The Effect of Simulated Intrauterine Sound Applied to Preterms
Condition: Neonatal Intensive Care; Preterm
MeSH terms: Premature Birth
Study type: Interventional

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.
    

Detailed description: 
      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. It is known
      that the preterm infants hear the sounds from the extrauterine and respond to these sounds
      after the 26th gestational week. The types of the sounds and the level of the noise in the
      NICU is quite different from the uterus environment. The ambient noise composed of the
      ventilators, monitors, pagers and alarms of NICU take place of the low-frequency maternal
      voices in the amniotic environment. For this reason, the preterm infants lack the normal
      audial stimulants and they are disturbed by the sounds in the NICU environment. As a result,
      the development of the auditory and language skills and the socio-emotional development of
      the infants may get harmed. The recent evidences have suggested that the auditory learning
      and voice recognition experiences of the infants are based on their prenatal experiences.
      Therefore, it is quite important to make the preterm infants listen to their mothers' voice
      and the heart rate sound which they are lack of due to their preterm birth and therefore
      keeping them away from the sounds of the NICU environment.

      In the light of this information, 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.
    

Intervention name(s): Intrauterine Sound Listening Group 1; Intrauterine Sound Listening Group 2
Intervention type(s): Other; Other
Intervention description(s): 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.; This group consisted of 15 infants with 33-36,6 GW.
