Target Recruitment
36
Inclusion Criteria

- Healthy volunteers aged 18 to 70 years.
- No selection will be made regarding ethnic background.
- For this study no control group has been selected as EEG is compared between episodes rather than between individuals (each volunteer is his/her own control)
- We will select volunteers in order to obtain sufficient spread in the data concerning age and gender and location of the electrodes used
18-35 y 6 men / 6 women
35-50 y 6 men / 6 women
50-70 y 6 men / 6 women

Primary Outcome Measures
NameTimeMethod
Main Objective: To observe changes in cerebral activity as measured by EEG and clinical hypnotic and analgesic endpoints (=OAA/S score and response to tetanic stumulus) during administration of propofol or sevoflurane (with or without remifentanil) and to relate these effects to drug concentrations;Secondary Objective: All non-invasive vital sign parameters routinely used during anesthesia (cardiac, hemodynamic, respiratory and photo pleth data, inclusive the Rainbow Acoustic Monitor (Masimo, Irvine, CA, USA) will be related to both clinical and pharmacological endpoint;Primary end point(s): To observe changes in cerebral activity as measured by EEG and clinical hypnotic and analgesic endpoints (=OAA/S score and response to tetanic stumulus) during administration of propofol or sevoflurane (with or without remifentanil) and to relate these effects to drug concentrations;Timepoint(s) of evaluation of this end point: 2 years after the last inclusion
