Perioperative Pain Management Of Arthroscopic Knee Surgery Under Local Anesthesia

Objective:To study the perioperative analgesic efficacy and interaction effect of ropivacaine and furbiprofen axetil during arthroscopy knee joint under local anesthesia.Method:Seventy-two patients who were to undergo arthroscopy knee joint operation under local anesthesia were randomized into group P(placebo), group F(furbiprofen axetil),group R(repivacaine) and group C(combined furbiprofen axetil and repivacaine). Visual analogue scale(VAS), incidence of side effects, dosage and time of supplementary tramadol and satisfaction degree of patients were compared during and 1,2,4,8,12 and 24h after operation to evaluate their pain control effect in different groups.Result:Furbiprofen axetil and repivacaine effectively controlled the pain and exhibited a synergic effect 2 and 4h after operation. However, only furbiprofen axetil could effectively control the pain at rest and exercise 8h after operation. No difference was found in VAS among different groups 1,12 and 24h after operation, but a significant difference was observed during radiofrequency between group P and group F(P=0.015).Conclusion:Furbiprofen axetil can effectively reduce perioperative pain score. Repivacaine has a rather good analgesic effect early after operation. Furbiprofen axetil combined with repivacaine has a synergic effect and is an excellent protocol of arthroscopic knee surgery under local anesthesia.
