Detection of Infant GastrointEstinal Activity Using Sound Technology

This pilot study aims to evaluate the feasibility and safety of continuous bowel sound monitoring in healthy term newborn infants using a novel wireless acoustic monitoring system. Participants will undergo a single 4-hour recording during routine postnatal care while bowel sounds are continuously recorded using wearable abdominal sensors. Feasibility will be assessed by participant recruitment and study completion, as well as the acquisition of high-quality, analyzable acoustic data. Bowel sounds will be characterized by assessing the temporal and spectral features of bowel sounds during the early neonatal period and exploring their relationship with routine caregiving activities and feeding.

Inclusion Criteria: * ≥ 37 weeks Gestational Age (GA) Exclusion Criteria: * Congenital anomalies * Gastrointestinal abnormalities or disorders * Low birth weight (\< 2500 g) * Maternal magnesium sulfate exposure prior to delivery\* * Fragile skin or skin conditions precluding sensor placement
