Clinical Study On Pain Control After Total Knee Arthroplasty By Transcutaneous Electrical Acupoint Stimulation Combined With Cocktail Therapy

Objective: To investigate the clinical effect of transcutaneous electrical acupoint stimulation combined with cocktail therapy on pain control after total knee arthroplasty,and to provide a theoretical reference for finding a safe and effective analgesia method after TKA.Methods: 60 patients with primary unilateral TKA due to knee osteoarthritis were randomly divided into three groups,20 patients in each group,control group A(oral celecoxib capsule),control group B(intraoperative local injection of " cocktail"),observation group C(percutaneous acupoint electrical stimulation combined with " cocktail" local injection).The VAS pain score,maximal voluntary flexion of knee joint,postoperative analgesia and adverse reactions were recorded in three groups after operation,and the data were statistically analyzed by SPSS17.0 software.Results: Resting state VAS pain score : group C were significantly lower than that of group A and group B at 12 h,24 h,48 h,72 h after surgery(P < 0.01),group B was lower than that of group A at 12 h,24 h,48 h after surgery(P < 0.05),the difference between group B and group A was not obvious at 72 h after operation(P > 0.05);The active state VAS pain score : group C was significantly lower than group A and group B at 24 h,48 h,72 h after surgery(P < 0.01),group B was lower than that of group A at 24 h,48 h after surgery(P < 0.05),the difference between group B and group A was not obvious at 72 h after operation(P > 0.05);The maximal voluntary flexion of knee joint: group C was significantly higher than that in group A and group B at 24 h,48h and 72 h after operation(P < 0.01).group B was higher than that in group A at 24 h,48h and 72 h after operation(P > 0.05).The number of additional analgesic drugs after operation in group C was significantly lower than that in group A and group B,and the incidence of adverse reaction in group C was significantly lower than that in group A and B(P < 0.05).There was no significant difference in the adverse reaction between group A and group B 72 hours after operation(P > 0.05).Conclusion: Transcutaneous electrical acupoint stimulation combined with cocktail therapy has obvious analgesic effect after total knee arthroplasty,and can significantly reduce the incidence of adverse reactions.It is a reliable,safe and noninvasive new method of postoperative analgesia for TKA,which is worthy of clinical application.
