Summary

The purpose of this study is to determine the prevalence of brainstem dysfunction in critically ill ventilated and deeply sedated patients hospitalized in the Intensive Care Unit (ICU) for a SARS-CoV-s2 infection.

Conditions

Interventions

DIAGNOSTIC_TEST

Brainstem Responses Assessment Sedation Score (BRASS)

It consists of a standardized evaluation of brainstem reflexes with a score of 1 attributed for absence of pupillary light reflex, cough reflex and the combined absence of grimace and oculocephalic reflex, a score of 2 for absent corneal reflex and a score of 3 for absent grimace in the presence of oculocephalic The resulting sum ranges from 0 to 7. It will be performed at two times points: a first time under sedation and a second time 3 to 5 days after sedation weaning.

DIAGNOSTIC_TEST

Electroencephalogram with EKG lead

A 20 minutes clinical (12 electrodes) EEG with an EKG lead will be performed a first time under sedation and a second time 3 to 5 days after sedation weaning. These EEG recordings will allow to measure the sympathic-parasympathetic ratio using spectral analysis of the EKG and also to measure quantitative markers of brain EEG activity (spectral power and connectivity in delta, theta, alpha, beta and gamma band; complexity).
