How often should closed enteral systems be changed?

• A. Use manufacturer recommendations
• B. 24-48 hours after opening
• C. 4 hours
• D. Never

Answer: (B)

Closed enteral systems are designed to keep feed sterile, but once opened the risk of contamination begins to rise with handling and exposure. The best practice is to change the system within 24 to 48 hours after opening. This window reduces the chance of microbial contamination while avoiding unnecessary waste from changing too often. A 4-hour interval is too frequent for a closed system, and "never" is not appropriate because there is a finite period during which sterility is maintained. Always consider manufacturer directions, but the 24–48 hour guideline is the typical standard.
