Breast Surgery
Conditions
Brief summary
This is a prospective, observational study, aimed to establish changes of bispectral bilateral system in both cerebral hemispheres during a total intravenous anaesthesia during breast surgery in the woman. By placing two Bispectral bilateral sensors (BIS), one on both frontal lobes, and another on both parietal lobes, we wanted to evaluate differences between frontal and parietal areas, when the patient is awake and during the anaesthetic procedure.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Bilateral BIS values from frontal and parietal areas. | Bilateral BIS values will be taken at baseline, anaesthetic induction, endotracheal intubation, skin incision, mantenance of anaesthesia and in emergence from anaesthesia ( 3 hours as a maximum from baseline to emergence). |
Secondary
| Measure | Time frame |
|---|---|
| EEG changes at LOC (loss of consciousness) and ROC (recovery of consciousness). | Changes will be evaluated at induction and emergence. |
