Trial Outcomes & Findings for EEG Studies of Sevoflurane-Induced General Anesthesia (NCT NCT03503578)

NCT ID: NCT03503578

Last Updated: 2019-10-24

Results Overview

Changes in power from baseline at various EEG spectral frequencies were assessed at sevoflurane-induced loss of responsiveness. EEGs of 12 patients were analyzed to determine changes in various EEG spectral frequencies (alpha, theta, delta, etc.) from baseline. The outcome measure reflects the associated frequency (Hz) at which changes were found under sevoflurane-induced general anesthesia. These frequency values are a representation of the findings for all 12 participants.
