Which option describes possible causes of reflux in children receiving enteral nutrition?

• A. Rapid administration of enteral formula
• B. Delayed gastric emptying
• C. Tube migration into the esophagus
• D. All of the above

Answer: (C)

Reflux during enteral feeding is most directly linked to where the feeding tube tip is located. If the tube migrates into the esophagus, formula is delivered into a channel that isn’t designed to hold or buffer feeds the way the stomach does. The esophagus lacks the same reservoir and buffering capacity, and in children the lower esophageal sphincter is often immature, so reflux of feed upward toward the throat and potential aspiration becomes more likely. Keeping the tube correctly positioned in the stomach helps minimize this direct mechanism of reflux. Rapid administration and delayed gastric emptying can contribute to reflux in general, but they are not the primary, most direct cause when considering reflux associated with enteral tubes. The key fix is ensuring proper tube placement and monitoring tube position to prevent reflux and aspiration.
