The Application of Electrical Stimulation in Postoperative Pain Management of Thyroid Surgery

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.
