What is the preferred way to prevent feeding tube occlusion?

• A. Water is the flush of choice, with some reports suggesting pancreatic enzymes may help.
• B. Prophylactic pancreatic enzymes are always superior to water.
• C. Frequent antibiotic flushes are recommended.
• D. No flushing is necessary.

Answer: (A)

Maintaining tube patency is best achieved with regular water flushing to dilute and clear residual formula, medications, and secretions that can clog the lumen. Water is preferred because it is inert to formulas and medications and carries minimal risk, making it the standard preventive measure. There is limited evidence that pancreatic enzymes can help with occlusions, so they are not routinely used to prevent occlusion; they are not shown to be superior to water and carry potential risks. Prophylactic antibiotic flushes are not indicated for occlusion prevention and could contribute to resistance, and skipping flushing altogether markedly increases occlusion risk.
