Effects of transcutaneous electrical acupoint stimulation combined with multimodal analgesia on early active pain and resting pain after total knee arthroplasty
Objective To explore the effects of transcutaneous electrical acupoint stimulation(TEAS)combined with multimodal analgesia on early active and resting pain after total knee arthroplasty(TKA).Methods A total of 68 patients with TKA were randomly divided into treatment group and control group,34 cases in each one.The control group was treated with multimodal analgesia,and the treatment group was treated with TEAS based on multimodal analgesia.The clinical and blood test indexes of 2 groups were recorded and analyzed.Results On the 3rd,7th,10th and 14th day after operation,the active pain scores of the treatment group were lower than those of the control group(P＜0.01,P＜0.05).On the 1st day after operation,the active pain scores of the two groups were higher than those before operation(P＜0.01),and on the 3rd,7th,10th and 14th day after operation,the active pain scores of the two groups were lower than those before operation(P＜0.01).The rest pain scores of the treatment group were lower than those of the control group on 7th and 10th day after operation(P＜0.05).On the 1st and 3rd day after operation,the resting pain scores of the treatment group were higher than those before operation(P＜0.05),and on the 7th,10th and 14th day after operation,there was no significant difference between preoperative and postoperative scores in the treatment group(P＞0.05).On the 1st,3rd,7th and 10th day after operation,the resting pain scores of the control group were higher than those before operation(P＜0.05),and on the 14th day after operation,there was no significant difference in the scores before and after operation of the control group(P＞0.05).The temperature of the operated knee in the treatment group was lower than that in the control group on the 14th day after operation(P＜0.01),and the diameter of suprapatellar circumference was smaller than that of the control group(P＜0.01).The level of serum CRP in the treatment group were lower than that in the control group on the 7th and 14th day after operation(P＜0.01,P＜0.05).Conclusion TEAS combined with multimodal analgesia can reduce the temperature of the knee joint after TKA,accelerate limb swelling resolution,promote the resolution of inflammation.TEAS can relieve early active pain and resting pain after TKA,and the relief effect on active pain is more significant than that on resting pain.
