Initial Diagnosis and Management of Acutely Elevated Intracranial Pressure

Area of Science:

• Neuroscience
• Critical Care Medicine
• Emergency Medicine

Background:

• Acutely elevated intracranial pressure (ICP) poses significant risks to patient mortality and neurological outcomes.
• Current treatment guidelines are often specific to etiologies like trauma or stroke, limiting applicability to diverse causes.
• Timely management decisions for elevated ICP are frequently required before the underlying cause is definitively identified.

Purpose of the Study:

• To present an organized, evidence-based approach for the recognition and initial management of elevated ICP.
• To guide clinicians in the critical first minutes to hours of resuscitation for patients with suspected or confirmed elevated ICP.
• To synthesize existing guidelines and expert recommendations into core management principles.

Main Methods:

• Review of invasive and noninvasive diagnostic methods, including patient history, physical examination, neuroimaging, and ICP monitoring.
• Synthesis of current treatment guidelines and expert consensus statements.
• Identification of core management principles for acute elevated ICP.

Main Results:

• Exploration of diagnostic utilities for elevated ICP.
• Identification of key management strategies including noninvasive maneuvers, neuroprotective intubation/ventilation, and pharmacologic agents.
• Emphasis on an empirical approach for time-sensitive presentations.

Conclusions:

• An organized, evidence-based approach is crucial for managing acute elevated ICP.
• A combination of diagnostic methods and core management principles can guide initial resuscitation efforts.
• This review provides a framework for empirical management of elevated ICP in the early stages of critical illness.
