Adequate Insertion Depth of Dilator During Central Venous Catheterization

NCT ID: NCT04279808

Last Updated: 2020-03-06

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: NA
• Total Enrollment: 68 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2020-03-31
• Study Completion Date: 2021-01-31

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.

Conditions

Central Venous Catheterization

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: DOUBLE

Study Groups

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."

Group Type: EXPERIMENTAL

dilator depth

Intervention Type: PROCEDURE

For soft tissue dilation just after guidewire insertion in central venous catheterization through the right internal jugular vein, investigators will measure the distance between the skin puncture site and outside of anterior wall of the vein with real-time ultrasonography in the measured depth group. Next, practitioner will insert the dilator by the measured length and continue to insert the central venous catheter. For the conventional group as a control group, practitioner will perform the central venous catheterization with a manner used routinely by the practitioner.

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."
