Hemodialysis is a medical procedure that helps remove waste products, toxins, and excess fluids from the blood when the kidneys fail to function adequately. It is one of the most common renal replacement therapies for patients suffering from chronic kidney disease (CKD) or end-stage renal disease (ESRD). During the process, a machine called a dialyzer (or artificial kidney) filters the blood through a special membrane and returns the cleaned blood back to the body.
This treatment typically takes place in a dialysis center under the supervision of a nephrology specialist. Most patients require hemodialysis three times a week, with each session lasting 3 to 5 hours, depending on individual health needs.
During hemodialysis, a patient's blood is pumped through a dialyzer. The dialyzer contains a semipermeable membrane that allows waste products and extra water to pass through while retaining necessary components like red blood cells and essential proteins. A special fluid called dialysate helps in removing unwanted substances from the blood. After filtration, the blood is returned to the body via a different pathway.
Although hemodialysis is lifesaving, it comes with some risks such as low blood pressure, cramps, infections at the vascular access site, and dietary restrictions. It’s crucial for patients to follow dietary guidelines and maintain fluid intake limits as prescribed by their nephrologist.
Plasmapheresis is a medical procedure that involves the removal, treatment, and return or exchange of blood plasma from the bloodstream. Also known as therapeutic plasma exchange (TPE), it is used to treat various autoimmune and neurological disorders where abnormal antibodies are present in the blood.
In plasmapheresis, a machine separates the plasma from the blood cells. The harmful components in the plasma, such as autoantibodies, immune complexes, or toxins, are removed. The clean plasma, or a plasma substitute like albumin or donor plasma, is then re-infused into the patient’s bloodstream.
The process is similar to dialysis. Blood is drawn through a needle and passed through a machine that separates the plasma from blood cells. The filtered plasma or replacement fluid is returned through another vein. A single session can last 1.5 to 3 hours, and the frequency depends on the condition being treated.
Potential side effects include low blood pressure, infection, allergic reactions to plasma substitutes, and bleeding problems. It is important for the procedure to be conducted in a well-equipped setting under specialist supervision.

Hemodialysis removes waste and excess fluids from the blood, mainly for kidney failure patients. Plasmapheresis targets abnormal plasma components such as autoantibodies and is used in autoimmune or immune-mediated disorders.
Each hemodialysis session typically lasts 3 to 5 hours and is performed three times a week.
Hemodialysis itself is not painful, though the needle insertion may cause minor discomfort. Some patients may feel tired afterward.
The frequency varies depending on the condition being treated. It may range from daily sessions to weekly or monthly treatments.
Yes, home hemodialysis is an option for some patients, but it requires training, equipment, and support. Not all patients are eligible for home dialysis.
Patients need to limit fluid intake and avoid high potassium, phosphorus, and sodium foods. A renal dietician can provide specific guidance.
Other alternatives include peritoneal dialysis and kidney transplantation. The choice depends on the patient's condition and medical suitability.
Yes, plasmapheresis can be safely performed in children under expert supervision, especially for pediatric autoimmune or kidney conditions.
Look for a facility with experienced nephrologists like Dr. M.V. Viswanath, modern dialysis infrastructure, infection control, emergency support, and patient care excellence—like Veda Hospital & Kidney Centre.
