Haemodiafiltration (HDF) at Yashoda Hospital

At Yashoda Hospital, our extensive medical care for our patients goes beyond the diagnosis and treatment approaches. Our doctors and health care providers work to ensure that every patient under our care provided with the full continuum of healthcare services. We use advanced and latest technology comprises of offerings important for a faster and healthier recovery cycle.

What is Haemodiafiltration (HDF)?

A haemodiafiltration is a type of renal replacement therapy which is used to purify the blood. It works by utilising a convective-type driving force mixed with diffusional-type which is implemented in standard haemodialysis.

If we compare both the standard haemodialysis, HDF extracts more middle-molecular-weight solutes.

HDF tends to provide

• Improved clinical outcomes
• Adequate convection volumes
• Increases the clearance of larger toxins

What is Online Haemodiafiltration Technique?

HDF is much more challenging and complex than standard hemodialysis. At Yashoda hospital, we provide this latest dialysis technique. We offer online haemodiafiltration(HDF), in which the dialysis fluid is itself used as the replacement solution. In online HDF, the substitution fluid is generated by the dialysis machine, which enables large convection volumes. This is a new revolutionary technique that has benefitted out many patients suffering from kidney ailments worldwide.

Benefits of Online Haemodiafiltration

• Compared to conventional dialysis- that involves only the principle of diffusion, online HDF provides better life survival to patients.
• It has been demonstrated that any patients tolerate hemodiafiltration much better than hemodialysis with a reduced number of hypotensive episodes.
• Removal of middle molecular toxins like phosphorous, beta two microglobulins, inflammatory cytokines.
• Lesser incidence of complications like dialysis-related amyloidosis.
• Better control of renal bone disease
• Reduced pro-inflammatory cytokine levels which result in decreased cardiovascular mortality, less itching, improved nutrition, and better control of anaemia.

How Does Online Haemodiafiltration work?

Step 1: A dialysis nurse or technician places two needles in the patient’s arm from where the passes through a filter into a soft tube connected between the needle and the dialysis machine.

Step 2: The dialysis machine then pumps the blood through the filter and returns the filtered blood back into the body. During the process, the machine keeps a regular check on the patient’s blood pressure and controls

• The blood flow process in the filter
• Removes the fluid from the body

When is Online Haemodiafiltration needed?

All patients who are receiving haemodialysis are eligible to go for online HDF because there are no such contraindications. An online HDF technique enables growth toward renal replacement therapy that is most similar to the native kidney. These techniques offer a greater clearance of uremic substances with a higher range of molecular size. The online techniques provide better control of malnutrition, inflammation, anaemia, infectious complications, hyperphosphatemia, amyloidosis associated with dialysis, insomnia, irritability, restless leg syndrome, intradialytic tolerance, polyneuropathy, and itching.
