In the context of critical care, hemofiltration, also known as haemofiltration, is a renal replacement treatment.
Although it is typically used to treat acute kidney damage (AKI), sepsis or multiple organ failure syndrome may also benefit from it. In hemofiltration, waste materials and water (together referred to as ultrafiltrate) are removed by convection from a patient’s blood as it travels through a system of tubes (a filtration circuit) and through a semipermeable membrane (the filter).
The blood is given back to the patient once new fluid has been added.
One moves solutes over a semi-permeable membrane by hemofiltration. However, convection, not diffusion, controls solute transport during hemofiltration.
Dialysate is not utilised when hemofiltration is employed. Instead, water and other solutes are moved from the blood compartment to the filtrate compartment, where they are emptied, by a positive hydrostatic pressure.
The flow of water caused by the hydrostatic pressure drags solutes, both tiny and big, across the membrane at a comparable pace. Convection therefore overcomes hemodialysis’s lower removal rate of bigger solutes (caused by their sluggish diffusion speed).
In hemofiltration therapy, a device called a hemofiltration machine is utilised to take the place of the kidneys in cases of acute renal failure.
Blood from the patient enters the device, which filters out waste and water before replenishing the fluid and giving it back to the patient.
The benefits of continuous venovenous hemofiltration include excellent uremic toxin clearance, hemodynamic stability, and liberal fluid control.
The Global Hemofiltration Machines market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Hemodiafiltration equipment is introduced by Safdarjung for improved dialysis. The nephrology department at Safdarjung Hospital in Delhi has developed cutting-edge dialysis technology.
Two hemodiafiltration (HDF) machines have been installed in a new area of the hospital to assist patients with improved kidney purification during dialysis.
Up till this point, only AIIMS has such equipment among government-run institutions. Safdarjung Hospital would be the second government hospital in Delhi to offer this service.
Similar to normal hemodialysis, HDF is a type of renal replacement therapy that combines diffusive and convective clearance.
More middle-molecular-weight solutes are removed by HDF than by conventional hemodialysis.
The department’s chief of nephrology declared, “Safdarjung has implemented cutting-edge equipment employing RO plants.
Hemodiafiltration is the most recent dialysis method, and it significantly improves blood purification over conventional dialysis. A patient’s quality of life will also increase.
