Management of Subdural Hematoma in Elderly Trauma Patients

Immediate Priorities

For an elderly patient with subdural hematoma following trauma, presenting with signs of increased intracranial pressure and severe symptoms, urgent neurosurgical consultation and intervention is required immediately after stabilization of life-threatening hemorrhage, according to the World Journal of Emergency Surgery 1
Control any life-threatening systemic hemorrhage before addressing the intracranial pathology, as recommended by the World Journal of Emergency Surgery 1
Maintain systolic blood pressure >100 mmHg or mean arterial pressure >80 mmHg during all interventions, as suggested by the World Journal of Emergency Surgery 1
Target cerebral perfusion pressure ≥60 mmHg if ICP monitoring is established, as recommended by the World Journal of Emergency Surgery and Praxis Medical Insights 1, 2

Perform immediate neurological evaluation including Glasgow Coma Scale motor score and pupillary examination, as recommended by the World Journal of Emergency Surgery 1
Obtain non-contrast head CT scan to characterize hematoma size, location, mass effect, and midline shift, according to Praxis Medical Insights 3
Verify anticoagulant or antiplatelet use, as these dramatically increase expansion risk, as noted by Praxis Medical Insights 3

Subdural hematoma thickness >5 mm with midline shift >5 mm requires immediate surgical evacuation, as recommended by Anaesthesia and Praxis Medical Insights 4, 5
Any symptomatic subdural hematoma causing neurological deterioration requires immediate surgical evacuation, according to Anaesthesia 4
Signs of cerebral herniation or severe intracranial hypertension require immediate surgical evacuation, as recommended by the World Journal of Emergency Surgery and Anaesthesia 1, 4

Target parameters before neurosurgery include platelet count >50,000/mm³, PT/aPTT <1.5 times normal control, and use of point-of-care testing (TEG/ROTEM) if available, as recommended by the World Journal of Emergency Surgery 1
Reverse anticoagulation emergently in consultation with neurosurgery, according to Praxis Medical Insights 3

Maintain PaO₂ 60-100 mmHg, PaCO₂ 35-40 mmHg, and avoid hypocapnia except temporarily for acute herniation, as recommended by the World Journal of Emergency Surgery 1
Transfuse RBCs for hemoglobin <7 g/dL; consider higher threshold in elderly with cardiovascular disease, according to the World Journal of Emergency Surgery 1

ICP monitoring is indicated for all comatose patients at risk for intracranial hypertension after hemorrhage control, as recommended by the World Journal of Emergency Surgery 1
Target parameters include maintaining CPP 60-70 mmHg and avoiding hypocapnia-induced cerebral vasoconstriction, according to Praxis Medical Insights 2, 5
Monitor for hematoma re-accumulation with serial neurological exams and consider repeat CT at 24 hours, especially in anticoagulated patients, as recommended by Praxis Medical Insights 3

Do not delay surgery in symptomatic patients with mass effect while awaiting "optimal" timing, as recommended by the World Journal of Emergency Surgery and Anaesthesia 1, 4
Do not perform non-emergent extracranial surgery in the presence of intracranial hypertension, according to Anaesthesia 6
Do not use 4% albumin in severe TBI patients, as it increases mortality, as noted by Anaesthesia 6
Do not underestimate small hematomas in anticoagulated elderly patients—they expand rapidly, according to Praxis Medical Insights 3, 5
Do not prioritize subdural over epidural when both present—epidurals herniate faster, as recommended by Praxis Medical Insights 5
