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.\n\nResearchers 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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients aged over 18 years\n* American Society of Anesthesiologists (ASA) physical status of I-III\n* Patients scheduled for elective unilateral lobectomy via video-assisted thoracoscopic surgery (VATS) for lung cancer under general anesthesia\n* Informed consent signed\n\nExclusion Criteria:\n\n* History of liver, kidney, heart, lung, or brain disease\n* Psychiatric disorder or cognitive impairment\n* Chronic pain, daily use of analgesics, or alcohol dependence\n* Routine or recent acupuncture treatment\n* Contraindications to TENS (with pacemaker or metallic implants, allergy to surface electrodes, with skin sensory disorders, skin ulceration, unhealed scars, or adhesions)'}, 'identificationModule': {'nctId': 'NCT06744166', 'briefTitle': 'Effect of Transcutaneous Electrical Nerve Stimulation Based on Wrist-ankle Acupuncture Theory on Postoperative Pain After Video-assisted Thoracoscopic Surgery', 'organization': {'class': 'OTHER', 'fullName': 'Changhai Hospital'}, 'officialTitle': 'Effect of Transcutaneous Electrical Nerve Stimulation Based on Wrist-ankle Acupuncture Theory on Postoperative Pain After Video-assisted Thoracoscopic Surgery', 'orgStudyIdInfo': {'id': 'TENS-WAA-VATS'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'TENS-WAA group', 'description': 'Patients assigned to the TENS-WAA group will receive transcutaneous electrical nerve stimulation (TENS) based on Wrist-Ankle Acupuncture theory (WAA) for a duration of 30 minutes after anesthesia induction, as well as at 8 hours and 24 hours postoperatively.', 'interventionNames': ['Device: TENS-WAA']}, {'type': 'SHAM_COMPARATOR', 'label': 'sham TENS-WAA group', 'description': 'Patients assigned to the sham TENS-WAA group will receive sham stimulation (without stimulation)for a duration of 30 minutes after anesthesia induction, as well as at 8 hours and 24 hours postoperatively.', 'interventionNames': ['Device: Sham (No Treatment)']}], 'interventions': [{'name': 'TENS-WAA', 'type': 'DEVICE', 'description': 'Patients assigned to the TENS-WAA group will receive transcutaneous electrical nerve stimulation based on Wrist-Ankle Acupuncture theory for a duration of 30 minutes after anesthesia induction, as well as at 8 hours and 24 hours postoperatively.
