Application effect of dexmedetomidine combined with flurbiprofen axetil and flurbiprofen axetil monotherapy in radical operation of lung cancer and evaluation of the immune function.

To explore the effect of dexmedetomidine combined with flurbiprofen axetil on postoperative analgesia and immune function in patients with lung cancer after radical operation.60 lung cancer patients undergoing open chest radical surgery were selected and randomly divided into D & F Group (dexmedetomidine combined with flurbiprofen axetil) and F Group (flurbiprofen axetil), with 30 cases in each group. Before induction of general anesthesia, Group F was administered intravenous flurbiprofen axetil, and in D & F group, dexmedetomidine and erfuorbiprofen axetil were injected.At T2 (intubation) and T3 (extubation), map and HR in D & F group were significantly lower than those in F group (p<0.05). The extubation quality score of D & F group was significantly lower than that of F group (p<0.05). At 6 h and 12 h after operation, visual analogue scale (VAS) score and Bruggrmann comfort scale (BCS) score of D & F group were significantly lower than that of F group (p<0.05). The dosage of sufentanil and the times of pressing analgesia pump in group D & F were significantly less than those in group F (p<0.05). NK cells, CD3 + T cells and CD4 + / CD8 + in the D & F group were significantly higher than those in F group at 12h, 24h, 48 h and 1 week after operation (p<0.05).Flurbiprofen axetil can improve postoperative pain, but combined with dexmedetomidine better effect, postoperative comfort and immune function of patients were significantly improved.
