Management of Neonatal Seizures

Diagnostic Approach

  • The American College of Radiology recommends urgent neuroimaging, including head ultrasound as initial bedside imaging if the infant is unstable or MRI is not immediately available, and MRI with diffusion-weighted imaging as the gold standard to identify etiology 1, 2
  • The American Academy of Pediatrics suggests that laboratory investigations, including complete blood count, electrolytes, glucose, calcium, and magnesium, should be performed 3
  • Blood culture should be considered if infection is suspected, according to the American College of Radiology 2
  • Metabolic screening and genetic testing should be considered if no clear etiology is found, as recommended by the American College of Radiology 1

Treatment and Management

  • The American Academy of Pediatrics recommends ensuring patent airway, adequate breathing, and circulation, and monitoring vital signs, including heart rate, blood pressure, temperature, and oxygen saturation 3
  • Establishing IV access for medication administration and blood sampling is essential, according to the American College of Radiology 1
  • For drug withdrawal-associated seizures, the specific treatment may vary based on the drug of exposure, as suggested by the American Academy of Pediatrics 4, 5
  • Prophylactic use of antiseizure medications in neonates without confirmed seizures is not recommended, according to the International Journal of Stroke 3

Prognosis and Outcome

  • The prognosis depends primarily on the underlying etiology, as stated by the American College of Radiology 1, 2
  • Absence of major cerebral lesions on MRI is highly predictive of normal neurological outcome, according to the American College of Radiology 2
