What are the potential complications of hemodialysis?

The complications of hemodialysis are numerous and depend on which method of access is used. General complications may include nausea, fatigue and leg cramps. Long -term complications may include neuropathy, amyloidosis and aneurysm. When the kidneys stop filtering waste, the condition is called kidney failure. Without filtering the body accumulates these waste and other fluid, which can be fatal and cause other organs to stop functioning well. There are three ways to access the blood for filtering through a dialysis machine. Two lumens are connected to a separate hose. One tube draws blood from a large vein through one of the lumens that has been inserted, and the blood passes through the tube into the dialysis machine. After filtering, clean blood is sent through the other tube to the second lumen and returns to the body circulation. The complications of hemodialysis through the use of the catheter include infection and venous stenosis, which causes the veins to narrow and develop scarring.

Arteriovenous (AV) fistula is a surgical connection of the vein and artery and is a common method chosen for patients who are dependent on long -term hemodialysis. AV Fistula provides direct access to blood and bypasses the capillaries to increase blood flow. Two lines IV are inserted through the skin and fistula. One line draws the blood to be filtered, and the other line returns clean blood. Fistula hemodialysis complications include aneurysms, convulsions and tissue damage.

AV GRONTS are similar to fistulas, but Step uses artificial vessels to connect to a vein and artery. These grafts are used as an alternative to fistula, especially in patients with small or damaged veins. The hemodialysis complications by graft include blood clots and infections.

General complications of hemodialysis are often temporary. As a result of the overall process, patients may cause headache, blood pressure, nausea and fatigue. These complications often coincide with rfi cces of fluid removal. In some cases, patients may develop infections or experience an enlarged heart due to fluid overload.
