The following is instructive, informative and beneficial for patients who are about to undergo or have undergone thermal ablation of thyroid nodules. First Consultation 1. Metal implants in the body, such as steel plates, steel nails, metal stents, metal clips, pacemakers, cardiac stents, etc., need to be informed to the examining physician in time, so as to facilitate the development of an appropriate ablation program. 2.Long-term use of drugs to activate blood circulation and remove blood stasis, such as aspirin, compound danshen, panax ginseng, poliovirus, heparin, etc., need to inform the examining physician immediately, and need to stop taking drugs for more than 10 days before performing puncture biopsy or ablation treatment. Before the procedure 1. One day before the procedure, take a bath, shampoo, change clothes and socks, and wear soft, loose-fitting, lapel tops. Women should avoid wearing dresses, tight clothes, jewelry and bras. Hospitalized patients should change into standard surgical gowns. 2, two days before and on the day of surgery, avoid drinking alcohol, avoid eating garlic, green onions, onions and other stimulating odor food. 3. Three hours before the operation, please refrain from eating and drinking. For those with abnormal blood sugar and blood pressure, please eat and take medication as usual three hours before the operation. Please defecate and urinate in advance. 4.Disinfected towel sheets cover the head and face during surgery, which will make some patients feel uncomfortable and nervous, please do head covering training in advance to relax and adapt to the surgical environment. 5.If you have symptoms such as cough, runny nose, phlegm, etc., please treat them in advance and inform the surgeon. During the operation 1. Relax your body, lie face up, unbutton your clothes fully and expose your neck and chest fully according to the requirements of the operation. 2. There will be mild tingling when injecting anesthesia; toothache, headache, earache, or neck pain may occur during radiofrequency and microwave ablation treatment, but usually these pains can be tolerated. 3.Injection of isolation fluid may have swelling pain, but will not affect the whistle. 4. During surgery, you should try to distract yourself and relax to help reduce swallowing. Swallowing is a reflex activity that is difficult to control, so try to avoid rapid and large swallows. 5.If there is intolerable pain or uncontrollable coughing or swallowing during the operation, please gently wiggle your fingers to signal the doctor to pause the operation. Postoperative 1, 2-3 hours after the operation, should not drink, eat, please lie down and rest, keep the neck ice bag compression. 2.Neck pain can last for 3-6 hours and can be tolerated. 3.Keep the skin puncture place dry, the dressing can be removed after 12-24 hours. 4.Diet as usual, but within three months must avoid spicy food, alcohol and tobacco, avoid staying up too late and overwork. 5, according to the doctor’s instructions for regular follow-up, follow-up. If there is any abnormal discomfort, especially when there is redness, swelling and pain in the neck, immediate follow-up is needed. 6.When you find that there are abnormalities in 5~7 indicators of thyroid function (blood test), do not take medication on your own first, consult the attending doctor in time and get a reasonable explanation. After ablation of thyroid cancer, it is necessary to take eugenol, which aims to reduce the thyroid stimulating hormone in the blood to between 0.1 and 0.01, and it is inevitably accompanied by the rise of thyroid hormones (T3 and T4), so there is no need to be alarmed. 7.Patients diagnosed with papillary carcinoma need to have another puncture biopsy to assess the efficacy of the pathologic grade 3 months or 6 months after ablation.
