A Clinical Trial of Pacifier Activated Lullaby (PAL) (NICU PAL)
NICU 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 NICU infants (Post-conceptional ages 34-36 weeks) in the Vanderbilt NICU. 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.

|Official Title:||A Randomized Clinical Trial of Pacifier Activated Lullaby (PAL) to Improve Feeding and Reduce Hospitalization Stay in NICU Infants|
- Suck rate and efficiency: change from pre-test (Day 0) to post-test (Day 5) [ Time Frame: Day 0, and Day 5 ] [ Designated as safety issue: No ]Feeding rate when nippling is calculated by dividing the number of cc of nippled nutrition by time for consumption. Pattern of suck bursts between pauses will be counted 10 times for each feeding on 2 occasions: day prior to the study and last day of intervention.
- Weight, height, head circumference change from Pre-test (Day 0) to Post-test, (Day 5). [ Time Frame: Day 0, and Day 5 ] [ Designated as safety issue: No ]Description: Growth : Weight, height, head circumference
- Change from Pre-test(Day 0)in Salivary cortisol levels to Post-test (Day 5) [ Time Frame: Day 0, and Day 5 ] [ Designated as safety issue: No ]Description: Stress: Salivary cortisol levels after 1 week of PAL in the intervention group
- Hospital length of stay [ Time Frame: An expected avarage of 3 weeks ] [ Designated as safety issue: No ]Description: Data on hospital stay will be recorded from the chart. The participants will be followed for the duration of the hospital stay from the time of consent for participation to the time discharge from the NICU is documented, an expected avarage of 3 weeks.
- Number of days to full oral feeds [ Time Frame: Day 0 of the study to the date of first documented full oral feed ] [ Designated as safety issue: No ]Aim: Quantify the effect of the PAL intervention on efficiency of sucking and time to reaching full oral feeds in comparison to controls. Data on the number of days from Day 0 of the study to the date of first documented full oral feed (or date of death from any cause)will be recorded from the chart.
