Does parenteral nutrition solution require refrigeration?

Does parenteral nutrition solution require refrigeration?

• A. Yes
• B. No
• C. Only after opening
• D. Only if temperature exceeds 25°C

Answer: (A)

Storage temperature is crucial for parenteral nutrition because these solutions are complex, sterile mixtures that can support microbial growth and undergo chemical changes if kept warm. Refrigeration slows bacterial proliferation and protects the stability of components like amino acids, dextrose, and lipid emulsions, helping preserve safety and potency from manufacture through administration. When it’s time to use them, they are typically brought to room temperature briefly for infusion, but they should not be kept at room temperature for extended periods. The standard practice is to keep PN solutions refrigerated (2–8°C) until ready to use, with defined hang times that depend on the product and institutional guidelines. Therefore, refrigeration is required.
