Adequate Insertion Depth of Dilator During Central Venous Catheterization

Adequate Insertion Depth of Dilator During Central Venous Catheterization Through the Right Internal Jugular Vein

For safe central catheterization, clinicians must be aware of adequate dilator insertion depth not to directly dilate the venous wall. The purpose of the study is to find out adequate insertion depth of the dilator during central venous catheterization through the internal jugular vein with the aid of real-time ultrasonography.

This randomized controlled trial is to compare the distance between the skin puncture site and the outside of anterior wall of the internal jugular vein measured by real-time ultrasonography with the conventional method which is routinely used in common clinical practice.

Inclusion Criteria:

• adult patients requiring central venous catheterization through the right internal jugular vein

Exclusion Criteria:

• suspicion for infection of the right neck site
