What signs and symptoms should be monitored in a six‑year‑old child after a fall to determine whether emergency evaluation is required?

Monitoring a Six-Year-Old After a Fall: Red Flags for Emergency Evaluation

Remove the child from activity immediately and monitor closely for signs of head injury, loss of consciousness, altered mental status, severe headache, repeated vomiting, seizures, or focal neurological deficits—any of these warrant emergency department evaluation. 1

Critical Warning Signs Requiring Immediate Emergency Services

Neurological Red Flags

• Loss of consciousness of any duration (occurs in <10% of concussions but signals potentially serious injury) 1
• Altered mental status or Glasgow Coma Scale <15 at 2 hours post-injury 1
• Seizure activity following the fall 1
• Focal neurological deficits including weakness, numbness, or cranial nerve abnormalities 1
• Worsening mental status or progressive deterioration over time 1, 2

Physical Examination Findings

• Signs of skull fracture: palpable step-off, depression, or suspected open fracture 1
• Signs of basilar skull fracture: Battle's sign (bruising behind ears), raccoon eyes (periorbital bruising), hemotympanum, or CSF leak from nose/ears 2
• Severe or worsening headache that progressively intensifies 1, 2
• Repeated vomiting (more than once, especially if worsening) 1, 2

Behavioral and Cognitive Changes

• Persistent confusion or disorientation 1, 2
• Amnesia (inability to remember events before or after the fall) 1
• Mental fogginess or difficulty concentrating 1
• Unusual irritability or behavioral changes 1

Moderate Concern Signs (Warrant Close Observation)

Symptoms to Monitor Over Several Hours

• Single episode of vomiting (common but monitor for recurrence) 2
• Mild headache that remains stable or improves 1
• Dizziness or balance problems (test with tandem gait or Romberg test) 1
• Light or noise sensitivity 1
• Fatigue or drowsiness (but arousable) 1

Physical Findings

• Scalp hematoma: Large, boggy, or non-frontal location increases concern 2, 3
• Facial injury in children <6 months raises suspicion for more serious trauma 1

Low-Risk Indicators (May Not Require Emergency Evaluation)

Children who meet ALL of the following criteria are at very low risk for clinically significant brain injury 2:

• Normal mental status throughout observation
• No loss of consciousness
• No vomiting
• Non-severe injury mechanism (simple fall from standing or low height)
• No signs of basilar skull fracture
• No severe headache
• No clinical worsening over time
• No multiple concerning symptoms

Special Considerations for Six-Year-Olds

Age-Specific Factors

• Children <12 months have the highest risk of occult intracranial injury without obvious symptoms, but a 6-year-old can typically verbalize symptoms and localize pain 1, 4
• At age 6, the child should be able to communicate headache severity, visual changes, and other symptoms 1

Mechanism of Injury Assessment

• High-risk mechanisms include: fall from >3 feet, high-velocity impact, or motor vehicle collision 2, 3
• Low-risk mechanisms include: ground-level falls or minor bumps during play 2

Critical Pitfalls to Avoid

Do Not Rely on Skull X-Rays

• Skull radiographs are NOT adequate screening tools for intracranial injury—up to 50% of intracranial injuries occur without skull fracture 5
• If imaging is needed, CT head without contrast is the appropriate study 1, 5

Consider Non-Accidental Trauma

• Inconsistent history with injury pattern warrants further evaluation 1, 6
• Multiple injuries at different stages of healing raise concern for abuse 1
• Maintain high suspicion if the mechanism doesn't match the injury severity 1

Observation Period

• Monitor for several hours after injury, as symptoms can evolve 1
• Instruct parents to watch for deterioration overnight, including difficulty arousing, repeated vomiting, or worsening headache 1, 2
• Provide clear return precautions for signs requiring immediate ED evaluation 1

When to Image

CT head is indicated if: 1, 2

• Glasgow Coma Scale <15 at 2 hours post-injury
• Suspected skull fracture on examination
• History of worsening headache
• Irritability on examination
• Any focal neurological signs
• Prolonged loss of consciousness

Observation without imaging is appropriate if: 2

• Child meets all low-risk criteria listed above
• Parents are reliable and can monitor at home
• Clear return precautions are provided
