Oral Feeding Performance

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.

This randomized controlled study aims to evaluate the effects of kangaroo care combined with maternal voice and fetal positioning on the comfort, growth, and transition to full oral feeding in preterm infants aged 30 to 34 weeks gestation. After ethical approval, eligible infants in the neonatal clinic will be randomly assigned to either the intervention group receiving kangaroo care, maternal voice, and fetal positioning, or a control group receiving only fetal positioning in the incubator. The intervention involves daily one-hour kangaroo care sessions with maternal storytelling, followed by positioning in the lateral fetal posture, continuing at least five days per week until infants achieve full oral feeding. Infant comfort will be assessed regularly using the Neonatal Comfort Behavior Scale before feeding, immediately after kangaroo care, and after fetal positioning. Growth parameters, including weight, length, and head circumference, will be measured and recorded on kangaroo care days. The control group will receive routine fetal positioning without kangaroo care, with identical measurements taken. The study aims to determine whether kangaroo care combined with maternal voice and fetal positioning improves infant comfort, supports growth, and facilitates the transition to full oral feeding in preterm newborns.
