We are having a discussion on what to use to flush enteral feeding.
1. The question on the table is for neonates at what age can we start using purified water to flush enteral tubes?
2. Is the age actual or gestational age?
3. What is the reason that neonates need sterile water for flush and cannot use purified water?
4. Are we worried about hyponatremia when using sterile water in neonates/peds?
4. If you have any policies or studies that you can share with me for flushing enteral feeding in neonates and pediatrics, please.

Thank You.
