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 Cohort Study
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 designed to investigate pre-procedural ultrasound and clinical predictors of difficult IJV catheterization in critically ill adults. Consecutive adult intensive care unit patients undergoing ultrasound-guided IJV central venous catheterization will undergo standardized pre-procedural ultrasound assessment. IJV anterior-posterior diameter, skin-to-vessel depth, IJV position relative to the CCA, head rotation angle, operator experience, and relevant clinical and procedural characteristics will be recorded.
The primary objective is to develop and internally validate a clinical prediction model for cannulation difficulty and first-pass cannulation outcome. Secondary objectives include evaluating the relationship between head rotation and IJV morphology and describing the association between complete IJV collapse and procedural outcomes. The planned enrollment is 150 participants.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
Age ≥18 years. Admission to the intensive care unit. Clinical indication for central venous catheterization. Planned internal jugular vein access. Planned ultrasound-guided catheterization. Written informed consent obtained from the participant or legally authorized representative, where required.
Exclusion Criteria:
Active cardiopulmonary resuscitation at the time of catheterization. Neck anatomical abnormality preventing standard IJV assessment or catheterization.
Neck hematoma. Active local soft-tissue infection at the proposed access site. Planned vascular access through a site other than the internal jugular vein. Planned catheterization without ultrasound guidance. Refusal or inability to obtain required informed consent.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
