Psychometric Measurements of Three Nociception Assessments Methods in Intubated Brain Injured Critical Care Patients

Nociception in intensive care unit is frequently evaluated with some tools such as BPS (Behavioral Pain scale) and NCS (Nociception coma scale). These scales were not validated in intubated and brain injured ICU patients. The investigators propose to validate the NCS adapted for intubated patients (NCS-I) in comparison with the recommended scale (BPS) and the Pupillary response (videopupillometry) to noxious stimulation (common procedure of care).
