Effect of Maternal Voice on Physiological Indicators and Feeding Performance During Full Oral Feeding Transition in Preterm Infants: A Randomized Controlled Trial
This study aimed to determine the effect of maternal voice on physiological indicators and oral feeding performance in preterm infants. Hypothesis 1 (H1): Preterm infants who listen to their mother's voice throughout the full oral feeding process have higher oxygen saturation levels than those who do not. Hypothesis 2 (H2): Preterm infants who listen to their mother's voice throughout the full oral feeding process have lower heart rates than those who do not. Hypothesis 3 (H3): Preterm infants exposed to maternal voice throughout the full oral feeding process have lower respiratory rates than those who are not exposed. Hypothesis 4 (H4): Preterm infants exposed to maternal voice throughout the full oral feeding process have better feeding maturation than those who are not exposed. Hypothesis 5 (H5): The percentage of nutrient intake in preterm infants exposed to maternal voice throughout the entire oral feeding process is higher than in those not exposed. Hypothesis 6 (H6): The feeding time of preterm infants exposed to the mother's voice throughout the entire oral feeding process is shorter than that of those not exposed. Hypothesis 7 (H7): The amount of food consumed per minute by preterm infants exposed to the mother's voice throughout the entire oral feeding process is greater than that of those not exposed.
• Preterm infants born at gestational age ≥28 weeks and ≤34 weeks
• Infants who are ≥30 postmenstrual weeks old at the time of enrollment
• Infants weighing ≥1000 grams at the time of enrollment
• Mothers aged 18 years or older
• Preterm infants who have passed the hearing screening test
• Infants whose mothers can provide an average of at least 30 ml of expressed breast milk daily during the study period.
• Mothers who are Turkish speakers.
• Infants for whom the decision to transition from enteral feeding to full oral feeding has been made for the first time jointly by the physician and nurse
