Association of EEG Response to Hypertonic Saline and Neurologic Outcomes in Pediatric Acute Brain Injury.

Background: EEG is a critical tool for neuromonitoring and neuroprognostication in children with acute brain injury. Quantitative EEG (qEEG), particularly the alpha-delta ratio (ADR), can detect worsening cerebral ischemia in adults, but it is unknown whether it can identify more subtle and transient changes in cerebral blood flow, such as those induced by hypertonic saline (HTS), in children. We aimed to determine whether we could identify a cohort of patients with an ADR response to HTS and to evaluate the association between an ADR response and neurologic outcomes in critically ill children with acute brain injury.

Influenza-Associated Acute Necrotizing Encephalopathy in US Children.

Importance: Acute necrotizing encephalopathy (ANE) is a rare, but severe, neurologic condition for which epidemiologic and management data remain limited. During the 2024-2025 US influenza season, clinicians at large pediatric centers anecdotally reported an increased number of children with influenza-associated ANE, prompting this national investigation.

Objective: To understand the clinical presentation, interventions, and outcomes among US children diagnosed with influenza-associated ANE.

Practice patterns for acquiring neuroimaging after pediatric in-hospital cardiac arrest.

Aims: To determine which patient and cardiac arrest factors were associated with obtaining neuroimaging after in-hospital cardiac arrest, and among those patients who had neuroimaging, factors associated with which neuroimaging modality was obtained.

Methods: Retrospective cohort study of patients who survived in-hospital cardiac arrest (IHCA) and were enrolled in the ICU-RESUS trial (NCT02837497).

Results: We tabulated ultrasound (US), CT, and MRI frequency within 7 days following IHCA and identified patient and cardiac arrest factors associated with neuroimaging modalities utilized.

Lack of association of first and second-line medication dosing and progression to refractory status epilepticus in children.

Purpose: Evaluate the relationship between first and second-line medication dosing and progression to refractory status epilepticus (RSE) in children.

Methods: This is a retrospective analysis of prospectively collected data from September 2014 to February 2020 of children with status epilepticus (SE) who received at least two antiseizure medications (ASMs). We evaluated the risk of developing RSE after receiving a low total benzodiazepine dose (lower than 100 % of the minimum recommended dose for each benzodiazepine dose administered within 10 min) and a low first non-benzodiazepine ASM dose (lower than 100 % of the minimum recommended dose of non-benzodiazepine ASM given as the first single-dose) using a logistic regression model, adjusting for confounders such as time to ASMs.

Association of EEG characteristics with outcomes following pediatric ICU cardiac arrest: A secondary analysis of the ICU-RESUScitation trial.

Background And Objectives: There are limited tools available following cardiac arrest to prognosticate neurologic outcomes. Prior retrospective and single center studies have demonstrated early EEG features are associated with neurologic outcome. This study aimed to evaluate the prognostic value of EEG for pediatric in-hospital cardiac arrest (IHCA) in a prospective, multicenter study.

A quantitative EEG index for the recognition of arterial ischemic stroke in children.

Objective: To describe and assess performance of the Correlate Of Injury to the Nervous system (COIN) index, a quantitative electroencephalography (EEG) metric designed to identify areas of cerebral dysfunction concerning for stroke.

Methods: Case-control study comparing continuous EEG data from children with acute ischemic stroke to children without stroke, with or without encephalopathy. COIN is calculated continuously and compares EEG power between cerebral hemispheres.

Efficacy of IV Valproic Acid and Oral Valproic Acid Tapers for the Treatment of Pediatric Headaches in the Emergency Department.

Background And Objectives: Pediatric headaches, including migraine, are a common reason for emergency department (ED) presentation. IV valproic acid (VPA) followed by oral VPA tapers are often used to abort pediatric headache and reduce recurrence, though limited data exist regarding this approach. This study evaluated the effectiveness of IV VPA and oral VPA tapers for the treatment of acute pediatric headaches in the ED in preventing return encounters.

Development and Evaluation of a Child Neurology Resident Curriculum for Communication Around Serious Illness.

Communication around serious illness is a core competency for all residencies. One-fifth of neurology residencies have no curriculum. Published curricula use didactics or role-play to assess confidence performing this skill without evaluation in clinical settings.

Use of Continuous Ketamine Infusion as an Adjunctive Agent in Young Infants With Refractory and Super Refractory Status Epilepticus: A Case Series.

Continuous ketamine infusions have been studied as an adjunctive agent for refractory status epilepticus (RSE) and super refractory status epilepticus (SRSE) in older children and adults. However, minimal information exists on the efficacy, safety, and dosing for continuous ketamine in young infants. We present the clinical course of 3 young infants with RSE and SRSE who received continuous ketamine in conjunction with other antiseizure medications.

Review of Noninvasive Neuromonitoring Modalities in Children II: EEG, qEEG.

Critically ill children with acute neurologic dysfunction are at risk for a variety of complications that can be detected by noninvasive bedside neuromonitoring. Continuous electroencephalography (cEEG) is the most widely available and utilized form of neuromonitoring in the pediatric intensive care unit. In this article, we review the role of cEEG and the emerging role of quantitative EEG (qEEG) in this patient population.

Survey of Pediatric ICU EEG Monitoring-Reassessment After a Decade.

Purpose: In 2011, the authors conducted a survey regarding continuous EEG (CEEG) utilization in critically ill children. In the interim decade, the literature has expanded, and guidelines and consensus statements have addressed CEEG utilization. Thus, the authors aimed to characterize current practice related to CEEG utilization in critically ill children.

The Spectrum of Quantitative EEG Utilization Across North America: A Cross-Sectional Survey.

Background: Continuous electroencephalography (cEEG) is commonly used for neuromonitoring in pediatric intensive care units (PICU); however, there are barriers to real-time interpretation of EEG data.
