Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Expérimental: Toolbox: Automated group
Toolbox: Automated administration of intravenous anesthetic (propofol 1%) and analgesic (remifentanil, Ultiva(r)) guided by the Bispectral index through a controller with a previously described algorithm. Objective of depth anesthesia: 40-60 |
A dedicated algorithm controls the infusion rate of drugs depending on the magnitude of variation of the bispectral index
Autres noms:
|
|
Comparateur actif: Manual group
Manual administration of intravenous anesthetic (propofol 1%) and analgesic (remifentanil, Ultiva(r)) guided by the Bispectral index as usually performed in the operative theater. Objective of depth anesthesia: 40-60 |
The anesthesiologist controls the infusion rate of drugs depending of the magnitude of variation of the bispectral index

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|

Délai: 6 months
|
Disability is evaluated using the InterRai scale; a death is considered as an irreversible disability institutionalization is considered as a severe disability InterRai scale would discriminate other patients
