Medication is usually changed 3 days after thoracoscopic surgery, but should be changed promptly if heavier oozing or bleeding occurs. Thoracoscopic surgery is a minimally invasive surgery, which is less invasive, with smaller incisions and less pain, relatively little impact on cardiopulmonary function, fewer postoperative complications and faster recovery. It is usually sufficient to change the medication 3 days after the operation. However, a small number of patients may have oozing and bleeding from the incision, soaking the gauze, and need to change the medicine in time to avoid infection. After surgery, you should pay attention to rest, avoid excessive tension and exertion, eat a light diet, avoid spicy and stimulating foods to facilitate recovery. If there is any discomfort, it is recommended to go to a regular hospital and be treated under the guidance of professionals.
