EEG ‐Derived Wavelet Index for Assessment of Procedural Sedation in Children Undergoing Magnetic Resonance Examination: A Diagnostic Study
Performance · Prediction of MRI sedation failureResult — go to the resultΔAUC 0.162 95% CI 0.004–0.329Authors' conclusion
WLI may provide an adjunctive, non-stimulating measure for risk stratification in pediatric MRI sedation
Study context
- Population
- Children undergoing MRI after procedural sedation with chloral hydrate and dexmedetomidine, tertiary care hospital9 sedation failures
- Participants
- 74 children
- Comparison
- Wavelet index (WLI) vs RS
- Outcome
- Discrimination of MRI sedation failure (AUC); success = planned MRI completed at first attempt without clinically significant motion artifact, rescue sedation or conversion to GA
