Static Ultrasound Guidance for Radial Arterial Puncture

Summary

Radial arterial puncture is a commonly performed procedure in emergency departments for arterial blood gas analysis and invasive hemodynamic monitoring. The conventional palpation technique may be associated with prolonged procedure duration and multiple puncture attempts, particularly in patients with weak arterial pulsation or difficult vascular anatomy.

Ultrasound guidance has been proposed as a method to improve procedural success. This randomized controlled trial aimed to compare the static ultrasound-guided technique with the conventional palpation technique for radial arterial puncture in adult emergency department patients.

The primary outcome was puncture duration. Secondary outcomes included first-attempt success rate, total number of attempts, procedure-related complications, and patient pain scores.

Conditions

  • Arterial Blood Gas Analysis

Interventions

PROCEDURE

Static Ultrasound-Guided Radial Arterial Puncture

Static ultrasound guidance was used to identify and externally mark the radial artery location prior to arterial puncture.

PROCEDURE

Conventional Palpation Technique

Radial arterial puncture was performed using anatomical landmarks and palpation without ultrasound guidance
