Intracranial compliance monitoring using pulse shape index in traumatic brain injury: relation to cerebral physiology and clinical outcome

Crit CarePublished Retrospective cohort study

Authors' conclusion

PSI was linked to established indicators of intracranial compliance and provided early warning of impending intracranial hypertension. While PSI showed univariable associations with outcome, these did not remain in multivariable models.

Study context

Population
Traumatic brain injury (TBI) patients with ≥ 12 h of intracranial pressure (ICP)/pulse shape index (PSI) monitoring
Participants
321 patients
Outcome
Relation of PSI (artificial intelligence (AI)-based ICP pulse shape index, 1 normal to 4 disturbed) to markers of intracranial compliance, risk of ICP crisis and clinical outcome

Main finding

As reported in the abstract

PSI during the preceding hour predicted increased ICP burden above 20 mmHg (marginal R2)

≈30%

Observational data: associations, not effects.
