| Objective: Postoperative analgesia is an important factor affecting the postoperative recovery of patients undergoing total knee arthroplasty.This study aims to explore transcutaneous electrical acupoint stimulation(Transcutaneous Electrical Acupoint Stimulation,TEAS)The auxiliary analgesic effect for patients after total knee arthroplasty,in order to improve the postoperative rehabilitation process.Methods: Random selection July 2020 to January 2021 at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine.Joint Orthopedics Patients Undergoing Unilateral Total Knee Arthroplasty 90 cases,American Society of Anesthesiologists classification standards(American Society Anesthesiologist,ASA)I to III grade,according to random number table divided into T group(treatment group,n=40)and C group(control group,n=50),all patients use subarachnoid space and dura mater external combined block + femoral plexus block anesthesia,postoperative patient controlled intravenous analgesia(PCA)pump to maintain postoperative 48 hour continuous analgesia;routine use the nonsteroidal anti inflammatory analgesic celecoxib 0.2g BID for anti inflammatory and swelling.According to the theory of《Acupuncture and Moxibustion》select the points of Neiguan,Hegu,and Shenmen on the upper limbs of the patients in the first 1-7 days after the operation,and the contralateral side of the lower limbs Xuanzhong,Perform transcutaneous electrical stimulation at Zusanli and Sanyinjiao points,the waveform adopts sparsedense waves,and the frequency adopts 2-100 Hz,the intensity is for the patient to sense the acupuncture sensation of soreness,numbness and pain,about5 m A up and down,continuous 30 min.Use the visual analogue scale method(VAS)to record the postoperative first 1d,2d,3d,5d,7d resting time of the two groups of patients VAS score(Resting Pain Score)and post operatively 3d,5d,7d rehabilitation VAS score(Sports Pain Score),48 hours Internal PCA the total number of compression and the usage rate of intravenous non steroidal anti inflammatory drugs and opioids in 7 days except for regular oral analgesia.Use Excel2010 software for data collection and use SPSS25.0 for statistical analysis and production of statistical charts.Results: Patients whose observation indicators were finally collected 86 cases(T group 37 cases,C group 49 cases),but among them 24 cases(T group 6 cases,C group18 cases)were excluded due to accidental selfadministration of other analgesics.Surplus capital observed cases with complete materials 62 cases(T group 31 cases,C group 31 cases)were included in statistical processing.Compare the two groups patients on age,gender,surgical site(left or right)and operation duration,the difference is not statistically significant(P >0.05),There was no statistically significant difference in the 1d,5d,7d VAS scores between the two groups in the resting state(P >0.05)the scores of 2d,3d after operation T group score is lower than C group(P <0.05);2d of VAS score T group is significantly lower than C group(P=0.001);in the state of rehabilitation training activities of the two groups after the first 3d VAS score T group is lower than C group(P <0.05);postoperative 5d,7d VAS score difference is not statistically significant(P >0.05);Postoperatively 48 h PCA Pressing times T group was significantly lower than C group(P<0.01);two groups of patients postoperative voluntary additional analgesic use rate T Group is lower than C Group(P<0.05).Conclusion: TEAS used for patients after total knee arthroplasty has obvious auxiliary analgesic effect,can improve resting rest pain and exercise pain,and reduce nonsteroidal antiinflammatory drugs and opioids in patients after total knee arthroplasty The application of similar drugs. |
