Heart rate variability infant

Livio Provenzi, Sara Broso, Rosario Montirosso
Preterm infants are hospitalized in the Neonatal Intensive Care Unit (NICU) and are precociously separated from their mothers. Although developmental care interventions are meant to facilitate mother-infant bonding, physical contact is not always possible. Maternal voice exposure has been proposed as a way to foster maternal closeness and support postnatal bonding. Here we present a systematic review on maternal voice effects on preterm infants' development. Literature search occurred on 4 databases (PubMed, Scopus, Web of Science and CINAHL)...

Reduced heart rate (HR) variability in preterm infants compared with full-term infants suggests that autonomic cardiac control is developmentally delayed. However, the association between developmental changes in myocardial repolarization and gestational age remains unknown. This study investigated the association between the myocardial repolarization lability index, namely the QT variability index (QTVI) = log10 [(QTv/QTm2 )/(HRv/HRm2 )], and the perinatal profile of healthy 1-month-old infants. We included 209 infants (143 boys and 87 girls; mean gestational weeks at birth, 38...

BACKGROUND: Health outcomes are improved when newborn babies with critical congenital heart defects (CCHDs) are detected before acute cardiovascular collapse. The main screening tests used to identify these babies include prenatal ultrasonography and postnatal clinical examination; however, even though both of these methods are available, a significant proportion of babies are still missed. Routine pulse oximetry has been reported as an additional screening test that can potentially improve detection of CCHD...

Prenatal maternal immune activation (MIA) is associated with altered brain development and risk of psychiatric disorders in offspring. Translational human studies of MIA are few in number. Alterations of the salience network has been implicated in the pathogenesis of the same psychiatric disorders associated with MIA. If MIA is pathogenic, then associated abnormalities in the salience network should be detectable in neonates immediately after birth. We tested the hypothesis that 3rd trimester MIA of adolescent women who are at risk for high stress and inflammation, is associated with the strength of functional connectivity in the salience network of their neonate...

BACKGROUND: Although aberrant visual attention has been identified in infants at high familial risk for autism, the developmental emergence of atypical attention remains unclear. Integrating biological measures of attention into prospective high-risk infant studies may inform more nuanced developmental trajectories, clarifying the onset and course of atypical attention and potentially advancing early screening or treatment protocols. Heart rate-defined sustained attention (HRDSA) is a well-validated biological measure of attentional engagement that, in non-clinical infant populations, provides incremental information about attentional engagement beyond looking behaviors alone...

BACKGROUND: Continuous electronic fetal monitoring (EFM) in labour is widely used and computerised interpretation has the potential to increase its utility. OBJECTIVES: This trial aimed to find out whether or not the addition of decision support software to assist in the interpretation of the cardiotocograph (CTG) reduced the number of poor neonatal outcomes, and whether or not it was cost-effective. DESIGN: Two-arm individually randomised controlled trial...

BACKGROUND: Early-onset fetal growth restriction represents a particular dilemma in clinical management balancing the risk of iatrogenic prematurity with waiting for the fetus to gain more maturity, while being exposed to the risk of intrauterine death or the sequelae of acidosis. OBJECTIVE: The Trial of Umbilical and Fetal Flow in Europe was a European, multicenter, randomized trial aimed to determine according to which criteria delivery should be triggered in early fetal growth restriction...

Background and Aims: Although spinal anaesthesia (SA) is nowadays the preferred anaesthesia technique for caesarean section (CS), it is associated with considerable haemodynamic effects, such as maternal hypotension. This study aimed to evaluate a wide range of variables (related to parturient and anaesthesia techniques) associated with the incidence of different degrees of SA-induced hypotension during elective CS. Methods: This prospective study was conducted on 511 mother-infant pairs, in which the mother underwent elective CS under SA...

