Mother's voice during feedings to help preterm babies feed better

Effect of Maternal Voice on Physiological Indicators and Feeding Performance During Full Oral Feeding Transition in Preterm Infants: A Randomized Controlled Trial

Not applicable Interventional Acibadem University · NCT07068581

This test plays a mother's voice during feedings to see if it helps preterm infants keep steadier oxygen levels, lower heart and breathing rates, and improve feeding performance.

What this trial studies

Preterm infants who are beginning the transition to full oral feeding are assigned to hear their mother's voice during the entire feeding or to receive standard feeding care, with physiological signs and feeding outcomes recorded. Primary measures include oxygen saturation, heart rate, respiratory rate, feeding maturation, and percentage of nutrient intake during feeds. Eligible infants are born at 28–34 weeks gestation, are at least 30 postmenstrual weeks and ≥1000 g, have passed a hearing screen, and whose mothers can provide expressed breast milk and speak Turkish. The intervention is delivered in the NICU at Acibadem University in Istanbul and compares continuous maternal vocal stimulation during feedings versus usual care.

Who should consider this trial

Good fit: Ideal candidates are preterm infants born at 28–34 weeks gestation who are ≥30 postmenstrual weeks old, weigh at least 1000 g, have passed hearing screening, and whose Turkish-speaking mothers can provide expressed breast milk and consent to play their voice during feedings.

Not a fit: Infants with major brain injury, congenital anomalies, severe intraventricular hemorrhage or necrotizing enterocolitis, those with hearing risk or whose mothers cannot participate, or infants outside the gestational/weight limits are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the approach could help infants stabilize physiologically and reach full oral feeding sooner, potentially shortening hospital stays and supporting development.

How similar studies have performed: Small prior studies have reported positive effects of maternal voice on physiological stability and feeding in preterm infants, but the overall high-quality evidence is limited and results have been mixed.
