P0283 / #969: RHEOLOGICAL ANALYSIS OF LIQUIDS OFFERED IN VIDEOFLUOROSCOPY EXAM TO NEONATES AND INFANTS: A PRELIMINARY STUDY

Abstract

Aims & Objectives: Objective The propose of this exploratory study was to know the behavior and macroscopic properties of untreated breast milk and infant formula, isolatedly and with barium sulfate added, providing information that can help speech-therapists and radiologists during the videofluoroscopy swallowing studies (VFSS). Methods: Method Rheological measurements were taken in an R/S+ Rheometer SST, SN 7023123, with a sample of regular infant formula; a sample of untreated breast milk; both isolated and with barium sulfate added, in the proportion of 2:1, respectively. Results: Results The breast milk and the infant formula have presented the adjusted viscosity similar between them, considered as thin liquid, according to the National Dysphagia Diet (NDD) classification (1.73 ± 0.12 cP and 1.53 ± 0.06 cP, respectively). The addition of barium in the proportions used in this study increased the viscosities of untreated breast milk 18 times, from 1.73 ± 0.12 cP to 31.30 ± 0.32 cP, and of the formula 25 times, from 1.53 ± 0.06 to 38.31 ± 2.19 cP, reaching thresholds close to that of nectar. Conclusions: Conclusion The results indicated confirm the need of knowledge and care in preparing liquids to be offered in pediatric VFSS, especially with neonates and infants. The use of liquids in consistency and viscosity as close as possible to what will be proposed in the indication of the patient’s diet is fundamental for their safety, thus contributing for clinical decision-making and speech-language practice. This will guarantee more confidence that VFSS represents the infant swallow function, minimizing risks on their treatment.
