RESUMO
Objective:To investigate the preemptive analgesic effect of flurbiprofen on inflammatory cytokine in patients undergoing cerebral operation.Methods:Forty ASA Ⅰ-Ⅱpatients undergoing cerebral surgery were randomly divided into control group(group C,n=20)and flurbiprofen group(group F,n=20).Flurbipmfen of 10 mL was given intravenously 15 min before skin incision.The values of VAS scores were recorded at 2 h,24 h and 48 h after operation.Blood samples were taken for determination of serum levels of TNF-α,IL-6 and IL-10 immediately before induction of anesthesia(T1,baseline),at 2 h of operation (T2),immediately after the end of operation (T3) and 24 h after operation (T4).The parameters of anaesthesia time,hemorrhage volume,urine volume,transfusion volume and the dosage of remifentanil and propofol were recorded during the period of anaesthesia.Results:The VAS score was lower in group F than that in group C at 2 h and 24 h after operation (P＜0.05),but there was no difference at 48 h after operation between the two groups(P＞0.05).The dosages of remifentanil and propofol were lower during anaesthesia in group F than that in group C(P＜0.05).Compared with T1,TNF-α was significantly increased at T2 and T3 in both groups,and the peak value at T2 (P＜0.05).TNF-α was decreased at T2-T4 in group F than that in group C(P＜0.05).Compared with T1,the levels of IL-6 and IL-10 were significantly increased at T2-T4 in both groups,and the peak value at T3(P＜O.05).The value of IL-6 was decreased and the value of IL-10 was increased at T2-T4 in group F than those in group C (P＜0.05).Conclusion:Flurbiprofen was suitable as a preemptive analgesia and could suppress stress reaction of inflammatory in neurosurgery.
