The Clinical Observation On The Effects Of Traditional Chinese Medicine Combined Femoral Nerve Block In Analgesia And Early Functional Recovery After Artificial Total Knee Arthroplasty

Objective:To explore the clinical efficacy and application value of multimodal analgesia centered on the combination of traditional Chinese medicine and femoral nerve block for postoperative analgesia and early functional recovery after total knee arthroplasty.It is hoped that this study can provide some theoretical basis for postoperative analgesia and rapid rehabilitation of patients after TKA.Methods:A total of 80 patients that suffered from limb pain after receiving the first unilateral TKA in Articular Orthopedics,the First Affiliated Hospital of Shandong University of Traditional Chinese Medicine for Pure Knee Osteoarthritis from July 2016 to February 2018 and met the inclusion criteria were selected.Patients were randomly divided into observation group,control group 1,control group 2 and control group 3,20 cases in each group.The control group 1 used postoperative routine treatment scheme of Articular Orthopedics,Quyu Tongluo decoction(a dose per day,take it in the morning and evening)was administered to the control group 2 on the second day after operation,based on the treatment of the control group 1,taking 6 consecutive days.The control group 3 was given single femoral nerve block after operation,based on the treatment of the control group 1.The observation group was given the combination of Quyu Tongluo decoction and single femoral nerve block.HSS knee function scores of four groups were observed and recorded before surgery and on the 3rd and 7th day after surgery.VAS pain scores of four groups during activity and rest were measured and recorded respectively on the12 h,1st,3rd,5th and 7th day after surgery.Results:1.There was no significant difference(P>0.05)in preoperative HSS function score between the four groups.There was a significant difference(P>0.05)in the HSS score observed on the 3rd day after the surgery between the observation group and the control group 1、2,and the observation group was better than the control group 1 and the control group 2.There was no statistical difference(P>0.05)between the observation group and the control group 3.On the 7th day after the surgery,the HSS score was significantly different(P<0.05)between the observation group and the control group 1、2、3,and the observation group was better than the other 3 groups.2.On the 12 h,1st day and 3rd day after operation,the VAS pain scores of activity and rest were significantly different(P<0.05)between the observation group and the control group 1、2,and the observation group was better than the control group 1 and the control group 2.There was no statistical difference(P>0.05)between the observation group and the control group 3.On the 5th,7th day after operation,the VAS pain scores of activity and rest were significantly different(P>0.05)between the observation group and the control group 1、2、3,and the observation group was better than the other 3 groups.Conclusion:The multimodal analgesia centered on the combination of traditional Chinese medicine and femoral nerve block has significant clinical effect on postoperative analgesia after total knee arthroplasty,which promotes early functional recovery,shortens hospitalization and rehabilitation time,and can be applied in clinical practice.
