About this study

Objectives:

  • To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound.
  • To evaluate the correlation of internal jugular vein cross sectional area and central venous pressure.

Methods:

  • The study design is prospective observational study.
  • 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.
  • The data will be analyzed.
