While hemodialysis treatment can be efficient at replacing some lost kidney function, patients experience some complications such as blood clots, heart conditions, cardiac arrest, blood poisoning, anemia, high/low blood pressure, bone diseases, itching, sleep problems, heart inflammation, fluid overload, infections and muscle cramps.
In a hemodialysis session, a patient’s blood is diverted to a machine to remove waste products and excess fluid. A typical patient requires three dialysis sessions per week, each taking four to five hours, so even mild interactions between a patient’s blood and the dialysis membrane may lead to big problems over time.
Additional kidney failure patients are now requiring treatment as more than 30 per cent of patients hospitalized with COVID-19 develop kidney injury. Some studies in Canada showed that around 54 per cent of the Canadian patients who were hospitalized with COVID-19 developed acute kidney injury. Although the rates of acute kidney injury have fallen from the early months of the pandemic, high-risk patients should have their kidney function and fluid status monitored closely.
We can now monitor the flow at every layer of both new and existing hemodialysis membranes, which means we can assess protein deposits on the dialysis membrane surface, accumulation and blockage of the membrane pores at all points in the process.Article content
