Pressure Monitoring–Augmented Long-Axis In-Plane Versus Long-Axis In-Plane Alone for Ultrasound-Guided Radial Artery Catheterization in Elderly Patients Undergoing Coronary Artery Bypass Grafting: A Randomized Prospective Trial

Pressure monitoring combined with ultrasound-guided long-axis in-plane catheterization is an improved technique. In this study, it helped junior operators achieve higher success rates of radial artery catheterization in elderly patients undergoing coronary artery bypass grafting compared with the conventional long-axis in-plane technique.
