Direct vs. Seldinger Technique for Ultrasound-Guided Difficult Radial Access in Cardiac Surgery
Sponsor: Diskapi Teaching and Research Hospital
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.
