Registro do perfil de sucção em lactentes com e sem anquiloglossia por dispositivo microcontrolado

Abstract

In the first months of life, suction is the necessary function for oral feeding (VO) and adequate oral motor development. For this, it must be coordinated and harmonic, being necessary, among other factors: reflex of search and suction; lip sealing; adequate movement of the tongue and jaw; suction rhythm, sucking hatchings alternating with pauses; coordination between suction-swallowing-breathing. The adequate movement of the tongue has the function of performing the anterior (attached around the nipple) and posterior (attached to the soft palate and pharynx), nipple compression, and the organization and propulsion of the bolus. Considering that in the literature there is no consensus on the direct relationship between ankyloglossia and difficulty in breastfeeding or early weaning, the objective of this study is to evaluate the suckling profile in infants with and without ankyloglossia through a microcontroller device. For infants with and without ankyloglossia, a sterile silicone pacifier was attached to the suction device for two minutes. The device reads pressure variations from a sensor connected to a pacifier. The pressure data were processed using Kalman filters and neural network. The results showed that infants with and without ankyloglossia, when classified with a multilayer neural network - Perceptron Multilayer, with a topology of 5, 10 and 20 neurons in the hidden layer, did not present any segregation in the classified groups, that is, it was not found difference between them, with R (0.98) indicating a strong correlation between the groups. With this, we conclude that it is not possible to relate the presence of ankyloglossia with breastfeeding difficulty, emphasizing that this study used a more objective method of evaluation when compared to other studies in the literature.
