How often should feeding tubes be flushed with water in continuous infusion enteral feeding?

In continuous infusion enteral feeding, feeding tubes should be flushed with water every four hours to ensure proper tube patency and to prevent clogging. Regular flushing is essential as it helps maintain the flow of the enteral formula while also providing hydration. Flushing with water removes any residual formula that may adhere to the tube's inner surfaces and minimizes the risk of bacterial growth, which can lead to complications such as infections or tube obstructions.

The practice of flushing every four hours is widely recommended in clinical guidelines as it balances the need for tube maintenance without excessive fluid administration, which could contribute to fluid overload, particularly in patients who may be at risk. This recommended interval supports optimal nutritional delivery and patient safety.
