Question: 1 / 400

What is a common disadvantage of high-flux dialysis?

Increased risk of clotting

Limited access for treatment

Pyrogen reactions are common

High-flux dialysis employs membranes that have a larger pore size compared to low-flux membranes, allowing for the efficient removal of larger molecules and toxins from the blood. However, one potential disadvantage associated with high-flux dialysis is the risk of pyrogen reactions, which can occur when patients are exposed to endotoxins or microbial toxins that enter the bloodstream through the dialysate or dialyzer. These reactions can lead to fever, chills, and discomfort during treatment.

Although other options may reflect concerns associated with different processes, such as clotting risks or patient comfort, they do not directly link to the inherent characteristics of high-flux dialysis as specifically as the concern regarding pyrogen reactions. Therefore, understanding the implications of high-flux dialysis on patient safety is crucial in evaluating its risks and benefits.
