University of Iowa
  Purpose
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.

Condition
Central Venous Pressure

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Use of Ultrasound to Determine Central Venous Pressure in Critically Ill Patients

Further study details as provided by University of Iowa:

Primary Outcome Measures:
  • Correlation of CVP measurement via ultrasound and central venous catheter [ Time Frame: 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:
  • Correlation of CVP measurement via physical examination of IJV and EJV. [ Time Frame: 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


Enrollment: 38
