What is the appropriate management for a pediatric patient with a subdural hematoma, presenting with confusion, headache, left side weakness, and a Glasgow Coma Scale (GCS) score of 14?

Management of Pediatric Subdural Hematoma with Confusion, Headache, Left-Sided Weakness, and GCS 14

This pediatric patient with subdural hematoma, focal neurological deficit (left-sided weakness), and altered mental status (confusion) requires immediate surgical consultation (Option C), as these findings indicate significant mass effect requiring neurosurgical evaluation for potential evacuation. 1, 2

Rationale for Surgical Consultation

Immediate neurosurgical consultation is mandatory because this patient demonstrates:

• Focal neurological deficit (left-sided weakness) - This indicates significant mass effect and is an absolute indication for surgical evaluation 1
• Altered mental status (confusion) despite GCS 14 - This represents neurological deterioration requiring urgent assessment 1, 2
• GCS 14 with focal deficit - Patients with subdural hematoma and focal neurological deficits have significantly higher rates of requiring craniotomy, with studies showing that 1 in 4 patients with abnormal neurological examination will require surgical treatment 1

Why Other Options Are Inappropriate

Hyperventilation (Option A)

• Should NOT be used routinely - Hyperventilation is reserved only for acute cerebral herniation as a temporizing measure while awaiting emergency neurosurgery 1
• Target PaCO2 should be maintained at 35-40 mmHg during interventions; hypocapnia is only for imminent herniation 1, 3
• This patient shows no signs of herniation (GCS 14, no pupillary abnormalities mentioned) 1

IV Mannitol (Option B)

• Mannitol is indicated for threatened intracranial hypertension or signs of brain herniation, not as first-line management 1
• The FDA label indicates mannitol for reduction of intracranial pressure at 0.25-2 g/kg over 30-60 minutes 4
• However, osmotherapy should only be used after controlling secondary brain insults and in the context of surgical planning, not as standalone treatment 1
• This patient requires definitive surgical evaluation first, not medical temporizing measures 1, 2

Follow with CT in 24 Hours (Option D)

• Completely inappropriate - This patient has focal neurological deficit and altered mental status, which are indications for immediate intervention, not observation 1, 2
• Delayed imaging is only appropriate for asymptomatic or minimally symptomatic patients with small hematomas 5
• Studies show that patients with focal deficits who are observed have significantly worse outcomes 1, 6

Surgical Decision Criteria

The neurosurgeon will evaluate for immediate craniotomy based on:

• Hematoma thickness >5mm with midline shift >5mm - These are absolute surgical indications 1, 2
• Progressive neurological deterioration - The presence of confusion and focal weakness suggests ongoing mass effect 1, 2
• GCS motor score - If motor score is ≤5, this strongly supports surgical evacuation 1

Post-Consultation Management

If surgery is performed, the following monitoring is indicated:

• ICP monitoring should be placed if the patient has preoperative focal deficits, as this meets criteria for postoperative monitoring 1, 3
• Target cerebral perfusion pressure 60-70 mmHg after ICP monitor placement 1, 3
• Maintain systolic BP >100 mmHg or MAP >80 mmHg during all interventions 3

Common Pitfalls to Avoid

• Do not delay neurosurgical consultation for medical management attempts - focal deficits mandate immediate surgical evaluation 1, 2
• Do not use mannitol or hyperventilation as substitutes for surgical consultation in patients with focal deficits 1
• Do not assume GCS 14 means "mild" injury - the presence of focal deficit and confusion indicates significant intracranial pathology requiring urgent intervention 1
• Do not plan for observation or delayed imaging when focal neurological deficits are present 1, 2, 6
