Central Venous Pressure (CVP) Assessment by Ultrasound and Physical Examination
Completed
- Conditions
- Central Venous Pressure
- Registration Number
- NCT01099241
- Lead Sponsor
- University of Iowa
- Brief Summary
Ultrasound may be useful for noninvasively determining the central venous pressure. We intend to compare the clinical examination of the neck veins; ultrasound delineation of the internal jugular vein; and the central venous pressure measured with an intravascular catheter.

Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 38
Inclusion Criteria
- adult medical or surgical ICU patients who have preexisting central venous (jugular/subclavian only) catheters.
Exclusion Criteria
- subjects with only a femoral venous catheter.
- subjects whose CVP measurement by the indwelling catheter exceeds 20cm of water.
- subjects younger than 18 years old.
- inability to obtain informed consent from the subject or the subjects authorized representative.
Study & Design
- Study Type
- OBSERVATIONAL
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Correlation of CVP measurement via ultrasound and central venous catheter At data collection: this is a physiologic study CVP as determined non-invasively with the transcutaneous ultrasound probe will correlate with a high degree of accuracy to the measurement obtained invasively by the catheter and pressure transducer.
- Secondary Outcome Measures
Name Time Method Correlation of CVP measurement via physical examination of IJV and EJV. At data collection: physiologic study Despite its more tortuous course and smaller caliber, the external jugular vein will be as reliable (compared to the catheter) as the internal jugular to estimate CVP
