NCT04504227

Brief Summary

This study will examine the effects of varying liquid viscosity on swallow physiology in infants with oropharyngeal dysphagia and brief resolved unexplained event (BRUE) and other children with dysphagia that would be at risk for symptoms of swallow dysfunction.

Outcome Measures

Primary Outcomes (1)

  • Swallow risk indices for thin vs mildly thick vs slightly thick liquids

    We will calculate swallow risk index (SRI) from impedance-manometry results to compare mean SRI with thin liquids and thickened liquids for subjects with aspiration compared to mean SRI for thin liquids and thickened liquids in subjects without aspiration.

    30 minutes

Secondary Outcomes (1)

  • Impedance-Manometry Swallow Physiology Metrics

    30 minutes

Study Arms (4)

Thin liquid swallows

PLACEBO COMPARATOR

Thin liquid swallows of formula or breastmilk or other liquid

Dietary Supplement: Thin liquid swallows

Slightly thick liquid swallows

Eligibility Criteria

AgeUp to 21 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Age 0 to 21 years
  • Admitted to Boston Children's Hospital after experiencing first lifetime BRUE, or with dysphagia symptoms such that they would be at risk for BRUE or other symptoms of swallowing difficulty
  • Have had videofluoroscopic swallow study performed or might have future videofluoroscopic swallow study performed.

You may not qualify if:

  • Any pre-existing medical diagnoses that exclude brief resolved unexplained event diagnosis including seizure disorders and cyanotic congenital heart disease
  • Any nasal/pharyngeal/esophageal anomalies that might affect safe placement of the pharyngeal motility catheter
  • Children fed exclusively by enteral tube
  • Allergy to rice cereal or Gelmix thickener, which will be used to adjust liquid viscosity
