Which condition is a known risk for patients receiving their first dialysis treatment?

• A. Infectious complications
• B. Dialysis disequilibrium syndrome
• C. Hypotension during treatment
• D. Hyperkalemia during setup

Answer: (B)

Dialysis disequilibrium syndrome occurs when rapid removal of solutes, especially urea, during dialysis creates an osmotic difference between the blood and brain. On the first treatment, the brain hasn’t had time to adapt to the changing osmolality, so the quick drop in plasma osmolality pulls water into brain tissue, causing cerebral edema. This can lead to headache, nausea, confusion, and in severe cases seizures or coma. Because this neurologic complication is most likely to occur during the initial dialysis sessions when solute removal is most abrupt, it’s the best answer for a question about risks specific to a first dialysis treatment. Infectious complications can happen with dialysis access but aren’t unique to the first session; hypotension during treatment is a common dialysis issue but not unique to the initial treatment; hyperkalemia during setup reflects pre-dialysis potassium status rather than a session-related risk tied to being new to dialysis.
