Interactive Decision Tree
Algorithm Steps
- ▶Start
Suspected Elevated ICP
Clinical signs or radiographic evidence
- ●Action
Recognize ICP Signs
Clinical indicators
- Headache, vomiting, papilledema (chronic)
- Altered consciousness (acute)
- Cushing triad: HTN, bradycardia, irregular respirations
- Pupil changes (unilateral dilation)
- Posturing (decorticate/decerebrate)
- ●Action
Immediate Measures (Tier 0)
Basic interventions
- Head of bed 30°, head midline
- Avoid jugular compression
- Treat fever aggressively (goal <38°C)
- Treat pain and agitation
- Ensure adequate sedation if intubated
- ◆Decision
Impending Herniation?
Immediate life threat
- Fixed dilated pupil(s)
- Rapid neuro deterioration
- Loss of brainstem reflexes
- Posturing
- ●Action
Emergent Osmotherapy
Immediate hyperosmolar therapy
- Mannitol 1-1.5 g/kg IV bolus
- OR Hypertonic saline 23.4% 30mL (central line)
- OR Hypertonic saline 3% 250-500mL
- Hyperventilate briefly to PaCO2 30-35
- This is bridging to definitive treatment
- ●Action
Urgent CT Head
Identify etiology and surgical lesion
- Mass lesion (tumor, hematoma)
- Hydrocephalus
- Cerebral edema pattern
- Midline shift, cistern effacement
- ◆Decision
Surgical Lesion?
Is there an operable cause?
- Epidural/subdural hematoma
- Large ICH with mass effect
- Obstructive hydrocephalus
- Tumor with herniation
- ●Action
Surgical Intervention
Emergent decompression
- Craniotomy for mass evacuation
- EVD for hydrocephalus
- Decompressive craniectomy (refractory)
- Tumor debulking if feasible
- ●Action
ICP Monitor Placement
If not already surgical candidate
- EVD preferred (allows CSF drainage)
- Parenchymal monitor alternative
- Target ICP <22 mmHg (BTF)
- Target CPP 60-70 mmHg
- ●Action
Tier 1 ICP Management
First-line medical therapies
- CSF drainage via EVD (10-20 mL prn)
- Osmotherapy: mannitol or HTS
- Mannitol 0.25-1 g/kg q4-6h
- 3% saline continuous infusion
- Serum osmolality target <320
- ◆Decision
ICP Controlled?
Is ICP <22 with Tier 1?
- ●Action
ICP Controlled
Maintain and wean
- Continue monitoring
- Wean therapies slowly
- Treat underlying cause
- Watch for rebound
- ✓Outcome
Ongoing Neurocritical Care
ICU management continues
- ●Action
Tier 2 Therapies
Escalation for refractory ICP
- Deeper sedation (propofol/midazolam)
- Neuromuscular blockade
- Mild hyperventilation (PaCO2 30-35)
- Hypothermia (32-34°C) - controversial
- Higher osmolar targets
- ●Action
Tier 3 / Rescue Therapies
Last resort options
- Barbiturate coma (pentobarbital)
- Decompressive craniectomy
- Moderate hypothermia
- High-dose HTS boluses
