About

the investigators are conducting a clinical study on the efficacy and safety of remimazolam for induction and maintenance of anesthesia in elderly patients. Project number: CRCF-YXFN-202401029, funded by the Red Cross Foundation of China and will take more than 2 years to complete.

This is a single-center, randomized, controlled clinical study, randomized 60 elderly subjects undergoing general anesthesia for elective surgery. According to the random number method, propofol group (control group, group P) and remimazolam group (experimental group, group R), 30 cases in each group.

By participating in this study, it is possible to make anesthesia induction rapid and stable, stable intraoperative circulation, rapid recovery and safe and comfortable, reduce the Incidence of intraoperative awareness, arrhythmia, postoperative delusion, and so on, which is conducive to rapid postoperative recovery and reduce hospitalization costs.

Full description

Research background: Rapid and steady anesthesia induction, stable intraoperative circulation, rapid recovery, safe and comfortable, and few adverse reactions are the goals of anesthesiologists. Accelerating the surgical turnover and improving the efficiency are the clinical problems that need to be solved. Clinical general anesthesia often adopts static inhalation compound anesthesia to give full play to the advantages of intravenous and inhalation anesthesia and reduce their respective adverse reactions. Remimazolam, as a new ultra-short-acting benzodiazepine sedative, is not widely used in elderly patients, but its rapid onset, short time half-life, less accumulation, little cardiopulmonary inhibition, no injection pain, and can be antagonized by flumazenil, showing an irreplaceable advantage.

Study objective: To observe the efficacy and safety of remimazolam for the induction and maintenance of anesthesia in elderly patients, and to provide a new option for anesthesia management in elderly and critically ill patients.

Study method: This topic adopts a single-center, prospective, randomized, controlled research method, and expects to include 60 elderly subjects with general endotracheal anesthesia for elective surgery.
