The Effect of Sleeping Environment on Sleep-Wake Organization in Preterm Infants

Columbia University·interventional·Posted Feb 3, 2023·Updated Sep 15, 2025

In Brief

A clinical study evaluating SNOO Smart Sleeper and Traditional bassinet for Prematurity and Very Preterm Maturity of Infant. Completed, enrolled 20 participants across 1 site.

Detailed 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.

Interventions

SNOO Smart Sleeperdevice

Infants will be secured in the SNOO Sleep Sack. They will be placed in the center of the SNOO Smart Sleeper. The SNOO will be powered on and will start playing white noise and rocking from side-to-side. The SNOO's movement and sound settings will automatically ramp up and down as needed in response to the infant's sensed level of fussiness or crying per the manufacturer's programming. The "preemie mode" will be enabled, which caps motion at level 2 out of 5.

Traditional bassinetdevice

Infants will be swaddled using a standard hospital blanket. They will be placed in the center of the SNOO Smart Sleeper, but the SNOO will be left powered-off. No white noise will be played. No side-to-side rocking motions will occur.
