Insights
Neonatal seizures are common and dangerous for newborns, often occurring without visible symptoms. Expert interpretation of electroencephalography (EEG) monitoring is crucial for accurate diagnosis and treatment of these critical brain events.
Area of Science:
- Neonatal neurology
- Neurocritical care
- Pediatric neurology
Background:
- Neonatal neurocritical intensive care aims to protect the newborn brain from injury.
- Neonatal seizures are the most common neurological emergency, indicating potential underlying disease and increasing mortality.
- Subclinical seizures are frequent in newborns, complicating diagnosis and management.
Purpose of the Study:
- To highlight the critical need for expert interpretation of EEG monitoring in neonatal care.
- To discuss the challenges and limitations of current neuromonitoring techniques.
- To emphasize the importance of automated seizure detection for timely intervention.
Main Methods:
- Review of conventional electroencephalography (cEEG) and amplitude-integrated EEG (aEEG) for neonatal brain wave monitoring.
- Discussion of cEEG with video as the gold standard for seizure diagnosis and treatment.
- Exploration of the limitations in access to real-time EEG interpretation in neonatal units.
Main Results:
- EEG monitoring's efficacy is dependent on expert interpretation.
- Both cEEG and aEEG have distinct strengths and weaknesses regarding seizure detection sensitivity and ease of interpretation.
- Many neonatal units lack access to cEEG or real-time interpretation services.
Conclusions:
- Expert interpretation is essential for the clinical utility of EEG monitoring in newborns.
- Automated seizure detection algorithms are needed to provide sensitive, specific, and real-time analysis of EEG data.
- Improving access to and interpretation of neuromonitoring is vital for optimizing neonatal brain injury care.
Abstract:
Neonatal neurocritical intensive care is dedicated to safeguarding the newborn brain by prioritising clinical practices that promote early identification, diagnosis and treatment of brain injuries. The most common newborn neurological emergency is neonatal seizures, which may also be the initial clinical indication of neurological disease. A high seizure burden in the newborn period independently contributes to increased mortality and morbidity. The majority of seizures in newborns are subclinical (without clinical presentation), and hence identification may be difficult. Neuromonitoring techniques most frequently used to monitor brain wave activity include conventional electroencephalography (cEEG) or amplitude-integrated EEG (aEEG). cEEG with video is the gold standard for diagnosing and treating seizures. Many neonatal units do not have access to cEEG, and frequently those that do, have little access to real-time interpretation of monitoring. IMPACT: EEG monitoring is of no benefit to an infant without expert interpretation. Whilst EEG is a reliable cot-side tool and of diagnostic and prognostic use, both conventional EEG and amplitude-integrated EEG have strengths and limitations, including sensitivity to seizure activity and ease of interpretation. Automated seizure detection requires a sensitive and specific algorithm that can interpret EEG in real-time and identify seizures, including their intensity and duration.
