Reliability of BIS Monitoring in Neurosurgical Patients

Completed
Conditions
Sovra and Intra Tentorial Lesions
Interventions
Device: Bispectral Index (BIS Vista, Covidien)
Registration Number
NCT01483547
Lead Sponsor
Fondazione I.R.C.C.S. Istituto Neurologico Carlo Besta
Brief Summary

The aim of the study is to assess the reliability of Bispectral Index (BIS Vista , Covidien) in neurosurgical patients . BIS values at Loss of Consciousness (LOC), Post Intubation (PI) and Return of Consciousness (ROC) in neurosurgical patients are compared to those of non-neurosurgical patients, during routine anesthesia procedures.
