SIMBRON, Alicia V; SORBERA-FERRER, Lucas; GOMEZ DE FERRARIS, María E  e  CARRANZA, Miriam L. Cyclical pattern of non-nutritive sucking in normal and high-risk neonatos. Acta odontol. latinoam. [online]. 2013, vol.26, n.3, pp.150-154. ISSN 1852-4834.

This study determined patterns of suction cycles by recording sucking pressure in full-term infants, normal pre-term infants and newborns with pathology (hypoxia at birth). Associations between these patterns and some clinical parameters were established in order to evaluate feeding capacity for the purpose of guiding specific stimulation and aiding hospital discharge in better health conditions. Seventy-five infants of both sexes were assessed after informed consent, grouped by their status at birth. Body weight and Apgar score were determined. Sucking pressure was evaluated with an ad-hoc device. Maximum and minimum pressure scores and the number of suction cycles were measured. Data were analyzed statistically at a significance level of p<0.05. Maximum sucking pressure values varied between study groups. Full-term infants showed the highest pressure values and number of suction cycles. In pre-term infants, lower pressure values and fewer suction cycles were observed. Those with hypoxia showed great variability in both parameters. This study found a cyclical pattern of non-nutritive sucking in normal and high-risk newborns. Normal and preterm infants showed a significant direct correlation between suction cycles and Apgar scores at 5 minutes, but the infants with pathology due to hypoxia group did not show the same association. These findings are an important tool that will contribute to improving newborn maternal nutrition and optimizing the quality of life for high-risk newborns in our environment.
