Which laboratory or clinical finding may be part of PRIS?

• A. Hyperlipidemia and lipemia
• B. Hypoglycemia
• C. Hyperkalemia
• D. Hypothyroidism

Answer: (A)

Propofol Infusion Syndrome arises with prolonged, high-dose propofol infusions, and the lipid vehicle of propofol is a key factor. Because propofol is given in a lipid emulsion, continuing high-rate infusions add a substantial lipid load to the bloodstream. This frequently manifests as hyperlipidemia with lipemia, which can be detected as elevated triglycerides or visibly turbid serum on lab reports. This lipid elevation is a characteristic finding in PRIS and often accompanies other critical changes like metabolic acidosis, rhabdomyolysis, and cardiac dysfunction. Other options are less characteristic of PRIS. Hypoglycemia is not a defining feature, hyperkalemia can occur from tissue breakdown in PRIS but is not primarily due to the lipid load, and hypothyroidism is unrelated to PRIS.
