Study on the efficacy and safety of dezocine applicated in postoperative analgesia for elderly patients

Objective To investigate the efficacy and safety of dezocine applicated in postoperative analgesia for elderly patients. Methods 50 elderly patients with elective cholecystectomy were selected as the research object, and they were randomly divided into the study group and control group. The control group patients took sufentanil+ tropisetron treatment, while the study group took sufentanil+ dezocine+ tropisetron treatment. The postoperative analgesia sedation score, adverse reaction of the two groups were observed and recorded, and the contrast analysis was carried on. Results There was no significant difference in comparison of postoperative analgesia sedation score of the two groups(P> 0.05); The incidence of adverse reaction of the study group was 12%, which was significantly lower than 40% of the control group(χ2= 20.37,P<0.01). Conclusion Dezocine for postoperative elderly patients has obvious effect, postoperative analgesia and sedation, and high safety, which is worthy of reference.
