Step of protocolReason
1. Review of indications, contraindications, education of the patient and the family, review of transportation and positioning logisticsSuspected oropharyngeal dysphagia +/- need to examine anatomy and physiology of oral and pharyngeal regions during deglutition +/- need to define treatment strategies to improve or compensate for the dysphagia if identified.
2. Baseline view of anatomyAssess and identify anatomic structures prior to introduction of contrast
3. Lateral view firstBest able to detect aspiration
4. Sequence of pathophysiologies listedView swallowing from front (lips) to back (posterior pharynx) and UES
5. Begin with 3-mL thin liquid bariumThin liquid may reveal airway protection issue sooner, and thus aspiration risk; swallow stages more discrete; small amount less likely to compromise respiratory status
6. Continue with second 3-mL thin liquid swallowInitial swallow may be more of a calibration swallow and second swallow of same condition may be more representative
7. Increase volume to 5 mLWatch for change in physiology with increase volume
8. Increase volume to cup drink (unregulated) telling patient to "take a drink like you are thirsty."This is both a challenge to the mechanism but also perhaps a more representative type of swallow done when meal is served
9. Return to 5-mL amount and examine increased texture of thick liquid (nectar)Observe for any change in physiology, or tolerance with increased texture cohesion; look for any increased residue with consistency as increased residue could increase aspiration risk
10. Give puree condition 5 mLPuree condition may reveal further weakness and residue or possibly oral stage disorganization more apparently
11. Give solid condition (one quarter of a graham cracker cookie coated with the puree contrast from earlier administrationAllows assessment of chewing patterns and organization orally as well as pharyngeal clearance and potential choking/asphyxia risks
12. An earlier swallow may be repeated at any time or a trial treatment strategy or maneuver may be attempted; pills may also be given if study unrevealing to this pointSeek to test hypotheses regarding treatment strategies or to remember that oropharyngeal and esophageal stage dysfunctions may coexist or esophageal dysfunction may masquerade as oropharyngeal symptomatology
13. Record swallow timing events for transit and swallow responseAssists in judgments regarding normality of swallow event timing
14. Turn patient to view anteroposterior view of swallowingLook at swallow symmetry of bolus transit and determine any weakness asymmetry
15. Our study concludes with viewing the patients laryngeal complex and vocal cords during production of a series of vowel /a-a-a/Look for any trace penetration in laryngeal vestibule and assess the symmetry and efficiency of true vocal cord movements
16. Score degree of penetration/aspiration using standardized rating scaleDegree of penetration/aspiration assessed with each condition may provide information about improved performance during the study while suggesting patients risk level for developing pneumonia
17. Combine VFSS observations to interpret overall severity ratingThis may suggest possible management or allow for comparison of severity following a treatment program or at a later date of reassessment
