About

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.

Full 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.

Enrollment: 68 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

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

Exclusion criteria

• suspicion for infection of the right neck site

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

Experimental group

Description:

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."

Treatment:

Procedure: dilator depth

conventional method

No Intervention group

Description:

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."
