Brief Summary

Post-thyroidectomy pain is a prevalent early postoperative complication. While pharmacological agents remain the mainstay of analgesia, their clinical application is constrained by adverse effects including nausea, respiratory depression, and gastrointestinal disturbances. Transcutaneous electrical nerve stimulation based on wrist-ankle acupuncture theory (TENS-WAA) is a non-invasive analgesic modality that has demonstrated preliminary benefits in multiple pain scenarios. Nevertheless, robust evidence for its efficacy in post-thyroidectomy pain management is still lacking, limited by single-center designs and small sample sizes in existing studies. This trial aims to evaluate the efficacy and safety of TENS-WAA for pain control after thyroidectomy. The findings are expected to support a standardized non-pharmacological analgesic option as an adjunct to multimodal postoperative pain regimens, aligning with Enhanced Recovery After Surgery (ERAS) principles.

Outcome Measures

Primary Outcomes (1)

  • Pain VAS score

    VAS (Visual Analogue Scale) scoring, namely visual analogue scoring, usually employs a straight line or ruler 10 centimeters long, with0 representing the "no pain end" and 10 representing the "most intense pain". The patient marks on the straight line according to the level of pain he or she, to indicate the intensity of pain and the degree of unpleasant psychological experience. The higher the VAS score, the more painful it is. 0 points: no pain; -3 points: mild pain; 4-6 points: moderate pain; 7-9 severe pain; 10 points: unbearable pain, namely severe pain

    Evaluation time: 1) the subject returned to the ward after surgery; 2) immediately after electrical stimulation; 3) Postoperative 2 hours、Postoperative 3 hours、Postoperative 4 hours、Postoperative 9 hours、Postoperative 15 hours、Postoperative 24 hours

Secondary Outcomes (4)

  • PONV classification

    Postoperative 3 hours、Postoperative 9 hours、Postoperative 15 hours、Postoperative 24 hours

  • 40-item Quality of Recovery (QoR-40) score

    Postoperative 24 hours

  • Pain-related measures

    8.00 am on the morning after the operation

  • Safety indicators

    Postoperative 24 hours

Interventions

1. The time selection of acupoint treatment is to return to the ward immediately,2 and 4 hours after surgery; 2. Time of each stimulation: 30min; 3. Acupoint extraction: According to the theory of wrist and ankle acupuncture and the location of pain, the upper 1 area (the ulnar margin on the little finger side and the depression of the flexor carpi ulnaris tendon) and the upper 2 area (between the palmaris longus tendon and the flexor carpi radialis on both sides) on the affected side (bilateral for total thyroidectomy) were selected as the intervention site, and the upper and lower parallel electrodes were placed in each area, and a total of 4 electrodes (8 electrodes on both sides) were placed. 4. The parameter setting of the equipment: the frequency is set to 2Hz, the pulse width is set to 250μs, continuous wave is used, and the current intensity is the maximum tolerance of the subject's small pain threshold for 30min.
