UGIST: Ultrasound Guided Internal Jugular Short-Term Central Venous Catheters Tunneling (UGIST)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified March 2008 by McMaster University.
Recruitment status was:  Recruiting

The purpose of the study is to determine if tunneling standard short-term central lines for a short distance under the skin, with the assistance of ultrasound imaging, reduces the risk of central line infections for catheters placed in the neck vein.

Previous work has shown that these lines can be tunneled without ultrasound guidance. We wish to determine if the use of ultrasound makes the tunneling procedure safer and easier.

Arms Assigned Interventions
Active Comparator: 1
To Tunnel
Procedure: To tunnel
Using the standard Seldinger technique and under the guidance of ultrasound, the catheter will pass through a 3-5cm subcutaneous tunnel before it is eventually secured to reside at the internal jugular vein.
Active Comparator: 2
Not to tunnel
Procedure: Standard (not to tunnel)
Using the standard Seldinger technique and under the guidance of ultrasound, the catheter is secured to reside at the internal jugular vein, without a subcutaneous tunnel.

Detailed Description:

More than 250,000 vascular catheter-related bloodstream infections occur annually in the USA with a mortality ranging from 12% to 25% in critically ill patients.

It is also widely accepted that the internal jugular site is associated with a higher risk of catheter related infection if compared with the subclavian site.

Therefore, the benefit of catheter tunneling was best seen at the internal jugular site as described by J F Timsit in 1996 in his prospective randomized multicentre study where it significantly decreased the rate of catheter related sepsis from 11.4% to 3.4%.

At the same time, tunneling catheters did not increase the rate of mechanical complications such as pneumothorax, hematoma, or arterial puncture, but it almost doubled the rate of technical difficulties, such as problems with advancing the catheter or multiple puncture sites, at that time it was a blind technique.

Now, and with the introduction of the ultrasound guidance in our routine central line insertions, we would like to evaluate its benefit in reducing the technical difficulty and mechanical complications that used to be encountered while tunneling the short term central venous catheters at the internal jugular site.
