Arterial Cannulation

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.

This is a two-phase study evaluating the Eurosets arterial and venous cannulas for use during cardiopulmonary bypass (CPB) procedures. Phase 1 is a pilot study focused on assessing cannula safety. Phase 2 is a pivotal study aimed at confirming safety and evaluating efficacy through comparison with Medtronic cannulas (control group). The results will be compared for non-inferiority with those obtained using the control group cannulas.
