NCT05740735

Brief Summary

The purpose of this study is to determine if the use of emotional sound as subject own name (SON) pronounced by a familiar voice (FV) compared to SON pronounced by a non-familiar voice (NFV) during event related potential (ERP) produced a more reliable neurophysiological P300 responses, and to assess the prognostic value of this P300 responses induced by the SON with a FV.

    Month 3

Secondary Outcomes (19)

  • Richmond Agitation-Sedation Scale

    Day 14

  • Coma recovery scale-revised CRS-r

    Day 7

  • +14 more secondary outcomes

Study Arms (2)

Disorder of consciousness patients - Prospective group

DOC defined either by a coma (Glasgow Coma Scale \<8), a vegetative state (VS) or a minimal state of consciousness (MCS) according to the Coma recovery scale-revised (CRS-r) after a primary brain injury: severe traumatic brain injury (TBI)), subarachnoid hemorrhage, stroke or cardiac arrest (CA)

Other: Use of "expressive" sounds

Disorder of consciousness patients - Retrospective group

Other: Having benefited from a prognostic evaluation by event related potentials (without sound research methods, only neutral sounds)

Interventions

Use of "expressive" sounds, that is to say the own first name pronounced by the voice of the relative to generate the P300 and a sound with an "approaching" character of the subject to generate the MMN. The investigators will thus be able to compare: * MMN: present/absent for each modality (neutral vs approaching sounds) * Wave P3a: latencies and amplitudes for each modality (own first name voice of the near vs unfamiliar).

Disorder of consciousness patients - Prospective group

Retrospective inclusion Have already had an assessment with event related potentials without "emotional" modalities (VF and similar sounds) as part of their care between April 2022 and December 2022 in intensive care at Cochin hospital.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

All patients admitted to Cochin Hospital ICU with a primary brain injury (after CA, TBI, stroke) and a persistent DOC (coma, VS, MCS) 12 hours after sedation discontinuation.

You may qualify if:

  • patients hospitalized in ICU for cardiac arrest, stroke, subarachnoid haemorrhage or head trauma,
  • persistent disorder of consciousness (DoC) 12 hours after sedation weaning or patient who has benefited from a prognostic assessment for persistent DoC and who has had in this assessment an evaluation by late PEA with MMN and P300 responses only to neutral sounds ("beep" and patient's first name pronounced by an unfamiliar voice) there is more than 6 months (since April 2022)

You may not qualify if:

  • Moribund patient
  • Uncontrolled Shock during the neurophysiological evaluation
  • Sedated patient
  • Minor patient
  • brain death
  • Known deafness
  • Pregnant woman
  • Patient not affiliated to a social security system
  • Implementation of limitations and stop of active therapies
  • Patient under legal protection
  • Patient benefiting from State Medical Aid
