Do not delay transfer for repeat imaging when initial CT is diagnostic
Temporizing measures bridge to definitive surgical care
Hyperosmolar therapy
Airway protection
Coagulopathy reversal
Conservative vs surgical management
Conservative management applies to strict criteria only
EDH < 30 cm3, thickness < 15 mm, shift < 5 mm, GCS > 8, no deficits
Approximately 11% of conservatively managed patients require delayed surgery
Close monitoring is mandatory for conservative pathway
Neurosurgical center requirement
Serial CT protocol
Posterior fossa EDH: lower surgical threshold
Rapid brainstem compression risk
Even small volumes can be lethal
Anticoagulation and risk
Warfarin has highest pharmacovigilance signal for EDH (ROR 29.2)
DOACs also increase EDH risk though pharmacovigilance signal lower than warfarin
Reversal must be immediate and complete before surgery
Re-anticoagulation after EDH individualized
Typically 4-8 weeks minimum before restarting
Weighing thrombosis vs rebleeding risk with neurosurgery and medicine
ECG and cardiac monitoring rationale
ECG abnormalities in up to 88% of severe TBI
ST depression independently associated with 48-hour mortality
QTc prolongation independently associated with 48-hour mortality
Changes are neurogenic from catecholamine surge peaking at 24 hours
Primary cardiac pathology must be excluded especially in older patients
Patient Discharge Instructions
copy discharge instructions
Epidural hematoma home care
You had a blood clot inside your skull that was treated
Rest at home and avoid strenuous activity
No driving until cleared by your neurosurgeon
No contact sports or high-risk activities until further notice
No alcohol or sedating medications unless specifically approved by your doctor
Take all prescribed medications including anti-seizure medication exactly as directed
Warning signs to return to emergency room immediately
Worsening or severe headache
New confusion or unusual drowsiness
Weakness or numbness in arm or leg
Trouble speaking or understanding speech
Vision changes
Vomiting that will not stop
Seizure
One pupil larger than the other
Loss of consciousness even briefly
Follow-up instructions
Neurosurgery appointment within 1-2 weeks
Repeat CT scan as scheduled by your neurosurgeon
Do not stop anti-seizure medications without neurosurgeon approval
Recovery expectations
Headache, fatigue, and difficulty concentrating are common in early weeks
Post-concussive symptoms may persist weeks to months
Report any new or worsening neurological symptoms immediately
