Objective: To define the acoustic parameters and the feasibility of using swallowing acoustic analysis as an auxiliary method for the transition from nasogastric or orogastric tube feeding to oral breastfeeding. Methodology: A cross-sectional study, which consisted of the following steps: 1. Data collection: Thirty-two newborns participated in this study (16 preterm and 16 full-term); 2. Clinical speech-language pathology evaluation: Clinical data were collected using Sonar Doppler used to assess the readiness of preterm infants to start oral feeding and swallowing sounds. Swallowing sounds were captured during breastfeeding and analyzed according to the frequency, intensity, and time of swallowing, as well as the pause time between swallows and the number of swallows. Results: The control and study groups presented significant differences in the mean wave time and swallowing per minute variables. Conclusion: Sonar Doppler, as an instrument used to capture sounds, is a viable auxiliary resource to evaluate the transition from nasogastric or orogastric tube to oral breastfeeding.

“…La evaluación de la deglución se llevó a cabo con el Sonar doppler de marca AngelSounds -JPD-100S mini, que transmite la onda de ultrasonido a través de un piso eléctrico cerámico con una frecuencia de ultrasonido 3.0 MHz, potencia de ultrasonidos < 10mW / cm2, intensidad acústica < 10 mW / c, presión negativa máxima < 1 Mpa, intensidad del haz de salida < 20mW / c, dimensión 104,5 x 50 x 70 mm, y peso 69,5 g. La onda acústica fue analizada mediante el software DeglutiSom, que es una herramienta utilizada en la evaluación, monitorización y rehabilitación de las dificultades de la deglución (Lemos et al, 2020) Se utilizó el software DeglutiSom®, desarrollado por Engefono en 2014 y validado en 2021 (Enz, Vaz, Nunes, Rosa, Marques, et al, 2022;García y Henao,2022).…”

Con el avance de la tecnología se crean mecanismos que facilitan y optimizan el proceso de evaluación de los parámetros acústicos de la deglución, pero es necesario que la medición sea confiable, considerando los patrones de normalidad. El objetivo de este estudio fue determinar los parámetros acústicos de frecuencia, intensidad y duración de la deglución con el sonar doppler y software Deglutisom en población adulta en Popayán. La metodología fue cuantitativa descriptiva y transversal. Se evaluó la deglución a 115 adultos y 31 adultos mayores, sujetos normotípicos seleccionados de manera no aleatoria, con la ingesta de tres consistencias: fluidos propios, líquido claro y pastoso. Se observó que para el grupo de “adultos” los valores promedio (x̄) de los parámetros que indicaron estar dentro de normalidad fueron: en frecuencia entre 760,44 Hz a 766,92 Hz, la intensidad osciló entre 99,99 a 100 dB; y en la duración entre 0,90 a 0,97 segundos. En los “adultos mayores” los valores de normalidad en el parámetro de frecuencia estuvieron entre 765,93 a 763,41 Hz, la intensidad entre 99,64 a 100 dB y la duración sobre ̄1,01 a 1,11 segundos en las tres consistencias. Los parámetros acústicos son similares entre los mismos grupos de “adultos” y adulto mayor; pero, si se presentaron diferencias significativas al compararlos entre ellos, especialmente en el parámetro de duración (seg) (p<0,05). Se concluye que se logró establecer los parámetros acústicos de intensidad, frecuencia y duración y se observaron algunos cambios asociados a la edad y consistencia de los alimentos.

“…The operating system used was Windows 7®. The DeglutiSom® software, developed by Engefono in 2014, and validated in 2021 (Enz et al, 2021), was used to record the acoustic signals and later analyze them (Figure 1). For the process of capturing swallowing sounds, subjects were instructed to remain seated in a chair, with the cervical region in ventral flexion (simulating a normal meal position) and with free access to the neck.…”

Objective: To measure the accuracy of DeglutiSom as an auxiliary method to assess swallowing in patients with Parkinson's disease (PD). Methodology: Accuracy study. Among 248 individuals, 91 participants met the inclusion criteria, with a mean age of 64.9 years (SD 7.7), 53.8% male and 46.2% female, with a mean disease duration of 12.6 years (SD 3.8 years). Two instrumental studies were performed: An acoustic analysis with Sonar Doppler via the DeglutiSom Software, and a videofluoroscopic swallow study. Three judges analyzed the swallowing sounds in the DeglutiSom software and the instrumental examination findings. Results: The inter-rater reliability was 90.1%, with 4.4% degree of partial agreement and 5.5% disagreement. Sensitivity resulted in 90.0% and specificity in 90.0%. A sensitivity of 97.0% and specificity of 91.0% are indicators of a high validity for the dysphagia screening method, with predictive value (+) of 97.0% and predictive value (-) of 91.0%, with an accuracy method of 96.0%. The validity indicator values for screening aspiration were also high, with a sensitivity of 90.0%, specificity of 90.0%, predictive value (+) of 82.0%, predictive value (-) of 95% , 0% and 90.0% accuracy. Conclusion: The method proposed is considered appropriate for oropharyngeal dysphagia and tracheal aspiration screening in patients with Parkinson's Disease.
