Official Title: Development and Validation of an Ultrasound-Based Difficult Cannulation Risk Score for Pre-procedural Internal Jugular Vein Catheterization in Critically Ill Patients: A Prospective Observational Coho

Brief Summary: Ultrasound-guided internal jugular vein (IJV) catheterization is widely used in critically ill patients. Despite ultrasound guidance, difficult catheterization and first-pass failure remain clinically important and may increase the risk of mechanical complications. Pre-procedural characteristics of the IJV, its anatomical relationship with the common carotid artery (CCA), head rotation, and operator experience may influence procedural success.The ROTATE-ICU study is a prospective observational cohort study…
