A dialysis catheter is a catheter catteer for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens: 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 arterial lumen typically red withdraws blood from the patient and carries it to the dialysis machine, while the venous lumen typically hemodialixis returns blood to the patient from the dialysis machine.

If a patient requires long-term dialysis therapy, a chronic dialysis catheter will be inserted. The tunnel is thought to add a barrier to infection. The most popular dialysis catheter sold on the market today is the split-tip dialysis catheter. This catheter comprises two free floating tips. The catheter is placed in one of the large veins. A common site is superior vena cava or SVC. An SVC catheter is placed by puncturing the internal jugular vein in the neck most often on the right sideand the catheter is then advanced downwards toward the chest.

Alternatively, an SVC catheter can be inserted via the subclavian veins. The femoral route is an inferior option, however, because the groin site is more prone to infection and also because the patient cannot sit upright. Some common malfunctions of dialysis catheters include clotting, infection, and kinking. One of the most common errors of tunnel hemodialysis catheter insertions is failure to locate the arterial limb of the catheter medially and the venous limb laterally.

This must be done, because most catheters have a memory in the plastic, which will cause the catheter to try to resume its natural straight form. If the arterial limb is placed laterally, this will cause the arterial inlet to float up against the vein wall, or even up against the rim of the inlet of the atrium.

This has the same effect as a vacuum cleaner hose sucking up against curtains.

This results in poor blood flows, and can force the dialysis staff to reverse flow, using the venous limb of the catheter as the arterial. This will result in more inefficient dialysis, as there will be admixing of blood from the catheter he,odialisis the same blood, over again.

A dialysis catheter must have infusion of 30cc or greater to keep the line open. IV fluids at 30cc per hr should be hung if being used for infusion.

Surgically created arteriovenous fistulas are preferred over catheters for patients with chronic renal failure, [1] as the risk of infections e. From Wikipedia, the free encyclopedia.
