Concerning Symptoms in Pediatric Head Injury
Children with severe or worsening headache, altered mental status, persistent vomiting, signs of skull fracture, or Glasgow Coma Scale (GCS) score ≤13 require emergent neuroimaging to rule out intracranial complications, which occur in approximately 2% of cases even with seemingly mild presentations. 1
Red Flag Symptoms Requiring Immediate Action
Symptoms Mandating Emergent Head CT
- Severe or progressively worsening headache, particularly when associated with other risk factors, carries a 1.9% risk of intracranial complications in children with GCS 13-15 1, 2
- Altered mental status including confusion, disorientation, or difficult arousal 1, 3
- Acutely worsening symptoms during observation period require emergent neuroimaging 1
- Signs of basilar skull fracture (Battle's sign, raccoon eyes, hemotympanum, CSF otorrhea/rhinorrhea) - these children have an 11-fold increased risk of requiring inpatient admission 4, 3
- GCS score ≤13 or any decline in GCS 1, 5
- Seizures following head trauma 4, 3
- Focal neurological deficits including weakness, vision changes, or anisocoria 5, 4
High-Risk Mechanisms and Historical Features
- Road traffic accidents (motor vehicle, auto-pedestrian, bicycle) are independent predictors of moderate-to-severe injury with significantly elevated risk 3
- Loss of consciousness lasting >30 seconds or any witnessed LOC 1, 4
- Post-traumatic amnesia to the event or persistent amnesia 1, 4
- Concern for non-accidental trauma increases risk 6-fold for traumatic brain injury on CT 6
Vomiting: Context-Dependent Risk Stratification
Isolated vomiting alone (without other CDR predictors) carries minimal risk - only 0.3% have clinically important TBI and 0.6% have any TBI on CT, making observation without immediate imaging appropriate. 6
However, vomiting combined with other features significantly increases risk:
- Vomiting + skull fracture signs: OR 112.96 for TBI on CT 6
- Vomiting + altered mental status: OR 2.4 for clinically important TBI 6
- Vomiting + headache: OR 2.3-2.55 for TBI 6
- Vomiting + acting abnormally: OR 1.83-1.86 for TBI 6
Initial Treatment Approach
Acute Symptom Management
Administer nonopioid analgesics (ibuprofen 10 mg/kg every 6-8 hours, max 400 mg/dose; or acetaminophen 15 mg/kg every 4-6 hours, max 650 mg/dose) as first-line treatment for headache while simultaneously assessing for red flags. 2, 7
- Never prescribe opioids for post-traumatic headache - they worsen outcomes 2, 7
- Limit analgesic use to 2-3 days per week to prevent medication overuse headache, the most common preventable cause of chronic post-traumatic headache 2
- Do not use 3% hypertonic saline outside research settings despite limited evidence of immediate benefit 1, 2
Observation vs. Imaging Decision
Use validated clinical decision rules (PECARN, CATCH, CHALICE) to determine imaging necessity rather than routine CT for all head injuries. 1, 5
- Skull radiographs should never be used for diagnosis or screening for intracranial injury 1
- Children meeting low-risk criteria can be safely observed without immediate CT 1, 5
- Do not use biomarkers outside research settings for diagnosis 1
Discharge Instructions and Warning Signs
Families must receive explicit instructions to return immediately for: worsening or severe headache, increased drowsiness, repeated vomiting, confusion, vision changes, weakness, difficulty recognizing people or places, or seizures. 1, 5
Additional discharge guidance should include: 1
- Description of injury and expected symptom course
- Instructions for monitoring postconcussive symptoms
- 24-48 hours of relative rest (activities of daily living permitted as tolerated) 1
- Prevention of further injury
- Gradual return to school with accommodations as needed 5
- Clear follow-up instructions at 2-4 weeks 2
Management of Persistent Symptoms
Headache persisting beyond 2 months requires multidisciplinary evaluation including pediatric neurology, reassessment for analgesic overuse, and evaluation for comorbid sleep disturbance, mood disorders, or cognitive dysfunction. 1, 2
- Children with persistent vestibulo-oculomotor dysfunction (dizziness, balance problems) should be referred to vestibular rehabilitation programs 1
- Implement proper sleep hygiene as adequate sleep facilitates TBI recovery 1
- Cognitive dysfunction should be evaluated within the context of other symptoms, as headache pain itself can disrupt cognitive processing 1
Common Pitfalls to Avoid
- Never dismiss severe headache as "just a concussion symptom" without imaging when other risk factors are present - nearly 2% have intracranial injury even with mild presentations 2
- Do not routinely image all children with vomiting - isolated vomiting has <1% risk of significant injury 6
- Avoid excessive analgesic use beyond 2-3 days per week to prevent rebound headache 2
- Do not delay imaging in children with acutely worsening symptoms during observation 1
