Effect of TEAS-assisted multimodal analgesia on postoperative recovery after total knee arthroplasty in elderly

OBJECTIVE: To explore the effect of transcutaneous electrical acupoint stimulation (TEAS) combined with traditional multimodal analgesia regimen on the postoperative recovery of elderly patients undergoing total knee arthroplasty (TKA). METHODS: Selected elective surgeries in our hospital from December 2018 to October 2019 Ninety elderly patients with unilateral TKA were divided into the TEAS group (T group, 45 cases) and the control group (C group, 45 cases) using the random number table. TEAS was performed at Sanli point, starting from 30 minutes before anesthesia to the end of skin suturing; Group C attached electrode pads to the same acupoints and connected the electrical stimulator, but no electrical stimulation was given. Patients in the two groups were observed at 6 h, 12 h, and 24 h after surgery and 36 h resting pain visual analogue (VAS) score; first ambulation time and VAS score; use of analgesic pumps and occurrence of nausea and vomiting within 48 h after surgery, as well as 15 items of recovery quality 48 h after surgery (QoR-15) score. RESULTS: The VAS score at rest 36 hours after surgery, the time to first ambulation and VAS score, the number of manual compressions by the analgesic pump and the total number of compressions, and the incidence of nausea and vomiting in group T were all significantly lower than those in group C. group, the difference was statistically significant (P<0.05); the QoR-15 score of group T 48 h after surgery was higher than that of group C, the difference was statistically significant (P<0.05). Patients in group 2 had statistically significant differences at 6 h, 12 h and There was no statistically significant difference in VAS scores at 24 h resting time (P>0.05). CONCLUSION: TEAS combined with traditional multimodal analgesia regimen can enhance the perioperative analgesia effect of TKA, reduce the occurrence of adverse reactions, and promote early postoperative Functional exercise and overall recovery quality accelerate the patient’s postoperative recovery.
