Combination of Entropy and Electroencephalograpy for Deep of Hypnosis Monitoring Improvement during General Anesthesia

Abstract

Background: Deep of hypnosis monitoring based on electroencephalogram (EEG) and end tidal anesthetic concentration (ETAC) of volatile agents are a standard of care in patients under general anesthesia. Entropy and ETAC could reflected the effects of volatile agents as evidence had been showed, but its accuracy for hypnosis monitoring during nociceptive stimulation in patients under neuromuscular block and emergence is controversial.
