Continuous monitoring of electroencephalography (EEG), with a focus on amplitude-integrated EEG (aEEG), has been used in neonatal intensive care for decades. A number of systems have been suggested for describing and quantifying aEEG patterns. Extensive full-montage EEG monitoring is used in specialised intensive care units. The American Clinical Neurophysiology Society published recommendations for defining and reporting EEG findings in critically ill adults and infants. Swedish neonatologists and clinical neurophysiologists collaborated to optimise simplified neonatal continuous aEEG and EEG recordings based on these American documents...

To improve the prediction of neurodevelopmental outcome in very preterm infants, this study used the combination of amplitude-integrated electroencephalography (aEEG) within the first 72 h of life and cranial magnetic resonance imaging (MRI) at term equivalent age. A single-center cohort of 38 infants born before 32 weeks of gestation was subjected to both investigations. Structural measurements were performed on MRI. Multiple regression analysis was used to identify independent factors including functional and structural brain measurements associated with outcome at a corrected age of 24 months...

OBJECTIVES: Hypothermia (HT) improves the outcome of neonatal hypoxic-ischemic encephalopathy. Here, we investigated changes during HT in cortical electrical activity using amplitude-integrated electroencephalography (aEEG) and in cerebral blood volume (CBV) and cerebral hemoglobin oxygen saturation using near-infrared time-resolved spectroscopy (TRS) and compared the results with those obtained during normothermia (NT) after a hypoxic-ischemic (HI) insult in a piglet model of asphyxia...

OBJECTIVE: To determine whether monitoring cerebral oxygen tissue saturation (StO2 ) with near-infrared spectroscopy (NIRS) and brain activity with amplitude-integrated electroencephalography (aEEG) can predict infants at risk for intraventricular hemorrhage (IVH) and death in the first 72 hours of life. STUDY DESIGN: A NIRS sensor and electroencephalography leads were placed on 127 newborns <32 weeks of gestational age at birth. Ten minutes of continuous NIRS and aEEG along with heart rate, peripheral arterial oxygen saturation, fraction of inspired oxygen, and mean airway pressure measurements were obtained in the delivery room...

BACKGROUND AND AIM: Caffeine improves neurodevelopmental outcome of preterm infants. This study analyses the effects of caffeine on the neonatal brain. We hypothesized that caffeine has a neuroprotective effect through an increase in oxygen metabolism; reflected by increased cerebral oxygen extraction, electrical function, and perfusion. METHODS: Preterm infants <32 weeks gestation (GA) receiving their primary dose caffeine-base (10 mg/kg) were included. Ten minutes of stable monitoring were selected before, during, and every hour up to 6 h after caffeine...

BACKGROUND: Term equivalent age (TEA) brain MRI identifies preterm infants at risk for adverse neurodevelopmental outcomes. But some infants may experience neurodevelopmental impairments even in the absence of neuroimaging abnormalities. OBJECTIVE: Evaluate the association of TEA amplitude-integrated EEG (aEEG) measures with neurodevelopmental outcomes at 24-36 months corrected age. METHODS: We performed aEEG recordings and brain MRI at TEA (mean post-menstrual age of 39 (±2) weeks in a cohort of 60 preterm infants born at a mean gestational age of 26 (±2) weeks...

REVIEW
Lena Hellström-Westas
The amplitude-integrated electroencephalogram (aEEG) is a filtered and compressed EEG trend that can be used for long-term monitoring of brain function in patients of all ages. aEEG is increasingly used in neonatal intensive care units since several studies have shown its utility in high-risk newborn infants. Main indications for aEEG monitoring include early evaluation of brain function after perinatal asphyxia and seizure detection. The aEEG is usually recorded from one or two channels derived from parietal, central, or frontal leads...

BACKGROUND: Amplitude-integrated electroencephalography (aEEG) is used increasingly in neonatal intensive care and seems helpful in predicting outcomes at the age of 2 years. OBJECTIVES: To determine whether early aEEG patterns in preterm infants are equally useful in predicting outcomes at early school age. METHODS: We recorded aEEG in 41 preterms (gestational age 26.0-32.9 weeks) at a median postnatal age of 9.7 h (IQR 7.0-25.3) and in 43 preterms on median day 8 (IQR 7-9)...

BACKGROUND: It has been suggested that mild hypothermia treatment of hypoxia-ischemic encephalopathy (HIE) should start within 6 h after HIE, but many children are admitted to the hospital > 6 h, particularly in developing areas. We aimed to determine whether hypothermia treatment could remain effective within 12 h after birth. METHODS: According to their admission, 152 newborns were enrolled in the < 6 h and 6-12 h after HIE groups. All newborns received conventional treatment combined with mild head hypothermia therapy, according to our routine clinical practice...

Creutzfeldt-Jakob disease (CJD), also known as corticostriate spinal degeneration, subacute spongiform encephalopathy or infectious spongiform encephalopathy, is a type of degenerative disease of the central nervous system caused by prion protein (PrP) infection, which is the most common type of human PrP disease. CJD is genetic and infectious, and is one of the most common causes of rapid progressive dementia with rare clinical occurrence. Herein, we report the clinical conditions of 2 cases of patients with different type of CJD we treated and followed up recently, and a review of relevant literature...

AIM: Phenobarbital (PB) pharmacokinetics (PK) in asphyxiated newborns show large variability, not only explained by hypothermia (HT). We evaluated potential relevant covariates of PK of PB in newborns treated with or without HT for hypoxic-ischemic encephalopathy (HIE). METHODS: Clearance (CL), distribution volume (Vd) and elimination half-life (t1/2 ) were calculated using one-compartment analysis. Covariates were clinical characteristics (weight, gestational age, hepatic, renal, and circulatory status), comedication and HIE severity [time to reach normal aEEG pattern (Tnorm aEEG), dichotomous, within 24 h] and asphyxia severity [severe aspyhxia = pH ≤7...

BACKGROUND: Little is known on amplitude-integrated electroencephalography (aEEG) during the first days after birth in neonates with CHD. Our aim was, therefore, to assess electro-cortical activity using aEEG within the first 72 h after birth in neonates diagnosed prenatally with CHD, and to define independent prenatal and postnatal predictors for abnormal aEEG. METHODS: Neonates with CHD that were admitted to the neonatal intensive care unit between 2010 and 2017 were retrospectively included...

The role of EEG in neonatal seizure detection is well-established, being the multichannel video-EEG the gold standard. However, in the clinical practice often amplitude integrated EEG (aEEG) is used, in order to overcome the difficulties related to EEG use. Areas covered: An overview regarding neonatal seizures, current tools used to detect these (multichannel EEG versus aEEG) with respective strenghts and limitations, and some tools that can implement the use of multichannel EEG in the NICU. Expert commentary: Multichannel video-EEG is still a gold standard for seizure detection...

BACKGROUND: Electroencephalography (EEG) has clinical and prognostic importance after cardiac arrest (CA). Recently, interest in quantitative EEG (qEEG) analysis has grown. The qualitative effects of sedation on EEG are well known, but potentially confounding effects of sedatives on qEEG after anoxic injury are poorly characterized. We hypothesize that sedation increases suppression ratio (SR) and decreases alpha/delta ratio (ADR) and amplitude-integrated EEG (aEEG), and that the magnitude of sedation effects will be associated with outcome...
