Estimation of Internal Jugular Vein Central Venous Pressure (CVP) by Ultrasound

Completed

• Conditions: Internal Jugular Size Measured by Ultrasound; Central Venous Pressure
• Interventions: Diagnostic Test: cross sectional area

• Registration Number: NCT00904358
• Lead Sponsor: Mahidol University

Brief Summary

To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound.

Detailed Description

Objectives:

1. To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound.

2. To evaluate the correlation of internal jugular vein cross sectional area and central venous pressure.

Methods:

1. The study design is prospective observational study.

2. We will include all patients scheduled for cardiac surgery in Siriraj Hospital and record both internal jugular size using 2-dimensional ultrasound just before central venous catheter insertion. The central venous pressure will be recorded and the ultrasound picture will be measured.

3. The data will be analyzed.
