Research is being conducted on the effective doses of remimazolam and esketamine, often in combination with other medications, for various medical procedures. The focus includes their use for endotracheal intubation in pediatric patients without muscle relaxants, as well as for procedures like gastroscopy and hysteroscopy. Studies are also exploring the efficacy and safety of remimazolam compared to other anesthetics, such as propofol, in different patient populations.
