What is the immediate management for a patient with a left parietooccipital hypertensive intracerebral hemorrhage?

Immediate Management of Left Parietooccipital Hypertensive Intracerebral Hemorrhage

Admit the patient immediately to a neuroscience intensive care unit or stroke unit with continuous neurological monitoring, and if systolic blood pressure is ≥220 mmHg, initiate careful IV blood pressure lowering to <180 mmHg; if systolic BP is 150-220 mmHg, lower acutely to 140 mmHg using IV labetalol or nicardipine. 1, 2

Critical Initial Actions (First Hour)

Immediate Admission and Monitoring

• Transfer to neuroscience intensive care unit or dedicated stroke unit with physician and nursing neuroscience acute care expertise 1
• Initiate continuous or hourly neurological assessments using Glasgow Coma Scale for the first 24 hours to detect early deterioration 2
• Establish continuous cardiac monitoring for at least 24 hours to screen for atrial fibrillation and serious arrhythmias 1

Blood Pressure Management Strategy

For SBP 150-220 mmHg (most common scenario):

• Initiate acute IV blood pressure lowering to target SBP of 140 mmHg within 6 hours of symptom onset 1
• Use IV labetalol as first-line agent (no contraindications) or IV nicardipine for precise titration 1, 2
• Avoid GTN patches completely - the RIGHT-2 trial demonstrated greater hematoma growth and poorer outcomes in 145 ICH patients who received GTN compared to controls 2
• Monitor BP every 15 minutes during active titration 2
• Strictly avoid dropping SBP below 110 mmHg to prevent cerebral hypoperfusion 1

For SBP ≥220 mmHg:

• Initiate careful acute BP lowering with IV therapy to <180 mmHg 1
• Use short-acting IV agents allowing precise titration 1

Critical pitfall: Excessive acute BP drops (>70 mmHg) may cause acute kidney injury and early neurological deterioration - avoid aggressive lowering below target 1

Reversal of Antithrombotic Therapy

If patient is on anticoagulation:

• Stop all anticoagulation immediately 1
• For warfarin with INR ≥2.0: administer four-factor prothrombin complex concentrate immediately, followed by IV vitamin K to prevent later INR increase 1
• For dabigatran: administer idarucizumab immediately 1
• For factor Xa inhibitors (apixaban, rivaroxaban, edoxaban): administer andexanet alfa or four-factor PCC if specific antidote unavailable 1
• For heparin (unfractionated or low-molecular-weight): administer IV protamine sulfate 1

If patient is on antiplatelet therapy:

• Stop aspirin, clopidogrel, or other antiplatelet agents immediately 1
• Do NOT administer platelet transfusions - RCT data show worse outcomes in ICH patients receiving antiplatelet therapy who are treated with platelet infusion 1

Secondary Management (First 24-48 Hours)

Intracranial Pressure Management

Indications for ICP monitoring and treatment:

• Glasgow Coma Scale ≤8 with evidence of elevated ICP 3
• Clinical signs of transtentorial herniation 3
• Significant intraventricular hemorrhage with hydrocephalus 3

If elevated ICP develops:

• Administer 3% hypertonic saline as 2 ml/kg bolus over 15-20 minutes for acute ICP crisis 3
• Initiate continuous infusion of 3% hypertonic saline targeting serum sodium 145-155 mmol/L for sustained control 3
• Monitor serum sodium within 6 hours of initiating therapy and every 6 hours thereafter, avoiding levels >155-160 mmol/L 3
• Elevate head of bed 20-30 degrees to assist venous drainage 3
• Prefer hypertonic saline over mannitol - provides more rapid ICP reduction, greater cerebral perfusion pressure increases, and longer duration of action 3

Important caveat: Despite proven ICP reduction, hypertonic saline does not improve neurological outcomes or survival 3

Neurosurgical Consultation

Urgent neurosurgical consultation required for:

• Cerebellar hemorrhage with altered consciousness or new brainstem symptoms 1
• Acute hydrocephalus requiring external ventricular drainage 1
• Consider early consultation for decompressive craniectomy in select patients 1

Note: Surgical intervention has not been shown superior to conservative management for most supratentorial ICH, though may be considered in select patients with GCS 9-12 1

Venous Thromboembolism Prophylaxis

• Initiate intermittent pneumatic compression beginning day of hospital admission 1
• Consider pharmacological prophylaxis with LMWH or UFH after documenting hemorrhage stability on CT, typically 24-48 hours after onset 1
• Graduated compression stockings alone are less effective than pharmacological prophylaxis 1

Additional Critical Management

Glucose control:

• Monitor glucose levels and avoid both hyperglycemia and hypoglycemia 1

Seizure management:

• Treat clinical seizures with antiseizure drugs 1
• Treat electrographic seizures on EEG in patients with altered mental status 1
• No role for prophylactic anticonvulsant treatment 1

Dysphagia screening:

• Perform formal dysphagia screening before initiating oral intake to reduce pneumonia risk 1

Goals of care:

• Establish goals with patient/substitute decision-maker 1
• Defer DNR orders or palliative care decisions for 24-48 hours to allow response assessment to medical therapy, except in patients with preexisting wishes 1

Key Monitoring Parameters

• Neurological assessments: hourly for first 24 hours 2
• Blood pressure: every 15 minutes during active titration, then every 30-60 minutes for 24-48 hours 2
• Cardiac monitoring: continuous for at least 24 hours 1
• Serum sodium (if on hypertonic saline): every 6 hours 3
