| description |
Stimulation with maternal odors in the immediate postnatal period is an effective strategy to achieve the continuity of the maternal ecological niche due to prematurity. In the neonate the sense of smell is fine developed, allowing the interaction of the baby with maternal biological odors, establishing a "psychobiological bridge" that could impact on the growth, development and subsequent attachment of the baby. The main goal is to evaluate physiological and behavioral responses in premature infants stimulated with maternal milk odors analyzing heart rate changes, oxygen and cerebral saturation, and hedonic response to the maternal odors. Furthermore, encourage the use of a non-invasive, ecological and low cost strategy stimulation strategy that can increase the growth and development of prematures.
Forty preterm infants under 37 weeks, and older than 72 hours of life were stimulated with distilled water and breast milk using a cotton swab for two minutes. Brain saturation was assessed using infrared spectroscopy (NIRS) and systemic saturation and heart rate with regular monitoring. Also, we use facial filming for analysis of hedonical behavioral responses, two minutes prior to stimulus (basal period), two during stimulation and two post-stimulation.
Taking the average duration of the set of facial behaviors assessed for their appetitive/aversive hedonic value at each presentation of stimulus, a significant increase (p < 0.05) is observed in behaviors considered appetitive when stimulated with milk compared to the stimulation with water. Observing facial behaviors, there is a primacy of sucking behavior over the smell of breast milk (p < 0.05) compared to the other facial behaviors evaluated. Physiologically it is observed a significant difference in brain saturation when the baby is stimulated with milk, compared to stimulation with distilled water. There are no significant differences in heart or respiratory rate. |

La estimulación con olores maternos en el período post natal inmediato es una estrategia eficaz para lograr la continuidad del nicho ecológico materno interrumpido por la prematurez. En el neonato el sentido del olfato está bien desarrollado, permitiendo la interacción del bebé con olores biológicos maternos estableciendo un “puente psicobiológico” que podría impactar en el crecimiento, desarrollo y apego posterior. Objetivo general: Evaluar respuestas fisiológicas y comportamentales en RN prematuros estimulados con olores lácteos maternos. Objetivos específicos: Analizar cambios de frecuencia cardíaca, saturación de oxígeno sistémica , saturación cerebral y respuesta hedónica. Alentar la utilización de una estrategia de estimulación no invasiva, ecológica y de bajo costo que estimule el crecimiento y desarrollo de recién nacidos prematuros. Población: Cuarenta neonatos pretérmino menores 37 semanas , y mayores de 72 horas de vida, estimulados olfativamente con agua destilada y leche materna mediante hisopo durante dos minutos. Procedimiento: La saturación cerebral se evaluó mediante espectroscopia infrarroja cercana (NIRS) y la saturación sistémica y frecuencia cardiaca con monitoreo habitual. Utilizamos filmación de la fascie para análisis de respuestas comportamentales, dos minutos previos al estímulo (basal), dos durante la estimulación y dos post-estimulación. Tomando la duración promedio del conjunto de conductas faciales evaluadas en su valor hedónico apetitivo/aversivo en cada presentación de estímulo, se observa un incremento significativo (p < 0.05) en las conductas consideradas apetitivas al ser estimulados con leche en comparación con la estimulación con agua destilada. Observando conductas, hay una primacía de la conducta de succión frente al olor de leche materna (p < 0.05) frente a las otras conductas faciales evaluadas. Fisiológicamente se observa una diferencia significativa en la saturación cerebral medida por NIRS cuando el bebé es estimulado con leche, en comparación a la estimulación con agua destilada. No se registran diferencias significativas en la frecuencia cardíaca o respiratoria Universidad Nacional Córdoba. Facultad de Ciencias Médicas.
