What is the appropriate management for a 7-month-old female presenting with a possible seizure?

Focused Neurological Examination for a 7-Month-Old Female with Possible Seizure

For a 7-month-old female presenting with a possible seizure, immediate EMS activation is required as this is a first-time seizure in an infant under 6 months of age, which is considered a medical emergency requiring hospital evaluation. 1

Initial Assessment

Vital Signs and General Appearance

• Blood pressure measurement (required for all children with afebrile seizures)
• Temperature (to identify febrile vs. afebrile seizure)
• Heart rate and respiratory rate
• Oxygen saturation
• Level of consciousness and responsiveness

Seizure Characteristics Documentation

• Duration of seizure (>5 minutes requires emergency intervention)
• Type of movements (generalized vs. focal)
• Eye movements during event
• Presence of cyanosis or breathing difficulties
• Post-ictal state (confusion, sleepiness, return to baseline)

Focused Neurological Examination Components

Level of Consciousness

• Assess alertness, interaction with caregivers
• Response to visual and auditory stimuli
• Consolability

Cranial Nerve Assessment

• Pupillary size, symmetry, and reactivity to light
• Eye movements and tracking of objects
• Facial symmetry (observe during crying)
• Swallowing and gag reflex

Motor Examination

• Observe for asymmetry in spontaneous movements
• Tone assessment (hypotonia vs. hypertonia)
• Strength testing through age-appropriate maneuvers:
  • Resistance to passive movement
  • Ability to maintain posture against gravity
  • Grasp reflex

Developmental Assessment

• Age-appropriate milestones (sitting with support, reaching for objects)
• Head control
• Social interaction

Additional Examination Elements

• Head circumference measurement (to assess for hydrocephalus)
• Fontanelle examination (bulging may indicate increased intracranial pressure)
• Skin examination for neurocutaneous markers (café-au-lait spots, ash leaf macules)
• Signs of trauma or abuse

Management Considerations

Immediate Management

• Place the child on their side in recovery position to prevent aspiration 1
• Do not restrain the child or put anything in their mouth 1
• Avoid administering antipyretics if febrile, as they do not prevent subsequent febrile seizures 1

Diagnostic Workup

• Blood glucose measurement (especially if still seizing or somnolent) 2
• Consider neuroimaging based on clinical presentation
  • MRI is preferred over CT for most cases of new-onset seizures 1
  • Cranial ultrasound may be useful as initial imaging if the infant is unstable 1

Hospital Admission Criteria

• All infants under 1 year of age with afebrile seizures should be admitted 2
• For febrile seizures, admission is indicated if:
  • Age under 18 months
  • Complex febrile seizure (>15 minutes, focal features, or multiple seizures within 24 hours) 1
  • Signs of intracranial infection

Common Pitfalls to Avoid

• Failing to distinguish between simple and complex febrile seizures
• Missing signs of increased intracranial pressure
• Overlooking subtle focal neurological deficits that may indicate focal pathology
• Unnecessary administration of anticonvulsants for simple febrile seizures
• Forgetting that seizures in this age group may be the first manifestation of serious underlying conditions including infections, metabolic disorders, or structural abnormalities

Remember that in infants this young, seizures require thorough evaluation as they have a higher likelihood of representing significant underlying pathology compared to older children with febrile seizures.
