- Columbia University
- Brief Summary
The goal of this clinical trial is to compare sleeping in a SNOO Smart Sleeper bassinet (SNOO) with sleeping in traditional bassinet conditions in premature infants. The main questions it aims to answer are:
1. Do preterm infants who sleep in the SNOO have more quiet sleep?
2. Do preterm infants who sleep in the SNOO have improved vital signs?
* Participants will spend two separate three-hour periods sleeping in either a SNOO (which plays white noise and rocks from side-to-side) or in a SNOO that remains off (does not play white noise and does not move). There will be at least one week separating these sleep assessments.
* Participants will have their sleep stage and vital signs monitored (heart rate and oxygen levels).
* Participants will also wear two stickers on their forehead that measure brain oxygen levels (NIRS) and brain waves (EEG).
There is a chance that the infant may experience more restful sleep and improved vital signs during the 2 sleep assessments.
- Detailed Description
Sleep plays an important role in the brain growth and development of preterm infants. Neonatal sleep is made up of three stages of sleep: quiet sleep, active sleep, and transitional sleep. Poor sleep can be a result of premature birth itself as well as from simply being in the neonatal intensive care unit (NICU) environment. The interruptions that these infants are exposed to include frequent cares, physical exams, lights, and noises.
The investigators are interested in the potential positive effects on sleep of recreating the environment of the womb. The SNOO is a bassinet that uses the combination of a secure swaddle, white noise, and gentle rocking movements to mimic the conditions that infants were exposed to in the uterus before being born. The investigators are interested in studying how recreating this environment of "within the womb" impacts the sleep-wake cycles of premature infants. To do this, the investigators will measure the amount of time that premature infants spent asleep versus awake while in the SNOO through behavior observations, electroencephalogram (brain activity monitoring), and vital signs. The investigators hypothesize that sleeping in the SNOO will increase the amount of time that the premature infants spend in quiet sleep and will improve their vital signs.

Group Intervention Description SNOO group SNOO Smart Sleeper The SNOO Smart Sleeper will be used in accordance with the manufacturer's programming and instructions. Traditional bassinet group Traditional bassinet The SNOO will remain powered off to mimic the conditions of sleeping in a traditional hospital bassinet.
- Primary Outcome Measures
Name Time Method Change in amount of quiet sleep time Within one week of weaning from isolette to open crib (approximately 35-36 weeks postmenstrual age) and within one week of discharge from NICU (approximately 37-40 weeks postmenstrual age) Quiet sleep is a marker of sleep maturation and will be measured by the researcher during the 3-hour-long sleep assessments. Quiet sleep defined as eyes closed with predominantly flaccid "rag doll" appearance, body movements limited to startles, and rhythmic jaw jerks lasting 1 to 2 seconds.
- Secondary Outcome Measures
Name Time Method Change in oxygen saturation Within one week of weaning from isolette to open crib (approximately 35-36 weeks postmenstrual age) and within one week of discharge from NICU (approximately 37-40 weeks postmenstrual age) Oxygen saturation is a measure of the oxygen content of the blood, as measured by pulse oximetry.
Change in cerebral oxygenation Within one week of weaning from isolette to open crib (approximately 35-36 weeks postmenstrual age) and within one week of discharge from NICU (approximately 37-40 weeks postmenstrual age) Cerebral oxygenation is a measure of the oxygen content of brain and will be measured by near-infrared spectroscopy (NIRS).
Change in heart rate variability Within one week of weaning from isolette to open crib (approximately 35-36 weeks postmenstrual age) and within one week of discharge from NICU (approximately 37-40 weeks postmenstrual age) Heart rate variability is the fluctuation of beat-to-beat heart rate intervals over time and is a marker of autonomic nervous system maturation.
Change in intermittent hypoxemic event frequency Within one week of weaning from isolette to open crib (approximately 35-36 weeks postmenstrual age) and within one week of discharge from NICU (approximately 37-40 weeks postmenstrual age) Intermittent hypoxemic events are episodes where oxygen saturation is low for prolonged periods, as measured by pulse oximetry.
