Brief summary
The purpose of this study is to determine the overall optimal timing of when the Bispectral Index (BIS) monitor should be started: before or after the muscle relaxant is given.
Interventions
DEVICEBispectral Index (BIS) monitoring system
Left and right sensors to record EEG activity and muscle reaction to anesthesia utilized in the operating room by anesthesia providers to assess the depth of sedation in patients with anesthesia.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| BIS Values | 25-minute period in the operating room | Parameters measured from both left and right BIS sensors. BIS monitor algorithm to process EEG information second by second and outputs a number (0-100) that corresponds with a patient's level of consciousness. A level of 0 indicates no EEG activity; a level of 100 indicates awake EEG activity. |
