Abstract

ABSTRACT: Purpose: Compare infant suction in babies with and without ankyloglossia using a microprocessor-controlled pressure sensor coupled to a pacifier.

Methods: Fifty-five infants from 0 to 2 months of age underwent clinical examination for ankyloglossia, after which they were offered a silicone pacifier connected to the pressure acquisition

device and suction activity was recorded. Thus, we extracted the frequency of sucks within a burst, the average suck duration, the burst duration, the number of sucks per burst, the maximum amplitude of sucks per burst and the inter-burst interval.


Results: The key difference in newborns with ankyloglossia in relation to control was that they perform longer bursts of suction activity.

Conclusion: The longer burst durations are likely a compensatory strategy and may underlie the pain reported by mothers during breastfeeding. We therefore propose a method for objectively quantifying some parameters of infant suction capacity and demonstrate its use in assisting the evaluation of ankyloglossia.

Resumo

RESUMO: Objetivo: Comparar a sucção infantil em bebês com e sem anquiloglossia usando um sensor de pressão controlado por microprocessador acoplado a uma chupeta.

Método: Cinquenta e cinco lactentes de 0 a 2 meses de idade foram submetidos ao exame clínico de anquiloglossia, em seguida foi oferecido uma chupeta de silicone conectada ao dispositivo de aquisição de pressão e a atividade de sucção foi registrada. Assim, obtivemos dados sobre a frequência de sucções dentro de um período de sucções, a duração média da sucção, a duração da rajada, o número de sucções por rajada, a amplitude máxima das sucções por rajada e o intervalo entre rajadas. O teste t não pareado foi utilizado para comparações entre os grupos.

Resultados: A principal diferença dos recém-nascidos com anquiloglossia em relação aos do grupo controle é que eles realizam rajadas mais longas durante a atividade de sucção.

Conclusão: A duração mais longa das rajadas é provavelmente uma estratégia compensatória e pode estar por trás da dor relatada pelas mães durante a amamentação. Portanto, propomos um método para quantificar objetivamente alguns parâmetros da sucção infantil e demonstramos seu uso para auxiliar na avaliação da anquiloglossia.
