The Effects of Pacifier-Activated Lullaby on Oral Feeding Among Preterm Infants

Résumé succinct

Preterm infants often have difficulty learning how to feed by mouth because the coordination of sucking, swallowing, and breathing develops later in pregnancy. Delays in achieving full oral feeding can prolong hospitalization and increase the need for tube feeding. This study evaluated whether a Pacifier-Activated Lullaby (PAL) system could improve oral feeding performance in preterm infants. The PAL device plays a recorded maternal or caregiver voice when an infant generates an adequate non-nutritive suck on a pacifier, providing positive reinforcement during feeding development. In this randomized controlled trial conducted at Nemours Children's Hospital in Orlando, Florida, preterm infants who were transitioning from tube feeding to oral feeding were assigned either to receive PAL therapy in addition to standard feeding care or to receive standard feeding care alone. Researchers compared measures of oral feeding performance, feeding efficiency, growth, and progression toward independent oral feeding between the two groups. The goal of the study was to determine whether reinforcing non-nutritive sucking with auditory feedback could enhance feeding development and improve clinical outcomes in preterm infants. The information gained from this study may help clinicians better understand the role of music-assisted feeding interventions in neonatal care and identify which infants are most likely to benefit from this approach.
