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 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.
Blood is aspirated from the catheter to confirm the position. Then, the free-end of the port catheter is inserted through the peel-off sheath. After the tip of the port catheter is confirmed at the aortocaval junction, the peel-off sheath is taken-off by peeling away with two hands. While peeling off, the port catheter should remain in-situ.
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.
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 ...
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible.
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.
In most uses, a catheter is a thin, flexible tube (soft catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an "indwelling catheter" (for example, a peripherally inserted central catheter). A permanently ...
