Which is most likely to improve tolerance of enteral feeding in a postoperative patient with documented high GRV receiving bolus tube feedings?

• A. Holding every other feeding
• B. Putting a patient in the prone position
• C. Starting the patient on cisapride to aid with motility
• D. Placing a small bowel feeding tube for continuous feeding

Answer: (D)

High gastric residual volumes after surgery often reflect delayed gastric emptying. When feeds are given as bolus into the stomach, large volumes can accumulate, increasing distension, nausea, and risk of reflux or aspiration. Delivering nutrition beyond the stomach via a post-pyloric (small-bowel) tube in a continuous infusion bypasses the stomach, so the small intestine receives a steady, slower flow. This approach bypasses impaired gastric emptying and reduces residual volumes, making the feeds more tolerable. Holding feeds briefly reduces calories but doesn’t fix the motility issue. Prone positioning may lower aspiration risk in some situations but doesn’t address gastric emptying. A prokinetic like cisapride can improve motility but has significant safety concerns and is not routinely used. Therefore, proceeding with a small-bowel feeding tube for continuous feeding offers the most reliable improvement in tolerance in this scenario.
