Haemodialysis

Haemodialysis is a medical procedure used to remove waste products and excess fluid from the blood when the kidneys stop working properly. It is one of the most common treatments for kidney failure.

Overview[edit | edit source]

Haemodialysis involves diverting blood to a machine to be cleaned. Normally, the kidneys filter the blood, removing harmful waste products, excess salt, and water. In haemodialysis, a dialysis machine and a special filter called an artificial kidney, or a dialyzer, are used to clean the blood.

Procedure[edit | edit source]

To get the blood into the dialyzer, the doctor needs to make an access, or entrance, into the blood vessels. This is done with minor surgery, usually to the arm. The two main types of access are a vascular access and a peritoneal dialysis catheter.

During the procedure, the blood travels through tubes to the dialyzer, which filters out wastes, extra salt, and extra water. Then the cleaned blood flows through another set of tubes back into the body.

Risks and Complications[edit | edit source]

Like any medical procedure, haemodialysis has potential risks and complications. These can include low blood pressure, anemia, bone diseases, high blood pressure, heart disease, nerve damage, and infection. It is important to discuss these risks with your doctor before starting treatment.

Alternatives[edit | edit source]

Alternatives to haemodialysis include peritoneal dialysis and kidney transplant. Each option has its own advantages and disadvantages, and the choice of treatment should be individualized based on the patient's health condition, lifestyle, and personal preference.
