A Bradycardia-Based Stress Calculator for the Neonatal Intensive Care Unit: A Multisystem Approach.

ABSTRACT: Early life stress in the neonatal intensive care unit (NICU) can predispose premature infants to adverse health outcomes and neurodevelopment delays. Hands-on-care and procedural pain might induce apneas, hypoxic events, and sleep-wake disturbances, which can ultimately impact maturation, but a data-driven method based on physiological fingerprints to quantify early-life stress does not exist. This study aims to provide an automatic stress detector by investigating the relationship between bradycardias, hypoxic events and perinatal stress in NICU patients. EEG, ECG, and SpO 2 were recorded from 136 patients for at least 3 h in three different monitoring groups. In these subjects, the stress burden was assessed using the Leuven Pain Scale. Different subspace linear discriminant analysis models were designed to detect the presence or the absence of stress based on information in each bradycardic spell. The classification shows an area under the curve in the range [0.80-0.96] and a kappa score in the range [0.41-0.80]. The results suggest that stress seems to increase SpO 2 desaturations and EEG regularity as well as the interaction between the cardiovascular and neurological system. It might be possible that stress load enhances the reaction to respiratory abnormalities, which could ultimately impact the neurological and behavioral development.

Project description:Background Preterm birth and admission to the neonatal intensive care unit (NICU) could induce post-traumatic stress disorder (PTSD). PTSD is an important factor to focus on, as it is associated with parental mental health difficulties and with changes in caregiving quality such as increased intrusiveness, reduced sensitivity, and increased attachment insecurity for the child. Aims We aimed to study the main risk factors, in the early life of newborns, and preventive measures for PTSD in parents of neonates hospitalized in the NICU. Methods We included parents of preterm newborns, consecutively admitted to the NICU of the University La Sapienza of Rome. The presence of PTSD following preterm birth and NICU admission was assessed using the Clinician-administered PTSD scale (CAPS) at enrollment and at 28–30 days following NICU admission or the moment of discharge. We also evaluated the Family Environment Scale which measures the social environment of all types of families; the Parental Stressor Scale which measures parental anxiety and stress; the Spielberger State-Trait Anxiety Inventory consisting of two parts measuring the State (response to present situation) and Trait (pre-disposition to be anxious) anxieties separately, and the Beck Depression Inventory Second Edition assessing depressive symptoms. Results We found, in a multivariate analysis, that the gestational age of newborns admitted to NICU significantly (β = 2.678; p = 0.040) influences the occurrence of PTSD. We found that the cases showed significantly (β = 2.443; p = 0.020) more pathological Parental Stressor Scale sights and sounds scores compared to controls. The early Kangaroo-Care (KC) significantly (β = −2.619; p = 0.015) reduces the occurrence of PTSD. Conclusion Post-traumatic stress disorder in parents of preterm newborns is a pathological condition that should be properly managed, in the very first days after birth. The NICU environment represents a main risk factor for PTSD, whereas KC has been demonstrated to have a protective role in the occurrence of PTSD.
