Which of the following is NOT a research-based method used to restore patency to clogged feeding tubes?

• A. Cranberry juice flush
• B. Water flush
• C. Mechanical declogging devices
• D. Pancreatic enzyme mixed with sodium bicarbonate

Answer: (A)

When a feeding tube becomes clogged, you rely on methods that have been studied and shown to work. Water flushes help rehydrate the tube contents and push or loosen the blockage; mechanical declogging devices physically disrupt the clog and clear the lumen; and enzymatic approaches using pancreatic enzyme with sodium bicarbonate are used in some protocols to dissolve certain proteinaceous occlusions. Cranberry juice flush, however, does not have research backing demonstrating that it reliably restores patency. Because there’s no solid evidence supporting its effectiveness, it isn’t considered an evidence-based method for unclogging feeding tubes. In contrast, the other approaches are supported by studies and guidelines, which is why they’re used in practice.
