Due to the incomplete development of systems and low pain thresholds in the pediatric population, good general anesthesia is required during the perioperative period to ensure the smooth progress of the surgery.Propofol is often used for anesthesia induction in clinical work, which can achieve good anesthesia effects. However, this drug has obvious injection pain and is prone to significant inhibition of blood circulation, and may even lead to adverse conditions such as respiratory depression in children. For the pediatric population, maintaining appropriate anesthesia depth and stable circulation during the induction period of general anesthesia has always been a focus of attention and research by anesthesiologists.Remimazolam besylate is a new type of water-soluble ultra short acting benzodiazepine drug that is hydrolyzed and metabolized by plasma esterase in the body, independent of liver and kidney function, and the metabolite zolam propionic acid has no pharmacological activity; Rapid onset and failure, short sedation recovery time; Has little impact on respiration and circulation; And there is no injection pain.Remazolam besylate is highly suitable for children due to its characteristics, and some studies have demonstrated the safety of intravenous injection of Remazolam besylate. However, there is limited research on its dosage exploration, which to some extent limits its clinical application in children.This study aims to explore the 95% effective dose (ED95) of single intravenous injection of remidazolam besylate in children of different age groups, providing a theoretical basis for the use of remidazolam besylate in pediatric anesthesia.
