Hemodiafiltration is a type of treatment for getting rid of toxins and waste products from the blood with the purpose of treating kidney ailments and it is considered to be more effectual as compared to hemodialysis.
More than 20 million folks in the US are suffering from some sort of persistent kidney ailments at present, as per the Centers for Disease Control and Prevention. Kidney failure happens to be a condition when it is not possible for the kidneys to remove waste materials from the blood effectively on their own. On most occasions, it is preceded by high blood pressure and diabetes and this increases the risk of stroke or heart attack.
Why It Is Important
Even though hemodiafiltration is considered to be an effectual treatment option in Europe for kidney failures, it is only available for helping folks suffering from kidney failure in the US for a short duration of time. More water is being removed from the blood as compared to a normal dialysis therapy at the time of hemodialysis treatment along with hemodiafiltration. This procedure aids in getting rid of bigger toxic particles that are not filtered out at all times during a normal dialysis treatment. After removing the excess toxins and water, the water is replaced by the hemodiafiltration machine along with an electrolyte solution that has been purified, and the treated blood returns back to the body once again.
Hemodiafiltration is now used by some large dialysis treatment companies as an effective treatment procedure for several patients suffering from persistent kidney failure. It happens to be an effectual way of treating kidney failure, and it can also increase the patient’s lifespan. In a particular study performed at the European Dialysis and Transplantation Association, it was found by the researchers that there was a drop in the mortality rates for kidney failure patients receiving hemodiafiltration treatments by as much as 35% unlike those that did not.
According to experts, the procedure is slowly establishing itself as a ground-breaking and advanced treatment modality in dialysis. It helps to improve life expectancy significantly as well as the quality of the patients’ lifestyles.
Conventional dialysis treatments or hemodiafiltration is imperative for people suffering from kidney failure or kidney disease. However, it isn’t the only strategy employed to help dialysis patients sustain the quality of their lifestyles. Diet plays a very important role too.
How does it function?
In hemodiafiltration, similar to dialysis, one attains the movement of solutes across a semipermeable membrane. Nevertheless, it is convection rather than diffusion which controls the solute motion with hemofiltration. Dialysate is not employed with hemofiltration whatsoever. Instead, water, as well as solutes, is driven by a positive hydrostatic pressure to the filtrate compartment across the filter membrane from where it is being drained. Both large and small solutes become dragged via the membrane at an identical rate by the water flow which has become engendered by hydrostatic pressure. In this way, convection is able to overcome the minimized removal rate of bigger solutes (because of their reduced diffusion speed) observed in hemodialysis.
