Intracranial pressure (ICP) monitoring has long anchored neurocritical care, with continuous recording dating to Lundberg’s work in the 1960s. In traumatic brain injury (TBI), elevated ICP compromises brain health through reduced cerebral perfusion pressure and ischemia, distortion from mass effect, and risks of herniation, neurodevastation, or death if not managed.

Current Brain Trauma Foundation guidelines advise ICP monitoring for all patients with severe TBI, defined by a Glasgow Coma Scale score of 8 or lower, and ICP-directed therapy remains central to contemporary TBI protocols. Despite widespread use, several critical questions persist.

What ICP level should prompt treatment escalation remains uncertain, and whether optimal thresholds vary with age is unclear. The potential benefit of individualizing ICP targets instead of applying universal values has not been definitively established.

Additionally, criteria for selecting patients for monitoring are debated, a consideration that is particularly salient in pediatrics given developing brains and the lifelong implications of treatment decisions.

Clinical Editorial

Context and purpose

The report revisits ICP monitoring as a longstanding element of neurocritical care since early ICU work with external ventricular drains.
In traumatic brain injury, elevated ICP poses risks through diminished cerebral perfusion, structural distortion, and potential herniation or death if not addressed.

Study scope and design emphasis

The discussion centers on determining the ICP value that should prompt escalation of therapy.
It foregrounds the possibility that thresholds may differ by age and that universal targets might not suit all patients, highlighting the potential need for individualized targets.

Population and clinical relevance

The focus is on pediatric populations, where brain development could influence injury response and treatment impact.
The text notes that guidelines from major authorities advocate ICP-directed management for severe pediatric TBI, yet optimal triggers remain uncertain.

Gaps and uncertainty

The content explicitly calls into question whether current universal thresholds are appropriate for children and emphasizes questions about monitoring eligibility and personalized targets.
