What is a subclavian catheter?

What is a subclavian catheter?

Central catheters provide dependable intravenous access and enable hemodynamic monitoring and blood sampling [1-3]. The subclavian veins are an often favored site for central venous access, including tunneled catheters and subcutaneous ports for chemotherapy, prolonged antimicrobial therapy, and parenteral nutrition.

Why subclavian vein is used for catheterization?

Subclavian catheterization also carries a lower risk of catheter-related infection and thrombosis than femoral or internal jugular vein catheterization. Since Aubaniac’s original description in 1952,4 subclavian vein catheterization via the infraclavicular approach has become a well-established technique.

What is subclavian IV?

Percutaneous cannulation of the subclavian vein uses anatomic landmarks to guide venipuncture and a Seldinger technique to thread a central venous catheter through the subclavian vein and into the superior vena cava.

Is subclavian vein central or peripheral?

ACCESS SITE Centrally inserted central venous catheters are primarily placed via the internal jugular vein, subclavian vein, or femoral vein. Alternative insertion sites include the external jugular vein, cephalic vein, and proximal great saphenous vein.

Where is the subclavian vein?

The subclavian vein is a paired large vein, one on either side of the body, and runs under the clavicle and anterior to the artery of the same name. The diameter is approximately to that of the little finger.

Why do we Cannulate the right subclavian vein?

Right subclavian cannulation, versus left, is sometimes preferred because it avoids the thoracic duct and because the right pleural apex is lower than the left.

Where is the subclavian located?

The subclavian arteries lie just below the clavicles, providing blood supply to the bilateral upper extremities with contributions to the head and neck. The right subclavian artery derives from the brachiocephalic trunk, while the left subclavian artery originates directly from the aortic arch.

What is a subclavian triple lumen catheter?

Triple-lumen catheter The most commonly used catheter for central venous access is the triple lumen catheter. They are preferred (particularly in the ICU) for their three infusion channels that allow for multiple therapies to be administered simultaneously.

Is subclavian vein a deep vein?

The subclavian vein (SVC) is classified as a deep vein and is the major venous channel that drains the upper extremities. Other deep veins of the upper extremity that accompany the major arteries include the radial, ulnar, brachial, axillary veins.

How do you Cannulate subclavian veins?

A syringe is placed on gentle suction while attempting to cannulate the vein. The thumb is used to help guide the needle below the clavicle between the clavicle and the first rib. It is important to guide the needle along a linear path and avoid a steep angle of the needle related to the clavicle.

Is the subclavian a vein or artery?

The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart….
