The preferred site of insertion (including for non-tunneled catheter placement), from an infection prevention point of view, is in the subclavian vein, and to generally avoid the femoral vein if possible. There is no clear recommendation for a tunneled catheter site in the guidelines.
Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as for chemotherapy.Similar to the Hickman line, the tip of the catheter is in the superior vena cava, and the catheter is tunneled under the skin to an incision on the chest wall, where the distal end of the catheter exits the body.
The catheter is inserted into the vessel under ultrasound or fluoroscopic guidance and tunneled through the skin. Tunneled catheters have multiple channels called lumens which lay exposed on the surface of the skin. These lumens are the access points when the catheter is used. Tunneled catheters can be single, double, or triple lumened.
Most common complications with venous access are catheter related infections, thrombophlebitis and venous thrombosis. If having thrombophlebitis or thrombosis; pain when using the access is another complication. Peripheral venous access is least prone to thrombosis, followed by midline catheters and the centrally placed catheters.
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
A Hickman line, a type of tunneled catheter, inserted through the skin at the chest and tunneled to insert into the jugular vein in the throat. A tunneled line is a type of central access which is inserted under the skin, and then travels a significant distance through surrounding tissue before reaching and penetrating the central vein.
The tunneled vs non-tunneled portion was well defined with links to the different catheters if further reading were desired. The implanted ports section was also well written with an appropriate picture accompanying the section.
The catheter is introduced into the vein by a needle (similar to blood drawing), which is subsequently removed while the small plastic cannula remains in place. The catheter is then fixed by taping it to the patient's skin or using an adhesive dressing. A peripheral venous catheter is the most commonly used vascular access in medicine.
