Effect and Mechanism of Remimazolam Benzenesulfonate on Enhanced Recovery After Surgery in Patients Undergoing Radical Gastrectomy for Gastric Cancer

"In the experimental group, remazolam 6-12mg/kg/h, atracurium cisphenylate 0.1-0.3 mg/kg and sufentanil 0.3-0.5 μg/kg were infused by micropump for anesthesia induction, and the BIS value was controlled at 50±5 before tracheal intubation.~Anesthesia maintenance: intravenous infusion of remifentanil 0.1-0.3 μg/kg/min, target controlled infusion of remifentanil in experimental group (group R), BIS value was controlled at 50±5, intermittent addition of atracurium cisphenylate to maintain muscle relaxation."
