The Influence of Side-Lying Position on Oropharyngeal Swallow Function in At-Risk Infants: An Exploratory Study

This investigation assessed the effect of side-lying position on infant oropharyngeal swallow physiology. Infant modified barium swallow studies (MBS) recordings were retrospectively examined in matched-pairs comparing at-risk infants swallowing in both an upright/cradled position and a side-lying position. Swallow parameters were measured independently and through a consensus coding approach. Infants fed in side-lying position showed a decrease in airway invasion severity as compared with when those same infants were fed in an upright/cradled position (P = .009). Bolus location at the time of swallow initiation was higher when infants were fed in side-lying position as compared with cradle position (P = .024), representing decreased risk of airway invasion. Infants fed in side-lying position demonstrated fewer swallows per breaths (P = .032). This pilot study validates the need for additional research to further define the mechanisms related to this improvement, and to determine how diagnosis and medical stability moderate these findings.

A Multidisciplinary Approach to Infants With GERD-Like Symptoms: A New Paradigm

OBJECTIVES

Infants with gastroesophageal reflux disease (GERD)-like symptoms have been classically defined as having a wide array of symptoms. In these instances, anti-reflux medications are ineffective and overprescribed. Rather these symptoms are more attributable to dysphagia and unsettledness/colic. To address these conditions at our center, both speech language pathologist (SLP) and/or occupational therapist (OT) have contributed to evaluation. We hypothesized that dysphagia and unsettledness/colic are highly prevalent, yet under recognized in this population.

METHODS

Full-term infants with typical development and under 6 months of age (N = 174) were included. Infants with suspected dysphagia and/or evident colic/unsettledness were evaluated by SLP and OT, respectively.

RESULTS

GERD-like symptoms were present in 109 infants with attributes of dysphagia in n = 46, unsettledness/colic in n = 37, and combined in n = 26.

CONCLUSION

A multidisciplinary approach, including SLP and OT, is recommended for the evaluation of infants with GERD-like symptoms.

Non-Pharmacological and Non-Surgical Feeding Interventions for Hospitalized Infants with Pediatric Feeding Disorder: A Scoping Review

Infants born prematurely or with complex medical conditions often require treatment to facilitate safe and efficient feeding. Practice is based on evidence, so frontline clinicians look to the literature to make informed clinical decisions. The aim of this scoping review was to map and describe the literature base for infant feeding and swallowing interventions and to identify areas for further research. Four electronic databases were searched from the sources' inceptions through April 2020 using a search strategy designed by a health sciences research librarian. Thirteen grey literature sources were searched and forward and backward citation chasing was performed. Inclusion criteria were English-language studies reporting non-pharmacological and non-surgical interventions for hospitalized infants. Exclusion criteria included interventions exclusively for infants with cleft lip or palate or for infants being fed exclusively though enteral feeding. Data were extracted using a form created a priori and data were reported descriptively. We reviewed 6654 abstracts: 725 were chosen for full-text review and 136 met inclusion. Most studies explored interventions for infants born prematurely (n = 128). Studies were stratified by intervention domain: bridging (n = 91) and feeding/swallowing (n = 45); intervention approach: direct (n = 72), indirect (n = 31), or combination (n = 33); and outcome: feeding performance (n = 125), physiologic stability (n = 40), and swallowing physiology (n = 12). The body of research in infant feeding has grown; however, a need remains for research focused on populations of infants with various medical complexities and for frequently used interventions that lack supporting evidence.
