Adequate Insertion Depth of Dilator During Central Venous Catheterization Through the Right Internal Jugular Vein
Trial Snapshot
- Phase
- Not Applicable
- Enrollment
- 68
- Primary Endpoint
- hematoma realted with the dilator
Study Overview
Brief Summary
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.
Detailed Description
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.

Arms & Interventions
measured distance
In the modified Seldinger's maneuver, after guide-wire insertion into the right internal jugular vein, "we will measure the distance between the skin puncture site and the outside of anterior wall of the jugular vein. Next, we will insert the dilator on the guidewire by the measured length."
Intervention: dilator depth (Procedure)
conventional method
In the modified Seldinger's maneuver, after guide-wire insertion into the right internal jugular vein, "we will insert the dilator on the guidewire as commonly used method of the practitioners."
Outcomes
Primary Outcomes
hematoma realted with the dilator
Time Frame: 1 Day (on the study day for each patient)
hematoma from the vascular wall puncture by the dilator
Secondary Outcomes
- distance between skin puncture site and the outside of the anterior wall of the internal jugular vein(1 Day (on the study day for each patient))
