Abstract: Objective To observe the effects of low-dose nalmefene on the postoperative analgesia and side effects of sufentanil and dezocine.Methods Eighty elder patients undergoing hip operations under spinal anesthesia (SA) and given patient-controlled intravenous analgesia(PCIA) were randomly divided into two groups (n=40 each group).Group T was given sufentanil and dezocine plus tropisetron for PCIA, group N was given sufentanil and dezocine plus low-dose nalmefene.The Visual Analogue Scale(VAS) pain scores of two groups were assessed at 2h, 4h, 8h, 12h, 24h, 48h after operation.The side effects and pressing times of PCA were observed and recorded as well.Results The VAS scores in the group N were statistically lower than that of group T postoperatively (P<0.05).The pressing times of PCA in group N was less than that in group T(P<0.05).The incidence of nausea and vomiting, dizziness in group N was significantly lower than group T (P<0.05).There was no occurrence of drowsiness and respiratory depression in group N, but no statistical significance compared with group T.Conclusion Compared with tropisetron, low-dose nalmefene can enhance the analgesic effect safely and reduce the incidence of side effects of sufentanil and dezocine to some extent in elder patients.
