A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...
Central venous catheters (CVC) are catheters inserted into the large veins of the arm, neck, chest, or groin. CVC's are used for delivery of medications, nutrients, or blood products for a longer periods, usually weeks to months. [1] There are several reasons for the use of central venous access: [2] To get more than one drug at a time
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.
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.
In some situations, venous access is obtained by inserting catheters into the large central veins of the trunk of the body such as the internal jugular, subclavian, or femoral veins. This type of venous access is performed with central venous catheters (CVCs) , and is required in certain situations where peripheral access is inadequate.
The Seldinger technique is used for angiography, insertion of chest drains and central venous catheters, insertion of PEG tubes using the push technique, insertion of the leads for an artificial pacemaker or implantable cardioverter-defibrillator, and numerous other interventional medical procedures.
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.
The Trendelenburg position is also used when placing a central venous catheter in the internal jugular or subclavian vein. The Trendelenburg position uses gravity to assist in the filling and distension of the upper central veins, as well as the external jugular vein. It plays no role in the placement of a femoral central venous catheter. [7]
