Randomized Controlled TrialPsychomotor Recovery Following Remimazolam-induced Sedation and the Effectiveness of Flumazenil as an Antidote.
Remimazolam tosylate (HR-7056) is a novel ester-type benzodiazepine with ultrafast onset of effect. The compound is being developed for sedation induction and maintenance during anesthesia. It was approved for procedural anesthesia in December 2019 by the National Medical Products Administration of China. Previous studies have reported on remimazolam's effects on consciousness and cognition. Although the time to full psychomotor recovery after remimazolam-mediated sedation is critical for decisions regarding hospital discharge, relevant clinical evidence is still lacking. This study investigated the residual psychomotor effects of remimazolam and their recovery from sedating treatment in 2 simulated clinical settings: (1) single-dose administration for sedation initiation; and (2) constant rate infusion for sedation maintenance. ⋯ The study results showed quicker psychomotor recovery from sedation in the remimazolam-treated group. The moderate and short-lasting residual effect of remimazolam after 2-h conscious sedation proposes a need for psychomotor assessment(s) before hospital discharge.
