Distal versus conventional radial artery catheterization for hemodynamic monitoring in intensive care setting: a randomized, controlled, non-inferiority trial.

ABSTRACT:

Background

Arterial catheterization is fundamental for hemodynamic monitoring in critically ill patients, yet instability and loss of arterial pressure waveform remain clinically significant issues. The distal radial artery (dRA) approach has been proposed as a potential alternative to the conventional radial artery (RA) approach. This is the first randomized clinical trial to assess the comparative efficacy and reliability of dRA versus RA catheterization by examining first-attempt success rates and the stability of arterial pressure waveforms in critically ill ICU patients.

Methods

This randomized controlled trial enrolled 200 critically ill patients requiring arterial catheterization, assigning them to either dRA (n = 100) or conventional RA (n = 100) groups. All procedur
