About

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

Full 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.

Enrollment: 130 patients
