Management of Acute Parenchymal Hemorrhage
Immediate Assessment and Stabilization
- The American Heart Association recommends immediate medical management with aggressive blood pressure control to a systolic target of 140 mmHg, correction of any coagulopathy, and close neurological monitoring in an ICU setting for patients with acute parenchymal hemorrhage 1
- Avoid permissive hypotension strategies used in trauma as these apply to extracranial bleeding, not intracerebral hemorrhage 2, 3
- Immediately reverse any anticoagulation or antiplatelet therapy, checking INR, aPTT, platelet count, and anticoagulant history, according to the American Stroke Association 1
- For warfarin, administer prothrombin complex concentrates (PCC) for rapid reversal, as recommended by the Critical Care Society 4
Neurological Monitoring and ICU Care
- Perform baseline and serial NIHSS scores at defined intervals (immediately, 24 hours, 72 hours, 7-10 days), as suggested by the Stroke Society 7
- Obtain non-contrast CT at 24 hours to assess for hematoma expansion, then at 7-10 days, 30 days, and 90 days, according to the Stroke Society 7
- Monitor continuously for signs of neurological deterioration requiring emergency imaging, as recommended by the American Heart Association 1, 7
Surgical Decision-Making
- Consider ICP monitoring for patients with GCS ≤8, clinical evidence of transtentorial herniation, or significant mass effect, according to the American Heart Association 1
- Maintain cerebral perfusion pressure (CPP) of 50-70 mmHg depending on autoregulation status, as recommended by the American Heart Association 1
- Ventricular drainage is reasonable for hydrocephalus treatment, especially in patients with decreased level of consciousness, according to the American Heart Association 1
Ongoing Medical Management
- Employ early measures to reduce heat loss and maintain normothermia, as recommended by the Critical Care Society 5
- Target hemoglobin of 70-90 g/L if transfusion is necessary, according to the Critical Care Society 5
- Patients with severe traumatic brain injury should not be managed with different Hb thresholds than other critically ill patients, as suggested by the Critical Care Society 9
Critical Pitfalls to Avoid
- Never use corticosteroids for intracerebral hemorrhage, as they are contraindicated, according to the American Heart Association 1
- Avoid excessive fluid resuscitation that may worsen cerebral edema, as recommended by the Critical Care Society 8
- Do not rely on single hematocrit measurements as isolated markers for bleeding, according to the Critical Care Society 2, 3
