Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Neonatal intensive care unit infants are at high risk for oromotor difficulties including poor coordination of sucking swallowing and breathing. These feeding difficulties often result in prolonged hospitalization, with increased physiologic stressors and poor growth. In preliminary studies, Pacifier Activated Lullaby (PAL) use showed potential increased oromotor skills and decreased length of hospitalization.

The investigators propose to test the hypothesis that a week-long PAL intervention can improve feeding skills and decrease stress compared to standard of care parental interactions in infants in the late preterm period. The investigators also hypothesize that these improvements will result in shorter hospital stays and increased growth in the intervention group.

Our study design is a prospective randomized controlled trial design of 94 infants (Post-conceptional ages 34-36 weeks). The 47 intervention-group infant/mother dads will receive a book library with one lullaby book and record her voice to the PAL, which the music therapist will then administer in 15-minute sessions for 5 consecutive days. The 47 participants in the control group will receive the same library but no recording will be made or PAL used. Outcomes measured will include time to full oral feeds, suck rate and efficiency, salivary cortisol levels before and after intervention, daily growth parameters and nutritional data, and hospital length of stay.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objectives: We conducted a randomized trial to test the hypothesis that the mother's voice played through a pacifier-activated music (PAM) player during nonnutritive sucking would improve the development of sucking ability and promote more effective oral feeding in preterm infants.

Methods: Preterm infants between 34 0/7 and 35 6/7 weeks postmenstrual age, including those with brain injury, who were taking at least half their feedings enterally and less than half orally, were randomly assigned to receive 5 daily 15-minute sessions of either PAM with mother's recorded voice or no PAM, along with routine nonnutritive sucking and maternal care in both groups. Assignment was masked to the clinical team.
