Core Principles of Neurointensive Care

The practice of neurointensiv centers on several fundamental principles designed to prevent secondary brain injury, optimize cerebral physiology, and enhance neurological recovery.

1. Intracranial Pressure (ICP) Management

Maintaining ICP within normal limits (typically <20 mm Hg) is crucial, as elevated ICP can compromise cerebral perfusion and lead to brain herniation. Strategies include:

• Head elevation (30 degrees)
• Sedation and analgesia
• Hyperosmolar therapy (e.g., mannitol, hypertonic saline)
• CSF diversion via ventriculostomy
• Surgical decompression in refractory cases

2. Cerebral Perfusion Pressure (CPP) Optimization

CPP = Mean arterial pressure (MAP) - ICP. Ensuring adequate CPP (usually 60-70 mm Hg) balances perfusion against the risk of edema or hemorrhage. Continuous monitoring of MAP and ICP guides therapy.

3. Monitoring Modalities

• Invasive: ICP sensors, cerebral microdialysis, brain tissue oxygen monitors.
• Non-invasive: Transcranial Doppler (TCD), near-infrared spectroscopy (NIRS), advanced neuroimaging.

4. Temperature Control

Fever exacerbates neuronal injury; thus, temperature management via cooling devices or antipyretics is standard.
