The effect of light and noise reduction on the sleep state of preterm infants

Abstract

Aim: The aim of this study was to determine the effect of reducing light and noise on the sleep of preterm infants. Material and Methods: This randomized controlled trial study was conducted on 80 preterm infants. Infants in the study group were observed under a coated oxygen hood to reduce light and noise, and the infants in the control group were observed under a standard oxygen hood, for two hours. Results: The gestational age of preterm infants in the study group was 32.92 +/- 1.17 and in the control group-33.31 +/- 0.90 weeks. There was a significant difference between the study and control groups in terms of the sleep state and activity count (p< 0.05). Discussion: It was concluded that the preterm infants slept longer and the activity count was lower by reducing the light and noise.
