Effect of Transcutaneous Acupoint Electrical Stimulation (TAES) on Postoperative Cough in Lung Cancer

This study is testing whether transcutaneous acupoint electrical stimulation (TAES) — a non-invasive technique similar to acupuncture but using gentle electrical pulses on the skin at specific points — can reduce persistent dry cough that often develops after lung cancer surgery. Post-surgical cough can be uncomfortable and affect recovery, and researchers want to know if TAES offers relief. **You may be eligible if...** - You are between 18 and 80 years old - You had surgery to remove lung cancer (under general anesthesia) and the cancer was confirmed by pathology - You have had a persistent dry cough for at least 2 weeks after the surgery - You are mentally alert, can communicate clearly, and are willing to consent **You may NOT be eligible if...** - You were diagnosed with an acute respiratory infection within the past month - Your chest X-ray shows pneumonia - You have a history of asthma or tuberculosis - You have uncontrolled thyroid problems, severe high blood pressure, serious heart disease, active systemic infection, or blood clotting disorders - You have a pacemaker or have had electroacupuncture in the past 3 months Talk to your doctor to see if this trial is right for you.
