Adequate Insertion Depth of Dilator During Central Venous Catheterization

Not Applicable

• Conditions: Central Venous Catheterization
• Interventions: Procedure: dilator depth

• Registration Number: NCT04279808
• Lead Sponsor: Seoul National University Hospital

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.

Arm && Interventions

Group	Intervention	Description
measured distance	dilator depth	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."

Primary Outcome Measures

Name	Time	Method
hematoma realted with the dilator	1 Day (on the study day for each patient)	hematoma from the vascular wall puncture by the dilator

Secondary Outcome Measures

Name	Time	Method
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)	distance between skin puncture site and the outside of the anterior wall of the internal jugular vein which will be measured by real-time ultrasonography
