0959 Measures to Improve Sleep Patterns in Neonates in the Neonatal Intensive Care Unit as an Intervention to Enhance Prognosis

Key Points

The study aims to evaluate the impact of sleep-protective measures on the recovery and prognosis of neonates in the NICU.
Prospective interventional study with 35 neonates aged 26 to 38 weeks admitted to the NICU.
Implemented sleep-protective interventions including reducing ambient light and noise, scheduled maternal contact, and a specialized cradle.
Conducted polysomnographic studies before and after intervention to assess sleep–wake organization.
Post-intervention PSG showed improved organization of sleep–wake cycles across all neonates.
Recovery rates included 75% for neonatal sepsis, 91.7% for germinal matrix hemorrhage, and 86.7% for severe neurological immaturity, independently of hospitalization length.

Abstract

Abstract Introduction Background Sleep is a critical biological process for brain maturation, synaptic organization, and neurodevelopment during the neonatal period. In Neonatal Intensive Care Units (NICUs), environmental stressors such as excessive light, noise, and frequent handling disrupt physiological sleep–wake organization, potentially affecting recovery and prognosis. Despite increasing evidence linking sleep quality to neurodevelopmental outcomes, sleep-protective strategies remain insufficiently implemented in NICUs. Methods We performed a prospective interventional study including 35 neonates admitted to the NICU with gestational ages ranging from 26 to 38 weeks. Diagnoses included neonatal sepsis (n=8), germinal matrix hemorrhage (n=12), severe prematurity with marked neurological immaturity (n=15), and other associated critical conditions. All neonates underwent polysomnographic (PSG) studies adapted for neonatal age before and after implementation of sleep-protective measures, including reduction of ambient light and noise, scheduled maternal contact periods, and the use of a prototype NICU cradle designed to optimize sleep conditions. Results Post-intervention PSG demonstrated improved organization of sleep–wake cycles. By pathology: neonatal sepsis showed recovery in 6 of 8 cases (75%) with 2 deaths (25%); germinal matrix hemorrhage showed improvement in 11 of 12 neonates (91.7%) with 1 death (8.3%); severe neurological immaturity improved in 13 of 15 cases (86.7%) with 2 deaths (13.3%). Improvements were observed independently of length of hospitalization. Conclusion Targeted sleep-protective interventions in the NICU are associated with meaningful improvements in recovery and prognosis across multiple neonatal pathologies. Sleep optimization represents a low-risk, non-pharmacological strategy translating neurodevelopmental principles from bench to bedside, with potential long-term benefits for critically ill neonates.
