Résumé
Objective To investigate the influence of pre-administration of flurbiprofen on the hyperalgesia after remifentanil anesthesia.Methods This study included a total of 96 patients with abdominal surgery in the department of general surgery of our hospital.According to the random number table method,they were divided into 4 groups (n =24).Flurbiprofen axetil 1.5 mg/kg was injected intravenously before anesthesia in groups A1 and A2,flurbiprofen axetil was not injected in-travenously before anesthesia in groups B1 and B2.Anesthesia was maintained with infusion of remifentanil 0.1 μg·kg-1 ·min-1 in groups A1 and B1 0.4 μg·kg-1 ·min-1 in groups A2 and B2. The spontaneous breathing recovery time, consciousness recovery time,extubation time and anesthesia recover period of nausea,vomiting,restlessness and pain VAS scores were recorded. Results There was no significant difference in breath recovery time,consciousness recovery time and extubation time between the four groups.VAS score (9.0±1.8)was the highest in group B2,VAS score was significantly higher than the other three groups (P <0.05).VAS score (3.1±1.1)was the lowest in group A1, which was significantly lower than the other three groups (P < 0.05 ). Conclusion Pre-application of flurbiprofen 1.5 mg/kg can reduce postoperative hyperalgesia after remifentanil anesthesia in patients undergoing abdominal surgery.
