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.
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.
A peripherally inserted central catheter, or PICC line (pronounced "pick"), is a central venous catheter inserted into a vein in the arm (via the basilic or cephalic veins) rather than a vein in the neck or chest. The basilic vein is usually a better target for cannulation than the cephalic vein because it is larger and runs a straighter course ...
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. Central venous access is the most common reason for venous thrombosis in children. [citation needed]
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 dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens: venous and arterial. Although both lumens are in the vein, the "arterial" lumen, like natural arteries, carries blood away from the heart, while the "venous" lumen returns blood towards the heart.
A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein . A Hickman line is a central venous catheter most often used for the administration of chemotherapy or other medications, as well as for the withdrawal of blood for analysis.
The passage of the catheter may be monitored by dynamic pressure readings from the catheter tip or with the aid of fluoroscopy. The standard pulmonary artery catheter has two lumens (Swan-Ganz) and is equipped with an inflatable balloon at the tip, which facilitates its placement into the pulmonary artery through the flow of blood. The balloon ...
