Clinical Trial 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).

Intervention

Device:
• Transcranial Doppler

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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
Primary	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
