Comparison of Remimazolam versus Dexmedetomidine on Hemodynamics in Older Patients Under Lower Extremity Orthopedic Surgery with Spinal Anesthesia: A Randomized Controlled Trial

Remimazolam demonstrated superior hemodynamic stability and fewer adverse cardiovascular events than dexmedetomidine, along with reduced requirements for vasoactive medications, making it an alternative to intraoperative sedation in older patients undergoing lower limb surgery under spinal anesthesia.
