Ultrasound Evaluation of the Jugular Venous Pulse (US-JVP)

NCT03917368 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 300

No results posted yet for this study

Summary

The jugular venous pulse (JVP) reflects changes in the right atrial pressure and its evaluation can be useful in managing many emergency conditions for guiding the fluid administration as well as in the diagnosis and/or prognosis of many heart and lung diseases. The present study aims: i) To validate a novel ultrasonographic (US) technique for obtaining the JVP from a high-resolution B-mode sonograms sequence, recording the changes of the cross-sectional area (CSA) of the internal jugular veins (IJV) over the cardiac cycle; ii) To develop physical and mathematical models capable of providing an indirect estimate of central venous pressure (CVP) from the changes in IJV-CSA acquired through the US investigation, and iii) To test the transferability of the novel US-JVP technique in a clinical setting.

Conditions

Interventions

OTHER

Ultrasound scan of the internal jugular veins

Participants, lying at their hospital bed, will maintain their head in a fixed position on the longitudinal axis, while an operator gently places a linear probe L12-RS (7.5-11 MHz), smeared with gel, on one side of the neck, at the middle level. A 15-sec video clip of the ultrasound images will be recorded. This procedure will be repeated on the other side of the neck. In addition, three electrodes will be placed on participants' chests and connected to the ultrasound system for simultaneously measuring the ECG signal.
