Regarding blue dye added to enteral feedings, which statement is correct?

• A. It prevents aspiration of enteral formula
• B. Its detection is highly sensitive
• C. It is no longer recommended for detection of aspiration of enteral formula
• D. It should be added only in small amounts

Answer: (C)

Blue dye was once used to try to visualize aspiration from enteral feeds, but this practice is no longer recommended because it isn’t reliable and can cause harm. The dye isn’t highly sensitive; an aspirated amount can be missed once it’s in the airways, and colored secretions don’t consistently distinguish aspiration from other airway contents. It also doesn’t prevent aspiration, so relying on the dye gives a false sense of security. Additionally, the dye can trigger hypersensitivity reactions in some patients and may complicate interpretation of clinical findings or imaging. For these reasons, current practice favors clinical assessment, monitoring of oxygenation, imaging, and formal swallow evaluation over using blue dye to detect aspiration.
