简要总结
To observe the effect of intraoperative dexmedetomidine on the incidence of postoperative delirium, postoperative analgesic drug requirements and pain scores in elderly patients undergoing major abdominal surgery.
详细描述
This study is a multicenter, randomized, double-blind, placebo-controlled trial. Three hundred patients undergoing elective major abdominal surgery were randomized to the intervention and control groups. Patients in the intervention group were given a loading dose of 0.6 μg/kg of dexmedetomidine by intravenous infusion within 10 minutes after intubation, followed by a continuous infusion at a rate of 0.4 μg/kg/h until 30 min before the end of the procedure; patients in the control group were given an equal volume of saline. Data were collected at 1-5 days and 1 month postoperative follow-up.
