound-Guided Techniques for Vascular Access in Patients With Difficult Venous Access in Emergency Department.

The aim of this clinical trial is to compare the use of ultrasound versus the traditional palpation and visualization technique for vascular punctures, both peripheral venous and arterial punctures for arterial blood gas sampling, in patients presenting to hospital emergency departments. The main questions it seeks to answer are: Does the use of ultrasound facilitate peripheral venous cannulation in patients with difficult venous access in the emergency department? Does the use of ultrasound facilitate arterial puncture in patients presenting to the emergency department who require arterial blood gases? The researchers will compare the use of ultrasound with the traditional technique in vascular punctures by emergency department nurses. To determine the differences in the number of attempts needed, the number of professionals needed to perform the technique, the time invested, the pain produced with both techniques, etc., the researchers will compare the use of ultrasound with the traditional technique for vascular punctures by emergency department nurses.
