ABSTRACT

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.

ABSTRACT

Objective To investigate the effect of ketamine on the cGMP content in cerebral cortex, hypothalamus and brain stem in a rat model of CFA-induced arthritis. Methods Twenty-four SD rats weighing 200-220 g were randomly divided into three groups with 8 animals in each group, group Ⅰ: normal rat + intraperitoneal normal saline (ip NS);group Ⅱ : arthritic rat+ ip NS;group Ⅲ: arthritic rat + ip ketamine 100mg?kg-1 . Arthritis was produced by injecting CFA 0.05 ml into left ankle joint which developed inflammatory response within 24h and became hyperalgesic. The hyperalgesia persisted for more than 6 weeks. Three days after the arthritis model was established, paw withdrawal latency (PWL) to radiant heat was measured. 15 min after ip ketamine the animals were decapitated and cerebral cortex, hypothalamus and brain stem were separately isolated for determination of cGMP content using radioimmunoassay. Results In arthritic rats the PWL was significantly shortert (6.7 ? 1.2)s] than that in the normai rats [(12.5?1.9)s] ( P
