Which intervention has NOT been proven effective in reducing the risk of aspiration in critically ill patients?

• A. Elevating head of bed to 30-45 degrees
• B. Frequent checking of GRVs
• C. Placing the distal end into the small bowel
• D. Using motility agents for high GRVs

Answer: (B)

Focusing on reducing aspiration risk means prioritizing measures that keep gastric contents from entering the airway. Elevating the head of the bed to 30-45 degrees helps prevent reflux and aspiration in many critically ill patients. Placing the distal end of the feeding tube into the small bowel (post-pyloric feeding) delivers nutrients beyond the stomach, which reduces the chance that refluxed contents are aspirated. Using prokinetic or motility agents can improve gastric emptying, lowering large gastric residual volumes and the overall risk of regurgitation. In contrast, frequent checking of gastric residual volumes has not been shown to reduce aspiration risk; it can lead to unnecessary interruptions in feeding and may not correlate with actual aspiration events. Therefore, routine GRV checks are not proven to improve outcomes in this context.
