THE EFFECT OF USING NOISE AND LIGHT REDUCTION HOOD ON OXYGEN SATURATION, HEART RATE AND SLEEP STATE OF PRETERM INFANT
Abstract
Background
It has been reported that the noisy environment significantly reduces arterial oxygen saturation, increases heart rate and disturbing the sleep state of preterm infant. It has been reported that interventions to protect the preterm infants from the noise, especially at the 34th gestational week and below, should be performed within 48 hours after delivery.
Objectives
It was determined the effect of the noise and light reduction oxygen hood on the oxygen saturation, heart rate and sleep state of the preterm infant.
Methods
The study was conducted as a randomized controlled experimental design with 80 preterm infant with 30-34 gestational weeks between April 2017 and October 2018 in the Neonatal Intensive Care Unit (NICU) in a university hospital in Istanbul. The infant’s identify form, sound meter, photo meter, actiwatch device, and monitor were collected. Ethical committee permission, institution permission and written consent from the families were obtained. In the analysis of data, descriptive statistics, independent groups t test, repeated measures test, Mann-Whitney U test, Friedman Test, Pearson chi-square test and Fisher statistics exact test were used. Statistical significance was accepted as p <0.05.
Results
There was a significant difference in oxygen saturation between the noise and light reduction oxygen hood and the standard oxygen hood (p< 0.05); no significant difference in heart rate between groups (p> 0.05) and a significant difference in sleep duration between groups (p< 0.05).
Conclusion
It was concluded that the use of noise and light reduction oxygen hood in preterm infants is an effective intervention.
