Radiofrequency ablation of pulmonary nodules does not always require shaving. Shaving before the procedure is called skin preparation, and skin preparation of the surgical site keeps the skin in the surgical area clean and adequately sterilized to avoid infection. The main ways to treat lung nodules by radiofrequency ablation are percutaneous radiofrequency ablation and transbronchial duct radiofrequency ablation. And percutaneous radiofrequency ablation to shave. Percutaneous radiofrequency ablation is guided by CT or ultrasound, the puncture needle is punctured to the lung nodule, and then connected to the radiofrequency ablation machine for 20 to 30 minutes, so that the temperature of the lung nodule is increased to 50-60 degrees, so as to make the lung nodule degenerate and necrosis. Bronchoscopic radiofrequency ablation involves directing a bronchoscope through the body’s natural cavity to the lesion. With no general anesthesia, good prognosis and quick recovery, radiofrequency ablation is an effective treatment for lung nodules. It is recommended that patients who need radiofrequency ablation go to a regular hospital and follow the doctor’s advice for treatment.
