Aim

    • Measure dose-response of barium materials used for dysphagia diagnosis and treatment planning.
    • Help radiologists, speech-language pathologists, and other medical professionals make informed decisions regarding safest barium materials to use during videofluoroscopic swallow studies (VFSSs).
  • Relevance
    • While modifying textures is common to prevent aspiration of food and liquids, debate surrounds unified terminology and standardized rheological properties.
method
Method
  • 16 adult males representing various medical diagnoses qualified to complete VFSSs.
    • Tested with liquid barium of three viscosities:
      • Nectar: 300 cP.
      • Thin honey: 1,500 cP.
      • Thick honey: 3,000 cP.
  • Outcome measures included:
    • Airway invasion (Penetration-Aspiration Scale).
    • Postswallow residue.
    • Patient preference.
results
Results
  • Penetration-Aspiration and residue:
    • No significant difference observed between thin and thick honey.
    • Significantly more severe airway invasion with nectar than with thin or thick honey.
    • Significantly more residue in oral cavity and valleculae with thin and thick honey than with nectar.
  • Patient preference:
    • 67% rated thin honey as “easy” or “average” to drink (vs 54% for thick honey).

Mean Penetration/Aspiration Scale (Pen/Asp) scores for liquid bariums of different viscosities. Higher scores represent more severe airway invasion.

conclusion
Conclusion
  • This study supports use of thin honey barium over thick honey barium during VFSSs.
    • The 2 honey bariums were comparable in airway protection and postswallow residue in oropharynx.
  • Thin honey was preferred by patients.
