Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To explore the sedative effect of remimazolam in patients undergoing spinal anesthesia without pain stimulation. Both the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) and the Wavelet index (WLi) were used to monitor the depth of anesthesia of remimazolam, and exploring the correlation and consistency between MOAA/S score and WLi value at the same time.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients undergoing spinal anesthesia were received remimazolam besylate for sedation continuously. Both the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) and the Wavelet index (WLi) were used to monitor the depth of anesthesia of remimazolam, and exploring the correlation and consistency between MOAA/S score and WLi value at the same time.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Remimazolam group

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.

Intervention Type DRUG

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.
