The specific practice of radiofrequency thyroid ablation is to insert a needle, or radiofrequency needle, under the guidance of ultrasound into the location where the surgery is needed, that is, the nodule in the thyroid gland. The radiofrequency needle will pass a current of 200-1200 Hz, and the heat generated by the current will destroy the local nodule tissue, causing it to be unable to work and grow normally. Patients need to get enough sleep before the procedure to ensure that they are in good condition to face the procedure. After the procedure, patients’ vital signs should be closely observed. To prevent postoperative wound bleeding, pressure can be applied to the surgical site, and pressure bandages can be applied with sand bags and ice packs, etc. Patients should start with a light diet of fluids and gradually transition to a normal diet with more nutrient-rich substances.
