Details and patient eligibility

About

At present, surgical resection remains one of the main methods for the radical treatment of lung cancer. Compared with traditional thoracotomy, Video-assisted Thoracoscopic Surgery (VATS) offers obvious advantages, such as less surgical trauma and rapid postoperative recovery. However, a certain proportion of patients will still experience moderate to severe pain after undergoing VATS. Postoperative acute pain can lead to increased postoperative pulmonary complications, prolonged hospital stays, and increased treatment costs. Additionally, it is also associated with the development of postoperative chronic pain. Therefore, effective pain management after VATS is crucial.

Researchers will compare Transcutaneous Electrical Nerve Stimulation (TENS) based on Wrist-Ankle Acupuncture theory (TENS-WAA) with a sham stimulation regimen to determine whether TENS-WAA can relieve postoperative pain in patients undergoing thoracoscopic lung resection. This study aims to enrich the existing postoperative analgesia schemes and provide a reliable basis for its clinical promotion.
