Correlation of Premature Infant Sleep/Wakefulness and Noise Levels in the Presence or Absence of "Quiet Time". Adv Neonatal Care. 2018 Oct;18(5):393-399 Authors: Pugliesi RR, Campillos MS, Calado Orsi KCS, Avena MJ, Pradella-Hallinan MLC, Tsunemi MH, Avelar AFM, Pinheiro EM Abstract BACKGROUND: Peak sound levels during sleep can compromise the development of hospitalized infants. Quiet time is a strategy implemented in neonatal units to promote the sleeping of neonates by reducing noise levels, luminosity, and handling during particular periods of the day. PURPOSE: To determine the impact of quiet time on reducing sound levels and increasing total sleep time. METHODS: This longitudinal study was conducted at a neonatal intermediate care unit with a convenience sample of 12 premature infants. Four times per day, 60-minute quiet times were provided in the neonatal unit. Sleep-awake states and sound levels were evaluated during quiet times as well as 60 minutes before and afterward. Polysomnography was used for sleep-awake state assessment, and a noise dosimeter was used to check sound levels every 24 hours. RESULTS: The preterm infants had a corrected gestational age of 35.0 ± 1.5 weeks and weighed 1606.0 ± 317.8 g. Total sleep time was highest during quiet time (P = .005). Premature infants remained awake for longer following quiet times (P = .005). There was also a reduction in sound level during quiet times...
