Objective To analyze the clinical and nursing effects of low-dose dexmedetomidine in the prevention of delirium during recovery from general anesthesia in elderly patients. Methods 80 elderly patients undergoing general anesthesia surgery in our hospital from January 2021 to December 2021 were selected and randomly divided into groups. The dexmedetomidine group was given low-dose dexmedetomidine, and the control group was given low-dose dexmedetomidine during anesthesia induction. The same volume of normal saline was injected intravenously before, and the incidence of delirium, visual analog score, agitation score, excellent and good rate of anesthesia, mean arterial pressure at different time, and ventricular rate were compared between the two groups. Results The dexmedetomidine group had a lower incidence of postoperative delirium, a lower visual analog score and agitation score, a lower ventricular rate at different times, and a lower mean arterial pressure than the control group. P <0.05. Conclusion Dexmedetomidine has an accurate anesthesia effect on elderly patients undergoing general anesthesia, can maintain the stability of vital signs during surgery, and reduce postoperative delirium during recovery, which is worthy of promotion.