Early life stress has been shown to contribute to alterations in biobehavioral regulation. Whereas many different forms of childhood adversities have been studied in relation to cardiovascular outcomes, very little is known about potential associations between caregivers' verbally aggressive behavior and heart rate and blood pressure in the child. This prospective study examined whether maternal verbally aggressive behavior in early infancy is associated with heart rate or blood pressure at age 5-6. In the Amsterdam Born Children and their Development study, a large prospective, population-based birth cohort, maternal verbally aggressive behavior was assessed by questionnaire in the 13th week after birth...

BACKGROUND: Objective tools are needed to improve pain assessment in newborns. The aim of this study was to assess the correlation between the Newborn Infant Parasympathetic Evaluation (NIPE) index and two pain scales during a painful procedure in premature infants. METHOD: Each baby born at least at 26 weeks of gestational age (GA) undergoing a planned painful procedure in the Neonatal Intensive Care Unit (NICU) was eligible. NIPE index, heart rate variability (HRV) indices and Neonatal Acute Pain scale (DAN) were recorded across three periods: the first at rest 5 min before the painful procedure (T1), the second during it (T2), and the third 3 min after the end of it (T3)...

Infants with hypoplastic left heart syndrome (HLHS) are at high mortality especially when they are associated with bradyarrhythmias. However, the risk factor of developing high-grade atrioventricular block (HAVB) is still unclear. Seventy-three patients with HLHS in our institutions from 2002 to 2011 were enrolled. The survival rate was assessed by the anatomical types, treatments, occurrence of HAVB, severe tricuspid regurgitation (TR), and restrictive atrial septal defect (ASD) along with electrocardiogram findings at birth...

OBJECTIVE: To test the hypothesis that in neonates on mechanical ventilation, heart rate characteristics index (HRCi) can be combined with a clinical model for predicting extubation outcomes in neonates. STUDY DESIGN: HRCi and clinical data for all intended intubation-extubation events (episodes) were retrospectively analyzed between June 2014 and January 2015. Each episode started 6 hours pre-extubation or at the time of primary intubation if ventilation duration was shorter than 6 hours (baseline)...

Hypoxia-ischemia (HI) is a major contributor to preterm brain injury, but there are currently no reliable biomarkers to identify at risk infants. We tested the hypothesis that fetal heart rate (FHR) and FHR variability (FHRV) would identify evolving brain injury after HI. Fetal sheep at 0.7 of gestation were subjected to either 15 (15-min, n = 10) or 25 min (25-min, n = 17) of complete umbilical cord occlusion or sham occlusion (n = 12). FHR and four measures of FHRV (STV, LTV, SDNN, RMSSD) were assessed until 72 h after HI...

OBJECTIVES: Febrile infants younger than 3 months old present a diagnostic dilemma to the emergency physician. We aim to describe a large population of febrile infants less than 3 months old presenting to a pediatric emergency department (ED) and to assess the performance of current heart rate guidelines in the prediction of serious infections (SI). MATERIALS AND METHODS: We performed a retrospective review of febrile infants younger than 3 months old, between March 2015 and Feb 2016, in a large tertiary pediatric ED...

BACKGROUND: Dexamethasone is administered to some preterm infants with chronic lung disease to facilitate weaning from mechanical ventilation. Heart rate characteristics (HRC), including heart rate variability (HRV), may be impacted by glucocorticoids and may predict extubation readiness. A commercially available monitor developed for sepsis detection continuously calculates HRV and an HRC index, which are inversely related. OBJECTIVES: Determine the impact of dexamethasone on HRV and the HRC index, in relation to extubation success...

BACKGROUND: While biological and behavioral stress response systems are intact in early gestation, preterm infants' behaviors are often more subtle and difficult to interpret compared with full-term infants. They are also more vulnerable for regulatory issues (ie, colic) that are known to impact caregiver-infant interactions. Biobehavioral measures such as behavioral responsivity and heart rate variability (HRV), particularly cardiac vagal tone, may help elucidate preterm infants' stress/regulatory systems...
