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.

Famous quotes containing the word tunneled:
“It was a cruel city, but it was a lovely one, a savage city, yet it had such tenderness, a bitter, harsh, and violent catacomb of stone and steel and tunneled rock, slashed savagely with light, and roaring, fighting a constant ceaseless warfare of men and of machinery; and yet it was so sweetly and so delicately pulsed, as full of warmth, of passion, and of love, as it was full of hate.”
—Thomas Wolfe (1900–1938)
