Prediction of EEG‐Derived Wavelet Index for End‐Tidal Sevoflurane in Pediatric Anesthesia: A Prospective, Single‐Blind Study
Authors' conclusion
WLi can reflect the transition of anesthesia status from light to moderate sedation, and the plateau effect might indicate adequate depth of anesthesia during deeper sedation and general anesthesia.
Study context
- Population
- Pediatric patients aged 6 months to 6 years undergoing elective surgery, sevoET maintained at 2.0, 1.3 and 0.6 age-adjusted MAC in stepwise decrements
- Participants
- 40 patients
- Comparison
- Wavelet index (WLi) vs BIS for tracking sevoET
- Outcome
- Whether WLi reflects changes in sevoET, especially transition from awake to 0.6 MAC
Methodological detailssingle-blind, single-centre
- Single-blind
- Single-centre
Performance
As reported in the abstract
Prediction of anesthesia status transitions
- WLi and BIS comparable in predicting transition from awake to 0.6 MAC and from 1.3 to 2.0 MAC
- WLi showed a plateau effect and failed to predict transition from 0.6 to 1.3 MAC, unlike BIS
Further findings
Concentration-effect relationship (EC50)
Effect of age on WLi
- WLi values between individuals independent of age
