Developmental Patterns of Normal Nutritive Sucking in Infants

Abstract

SUMMARY The purpose of this investigation was to quantify normal nutritive sucking, using a microcomputer‐based instrument which replicated the infant's customary bottle‐feeding routine. 86 feeding sessions were recorded from infants ranging between 1–5 and 11‐5 months of age. Suck height, suck area and percentage of time spent sucking were unrelated to age. Volume per suck declined with age, as did intersuck interval, which corresponded to a more rapid sucking rate. This meant that volume per minute of sucking time was fairly constant. The apparatus provided an objective description of the patterns of normal nutritive sucking in infants to which abnormal sucking patterns may be compared. RÉSUMÉ Allures développementales de la succion nutritionnelle normale chez le nourrisson Le but de cette recherche a été de quantifier la succion nutritionnelle normale, utilisant un appareillage monté sur micro‐ordinateur, reproduisant les habitudes alimentation au biberon des nourrissons. 86 sessions alimentation furent enregistrées chez des nourrissons âgés de 1, 5 à 11,5 mois. L'importance de la succion, aire de succion et le pourcentage de temps passéà la succion n'est pas apparu reliéà l'âge. Le volume absorbé par succion variait avec âge, de même que intervalle entre deux succions, ce qui se traduisait par un taux de succion plus rapide. Cela signifiait que le volume absorbé par minute de succion restait sensiblement constant. L'appareillage a fourni une description objective des allures de la succion nutritionnelle normale du nourrisson, permettant une comparaison avec les succions anormales. ZUSAMMENFASSUNG Entwicklungsmuster des normalen Saugens bei Kindern Es war das Ziel dieser Arbeit, das normale Saugen mit Hilfe eines durch Mikrokomputer gesteuerten Gerätes zu quantifizieren, das die gewöhnliche Routine der Flaschenfütterung beim Kind wiedergab. 86 Fütterungen von Kindern im Alter zwischen 1–5 und 11‐5 Monaten wurden aufgenommen. Saughöhe, Saugbereich und der Zeitanteil des Saugens hatten keine Relation zum Alter. Das Volumen pro Zug nahm mit dem Alter ab, wie auch das Interval zwischen den Zügen, was zu schnellerem Saugen führte. Das bedeutet, daß das Saugvolumen pro Minute ziemlich konstant war. Das Gerät lieferte eine objektive Beschreibung der normalen Saugmuster bei Kindern, mit denen abnorme Saugmuster verglichen werden können. RESUMEN Esquemas de desarrollo de la succión nutritiva normal en lactantes El propósito de esta investigación fue el cuantificar la succión nutritiva normal, usando un instrumento basado en un microcomputador que copiaba la rutina acostumbrada del niño al alimentarse con biberón. Se registraron 86 sesiones de alimentación en niños de 1,5 a 11,5 meses de edad. El vigor de la succión, el área de succión y el porcentaje de tiempo pasado succionando no estaban en relación con la edad. El volumen de la succión declinaba con la edad, lo mismo que el intervalo entre ca da succión, lo que correspondía a una frecuencia de succión más rápida. Esto significa que el volumen por minuto de tiempo...

An automatized system for the assessment of nutritive sucking behavior in infants: A preliminary analysis on term neonates

“…This result corresponds with what we expected according to previous studies investigating the development of term newborns over the postnatal period [16]. Moreover, this trend appeared to be characteristic of infants' development also beyond the neonatal period as reported in [10].…”

“…These criteria were used to reject small fluctuations that do not correspond to suck events. We set a pressure threshold equal to -16 mmHg, and an inter-suck threshold equal to 0.3 s, according to literature values [8], [10]. The onset and the ending of a suck was detected finding out the local maximum between two consecutive sucks; however, if it was higher than zero, the zero-crossing points were taken as ending and onset of the two sucks.…”

“…In particular, sucking skills in term infants may be assessed through the measurement of Intraoral Pressure (IP) [6]- [9]. However, few studies E. Tamilia, S. Fiore, and F. Taffoni described the algorithms used to characterize the sucking signal and extract specific parameters from it [9]- [10].…”

Quantification of Intraoral Pressures During Nutritive Sucking: Methods with Normal Infants

“…Several authors have used a number of new devices and provided graphic records of both nutritive and non-nutritive sucking that are comparable to our approach [11][12][13][14][15][16][17][18][19][20]. Medoff-Cooper et al [3,6,[21][22][23][24] have used Kron's Nutritive Sucking Apparatus (KNSA) in several studies.…”
