Study Summary

To investigate the relationship between BIS™ and inhaled anesthetics across a wide range of anesthetic concentration and hypnotic states, and to provide evidence to support BIS™ performance in use with Isoflurane, Sevoflurane and Desflurane in combination with opioids.

Primary Outcome

To determine BIS50, the BIS™ value (index score on a scale of 0-100 (0 being dead and 100 being fully awake/responsive) on the BIS™ monitor) at which 50% of patients will be unresponsive at a given drug concentration. Responsiveness is measured using the Modified Observer's Assessment of Alertness and Sedation (MOAAS) a 0-5 scale where 0 represents no response to deep stimulus and 5 represents fully awake).
