Videofluoroscopic Analysis Of The Infant Swallow.
Published 1991 · Medicine
A better understanding of the abnormal infant swallowing mechanism requires better knowledge of the normal infant swallow. Twenty-one full-term infants under six months of age were examined using videofluoroscopy of the swallowing portion of upper gastrointestinal examinations. Components of the oral and pharyngeal stages of swallowing were evaluated. Results showed high reliability between two raters in obtaining measurement data. There was variability in suck and oral transit time, which was correlated to the number of sucks per swallow. All infants appeared to move their tongue in a "stripping" motion, and collected the material in various sites in the oral cavity or oropharynx before initiation of the swallow. The incidence of nasopharyngeal reflux was low (9.5%). The majority of infants demonstrated a slight residue in their valleculae and hesitation in the cervical esophagus. These findings indicate that videofluoroscopy provides an objective and systematic method for analyzing the infant swallowing mechanism.
