Summary

Radial artery cannulation is a routine procedure for invasive hemodynamic monitoring for patients undergoing cardiovascular surgery patients.

Although ultrasound (USG) guidance is known to improve success rates, there is limited data comparing the efficacy of the 'Direct' versus 'Seldinger' techniques specifically in patients with anticipated difficult radial access.

This study aims to compare the effectiveness of USG-guided Direct cannulation and USG-guided Seldinger techniques in adult patients with anticipated difficult radial arterial cannulation.

Conditions

  • Cardiac Surgery in Adult Patient
  • Cardiac Surgery
  • Radial Artery Cannulation
  • Arterial Cannulation

Interventions

PROCEDURE

Ultrasound-Guided Direct Cannulation Technique

Radial artery cannulation performed using the direct puncture technique (catheter-over-needle) under real-time ultrasound guidance.

PROCEDURE

Ultrasound-Guided Seldinger Cannulation Technique

Radial artery cannulation performed using the Seldinger technique (catheter-over-guide-wire) under real-time ultrasound guidance.
