简要总结
Preterm infants in the Neonatal Intensive Care Unit (NICU) face environmental and clinical stressors that may affect physiological stability and development. This pilot randomized crossover study tests Personalized Music Therapy (PMT) based on recorded parental voices versus Quiet Rest. Outcomes include tissue oxygenation index (TOI) via near-infrared spectroscopy (NIRS) and heart rate (HR), respiratory rate (RR), and oxygen saturation (SpO2). Each infant completes two Periods (PMT and Quiet Rest) in randomized order, separated by a 2-day washout. Parental stress is measured at discharge using the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS:NICU). Findings inform feasibility, variance estimates, and protocol refinements for a larger trial.
详细描述
Background and rationale. Preterm infants in the Neonatal Intensive Care Unit (NICU) are exposed to noise, light, and frequent handling, which can affect physiology and development and increase parental distress. Family-centered music therapy using the parental voice is a low-risk intervention that may modulate cerebral oxygenation and autonomic parameters during exposure. Neonatal NIRS studies report small-to-moderate average changes in cerebral oxygenation with parental voice or music and heterogeneous individual responses, supporting standardized procedures and within-participant designs (van Bel 2008; Alderliesten 2016; Meder 2021; Yue 2021).
Ethics and consent. Enrollment proceeds under Ethics Committee approval on file; written informed consent is obtained from the parent(s) or legal guardian(s) per local policy. Consent from both parents is sought when applicable; a single signature is acceptable in single-parent or court-sanctioned guardianship cases according to site policy.
Design. Single-center, randomized 2 by 2 crossover pilot. Infants are randomized to Sequence AB (Period 1 = PMT, washout 2 days, Period 2 = Quiet Rest) or Sequence BA (Period 1 = Quiet Rest, washout 2 days, Period 2 = PMT).
Pre-intervention voice preparation (outside study periods). A trained music therapist records the parent's singing or voice and performs basic audio processing (smoothing peaks, removing artifacts, setting a target intensity). The audio files are stored securely for audio playback during PMT. No outcomes are collected during preparation.
Conduct of each period (50 minutes, 8:00 to 9:00 PM local time, low-stimulation NICU room). A bedside speaker is positioned approximately 30 cm from the infant's head; audio playback is set to approximately 45 dBA (plus or minus 3) at the infant's ear level. Each period follows the same structure:
