Conditions
Keywords
internal jugular vein, cross sectional area, ultrasound, central venous pressure
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.
