The Effect of Wavelet Index in Monitoring the Sedation Depth of Remimazolam Besylate

Thirty patients underwent elective lower extremity surgery receive spinal anesthesia, and then remimazolam besylate was given intravenously with an induction dose of 3mg/min. When the MOAA/S (Modified Observer's Assessment of Alertness/Sedation) score was ≤1, remimazolam besylate was maintained at 1mg/min for 24min, and finally stopped. Wavelet index, MOAA/S score, blood pressure, heart rate, respiratory rate, and pulse oxygen saturation were continuously monitored during the period.
