Brief Summary

Transcranial Doppler is performed daily in Intensive Care Unit in brain damaged patients. For a few years now, the measurement of the photomotor reflex by quantitative Pupillometry has been routinely performed in Intensive Care Units. The objective of this work is to see if Transcranial Doppler recorded parameters and Pupillary parameters are correlated to the neurological prognosis evaluated at 9 months by the Modified Rankin Score (mRS) and the Glasgow Outcome Scale Extended (GOS-E).

Outcome Measures

Primary Outcomes (2)

  • Modified Rankin Score (mRS) (0-5)

    Modified Rankin Score (mRS) measures the degree of disability following a stroke in a patient (level 0 for patients with no symptoms to level 5 for patients with major disability and total dependency)..

    Year: 1

  • Glasgow Outcome Scale Extended (GOS-E) (1-8)

    Glasgow Outcome Scale Extended (GOS-E) measure the impact of brain injured (minimum at 1 (Dead) and maximum at 8 (Upper Good Recovery).

    Year: 1

Secondary Outcomes (14)

  • Mean Systolic Velocity (VMS)

    At inclusion

  • Intra-Cranial Pressure (ICP)

    At inclusion

  • Pulsatility Index (PI)

    At inclusion

  • Tele-Diastolic Velocity (TDV)

    At inclusion

  • Basic pupil diameter

    At inclusion

  • +9 more secondary outcomes

Study Arms (1)

brain damaged patients

All major brain damaged patients (stroke or head trauma) admitted to reanimation will be included. In the usual practice, they have a Transcranial Doppler and the measurement of the photomotor reflex by quantitative Pupillometry. It is planned to collect the simultaneous values of the different parameters during 2,000 measurements. The data will be collected retrospectively from 01/12/2020, and prospectively from 01/04/2021.

Device: Transcranial DopplerDevice: Pupillometry.

Interventions

This device measures Mean Systolic Velocity (VMS), Tele-Diastolic Velocity (TDV) and Pulsatility Index (PI),

brain damaged patients

This device measures the photomotor reflex (basic pupil diameter, percentage of variation, latent and slope of the standard photomotor reflex)
