“New Model Aims to Predict Seizures in Newborns with Brain Injury”
In a recent study focused on neonates suffering from hypoxic–ischemic encephalopathy (HIE), researchers aimed to tackle the challenge of identifying electroencephalographic seizures (ES) efficiently. Monitoring for these seizures is typically done using continuous electroencephalographic (CEEG) methods, which can be resource-intensive. The team wanted to create a predictive model that could help identify which babies are more likely to experience seizures, ultimately streamlining the process and reducing the need for prolonged monitoring.
The study involved 260 neonates with HIE, and the findings were quite revealing. About 32% of these infants experienced electroencephalographic seizures. However, if doctors only monitored them for 24 hours, they would miss about 7% of those with later-onset seizures. To catch the majority of seizures, they found that extending CEEG to 63 hours would identify 90% of cases, while a whopping 74 hours would be needed to catch 95%. The model developed by the researchers utilized the first hour of monitoring, focusing on two key EEG indicators: continuity and epileptiform discharges.
The predictive model showed promising results, boasting a sensitivity of 94%—meaning it was very good at identifying those who actually had seizures—albeit with a lower specificity of 45%. The model successfully categorized neonates into low, moderate, and high-risk groups for seizures. Notably, for those in the low-risk category, just six hours of monitoring was enough to catch all seizure cases, while moderate and high-risk groups required significantly longer monitoring times of 75 and 63 hours, respectively.
The implications of this research are significant as they provide a more targeted approach to monitoring at-risk neonates. By using this model, healthcare providers can prioritize which infants need more intensive EEG monitoring and potentially reduce unnecessary resource use while ensuring that those who need attention are monitored appropriately. This evidence-based strategy could lead to better care for vulnerable infants, ultimately improving outcomes in this critical period of their lives.
