Summary

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.

Conditions

  • Arterial Blood Pressure
  • Difficult Vein Access

Interventions

PROCEDURE

peripheral venous cannulation with ultrasound-guided technique

Peripheral venous cannulation with short peripheral vascular access device, performed by ultrasound technique.

PROCEDURE

Arterial gas puncture using ultrasound-guided technique

Arterial puncture using a needle and heparinised syringe to extract a sample for arterial blood gas analysis, using the ultrasound-guided technique.

PROCEDURE

Peripheral venous cannulation with traditional technique

Cannulation of a short peripheral vascular access device using the traditional visualisation and palpation technique.

PROCEDURE

Arterial puncture by traditional technique

Arterial puncture using a needle and heparinised syringe to extract an arterial blood sample for arterial gamosetry analysis, performed using the traditional arterial pulse palpation technique.
