Outcome Measures

Primary Outcomes (1)

  • Intracranial Pressure (ICP) >25mmHg

    Accuracy of ONSD measurement (index test) compared to the reference standard- ICP\>25mmHg on concomitant invasive monitoring

    Days 1-7

Secondary Outcomes (3)

  • Therapeutic Intensity Level (TIL)

    Assessed at time of discharge from the neurotrauma intensive care unit- Average expected to be about 7 days

  • In-Hospital Mortality

    At Discharge from inpatient admission- Average expected to be about 30 days

  • Poor functional outcome at discharge- Glasgow Outcome Scale <4

    At Discharge from inpatient admission- Average expected to be about 30 days

Study Arms (1)

Optic nerve ultrasound

Optic nerve sheath diameter (ONSD) measurement will be performed in subjects with concomitant measurement of Intracranial Pressure (ICP) from an invasive ICP monitor. The operator measuring ONSD will be blinded to concomitant ICP.

Device: Optic nerve ultrasound

Interventions

Measurement of ONSD with concomitant invasive ICP measurement will be performed at enrollment and at least daily for a total of 7 days. Additional measurements of ONSD may be performed at any time following any decline in Glasgow Coma Scale (GCS) score by 2+ points during the 7 day period.
