Brief Summary

Preterm infants lack intrauterine sounds suitable for their development as they are born early. In addition, they are exposed to many unfamiliar sounds for weeks or months in the neonatal intensive care unit (NICU) where their follow-up and care are continued. , one of evidences is that the maternal voices have an effect on the physiological, neurobehavioral and autonomic functions of the preterm infants. Also, the fact that the maternal voice is a non-pharmacological and non-invasive application has importance for the preterm infant. Therefore, considering the optimal well-being of the infant, it is predicted that using the applications that simulate the extrauterine environment of the preterm infant to the intrauterine environment would decrease the stress behaviors of the infants and would provide the physiological values to be followed up in the positive direction, and as a result of these, it would contribute to supporting the recovery and shortening the discharge period. The study was planned as a randomized controlled experimental design in order to determine the effect of the sound applied on the 26-37 week-old preterm infants on their heart rate, oxygen saturation and comfort level.

Outcome Measures

Primary Outcomes (5)

  • Newborn Comfort Behavior Scale (COMFORTneo)

    The comfort scale (CS) is a scale developed by Ambuel et al., (1992) in order to assess the distress of the children taking the mechanic ventilation support and followed up in the pediatric intensive care unit. The scale was revised by Van Dijk et al. (2009) and developed only for assessing behaviors in the newborns without the physiological parameters. While the lowest score to be obtained from the scale is 6, the highest score is 30. A high score indicates that the infant does not feel comfortable and needs interventions to provide comfort and also 4-6 points indicate moderate pain and distress and 7-10 points indicate severe pain and distress. Kahraman et al., (2014) conducted the Turkish validity and reliability study of the scale with the infants of 24-42 GW.

    5 minutes

  • Heart rate

    The heart rate of the infants will measured as monitorized.

    1 minutes

  • Peripheral oxygen saturation level

    The peripheral oxygen saturation level of the infants will measured as monitorized.

    1 minutes

  • Noise level

    Noise measurement will be made with noise meter from the outside of the incubator during the hours when the study would be conducted.

    1 minutes

  • Sound level

    In order for the baby to hear the sound created in the incubator; Before each procedure, a noise measuring device was placed in the incubator and the level of sound heard by the baby in the incubator was recorded as dBA. Then the Mp3 device is set to the appropriate volume.

Study Arms (4)

Intrauterine Sound Listening Group 1

EXPERIMENTAL

This group consisted of 15 infants with 26-32,6 GW. A total of one hour of noise measurement was made inside and outside the incubator before, during and after the procedure. The babies were listened to the sound obtained in 3 time periods. If the baby is fed enterally, the feeding of the baby was completed at 10.15/13.00/16.15 before the application, the baby was placed in the prone position and the baby was rested for 30 minutes to ensure gastric emptying. Before the procedure, the baby was watched with a monitor device and recorded on video between 10.45-11.00/13.30-13.45/16.45-17.00. During the baby procedure, uterine sound was listened to the baby in the prone position monitored with a monitor device and recorded on video between 11:00-11.30/13.45-14.15/17.00-17.30 hours. After the procedure, the baby was watched with a monitor device and recorded on video between 11.30-11.45/14.15 and 14.30/17.30-17.45.

Intrauterine Sound Listening Group 2

EXPERIMENTAL

This group consisted of 15 infants with 33-36,6 GW. A total of one hour of noise measurement was made inside and outside the incubator before, during and after the procedure. The babies were listened to the sound obtained in 3 time periods. If the baby is fed enterally, the feeding of the baby was completed at 10.15/13.00/16.15 before the application, the baby was placed in the prone position and the baby was rested for 30 minutes to ensure gastric emptying. Before the procedure, the baby was watched with a monitor device and recorded on video between 10.45-11.00/13.30-13.45/16.45-17.00.
