Non-tunneled Vs. Tunneled Catheters

Non-tunneled catheters are fixed in place at the site of insertion, with the catheter and attachments protruding directly. Commonly used non-tunneled catheters include Quinton catheters.

Tunneled catheters are passed under the skin from the insertion site to a separate exit site, where the catheter and its attachments emerge from underneath the skin. The exit site is typically located in the chest, making the access ports less visible than if they were to directly protrude from the neck. Passing the catheter under the skin helps to prevent infection and provides stability. Commonly used tunneled catheters include Hickman catheters and Groshong catheters.
