Prediction of EEG-Derived Wavelet Index for End-Tidal Sevoflurane in Pediatric Anesthesia: A Prospective, Single-Blind Study.

Background: Processed electroencephalogram is able to assess the depth of anesthesia. EEG-derived wavelet index (WLi) is a novel indicator derived from EEG on the basis of wavelet analysis.

Aims: We primarily tested whether WLi can reflect changes in end-tidal sevoflurane (sevo) in pediatric patients, especially during the transition from awake status to 0.
