Management of elevated intracranial pressure

Area of Science:

• Neurology
• Critical Care Medicine

Background:

• Elevated intracranial pressure (ICP) is a critical condition associated with severe head injuries, brain tumors, and stroke.
• Symptoms of elevated ICP can be subtle and difficult to differentiate from other neurological conditions.

Purpose of the Study:

• To review the pathophysiology, clinical manifestations, monitoring, and management of elevated ICP.
• To discuss the detailed use of barbiturate coma for refractory ICP.

Main Methods:

• Review of existing literature on ICP management.
• Discussion of ICP monitoring techniques (e.g., intraventricular catheter, Camino fiber optic system).
• Analysis of conventional treatments (physiologic and pharmacologic) and high-dose barbiturate therapy (pentobarbital).

Main Results:

• ICP monitoring is vital for early detection before clinical signs appear.
• Conventional treatments include CSF removal, fluid restriction, hyperventilation, sedation, and diuretics.
• High-dose barbiturates, particularly pentobarbital, show improved survival rates in refractory ICP cases when combined with conventional therapies.

Conclusions:

• Aggressive therapy and intensive monitoring are essential for managing elevated ICP.
• Barbiturate coma, especially with pentobarbital, offers a survival benefit for patients with refractory ICP.
• Close monitoring of pentobarbital serum concentrations is necessary due to increased clearance during prolonged therapy.
