About this trial

This prospective observational study aims to evaluate the diagnostic utility of vascular ultrasound for internal jugular vein (IJV) assessment in adult patients undergoing clinically indicated IJV cannulation.

Traditionally, bedside clinical assessment of jugular venous pressure (JVP) is challenging and frequently imprecise in critically ill or obese individuals. This study investigates whether non-invasive ultrasound parameters, specifically IJV diameter, collapsibility index, and Doppler flow patterns, can reliably estimate central venous pressure (CVP) and identify elevated JVP.

Participants admitted to the Intensive Care Unit, Emergency Department, or Operating Theatres who require right IJV catheterization will receive a standardized pre-procedural vascular ultrasound evaluation in a supine position (0-30° head elevation) prior to routine, ultrasound-guided cannulation. Ultrasound measurements will then be compared to direct central venous pressure readings to assess diagnostic accuracy and correlation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adult patients aged 18 years or older.

Patients admitted to the Intensive Care Unit (ICU), Emergency Department, or Operating Theatres who require internal jugular vein (IJV) cannulation for clinical indications.

Patients in whom ultrasound-guided right internal jugular vein cannulation is planned.

Patients who are hemodynamically stable enough to undergo ultrasound examination before cannulation.

Disqualifiers

Patients younger than 18 years of age.

Previous surgery, radiotherapy, or significant trauma involving the neck.

Known thrombosis, stenosis, or congenital anomalies of the internal jugular vein.

Local infection, cellulitis, burn, or hematoma at the intended cannulation site.

Trial population

Adult patients aged 18 years or older admitted to the Intensive Care Unit (ICU), Emergency Department, or Operating Theatres at Assiut University Hospitals who require ultrasound-guided right internal jugular vein (IJV) cannulation and hemodynamic assessment for clinical indications.

Trial outcomes

Primary outcomes

Internal Jugular Vein Collapsibility Index Percentage

The Internal Jugular Vein (IJV) collapsibility index is evaluated by bedside vascular ultrasound and calculated using the formula: \[(maximum anterior-posterior diameter during expiration - minimum anterior-posterior diameter during inspiration) / maximum anterior-posterior diameter during expiration\] \* 100. The outcome is reported as a continuous percentage from 0% to 100%, where higher values indicate greater vein collapsibility
