Comparability of Bispectral Index and NeuroSENSE in Aged Patients

Comparability of Bispectral Index and NeuroSENSE in Aged Patients

The assessment of anesthesia depth was based, until recently, on the evolution of hemodynamic parameters. Nowadays it can be evaluated by several monitoring methods, derived from electroencephalogram analysis, namely the Bispectral Index (Aspect Medical Systems, Newton, USA). A new modality is currently under development: the NeuroSENSE (Cleveland Medical Devices Inc., Cleveland, OH 44103, USA).

Use of such devices is discussed in aged patients. The purpose of this study is to compare Bispectral Index and NeuroSENSE during awake periods and during natural sleep.

Inclusion Criteria:

• patients older than 74 years

Exclusion Criteria:

• pace-maker
