Due to the short hospital stay after thyroid surgery, often 2-3 days after surgery, you may have some problems during the period that you cannot communicate with your doctor, I believe the following can solve some of your confusion. 1. Wound care: Generally, you are discharged on the day of extubation or the next day. The drainage duct opening may not have healed and there will be a small amount of exudate, which is normal, and if the dressing is wet, you will need to change the dressing again. This is normal, and if the dressing is wet, it will need to be changed again. It usually heals in 1-2 days. Sometimes there will be fluid under the incision, bulging, this is not to worry, let the doctor fine needle puncture drainage, usually 1 time can solve the problem. The wound is initially like a thin red line, the surrounding tissue will be somewhat edematous, and there will be a pulling sensation in the neck when swallowing, which are all normal steps in the wound healing process. Generally, after 1 week, if the incision does not ooze, it can be flushed with water. The neck pulling sensation will be relieved when the tissue scar is softened, which will take 3-6 months, or more than 1 year for those with special constitution. 2. Medication taking: Usually the doctor will care to take medication, such as Eugenol, when you are discharged from the hospital. This drug should be taken in the morning on an empty stomach in the state of the full dose of the day, and eat breakfast about half an hour after taking the drug, so that the side effects of the drug can be minimized and the efficacy is best. Beginners sometimes forget, then take the medicine at the first sign of remembering. The main side effects of the drug are headache, heartburn and high blood pressure. However, long-term use of thyroxine preparations will not cause adverse effects on the body as long as thyroid function is checked regularly and the dosage is appropriate. In addition, if there are patients with tingling in the hands and feet, they should be treated seriously with calcium supplementation. 3. Review time: generally 2 weeks after discharge from the hospital, let the doctor know about the incision healing and medication. The thyroid function should be checked once every 6 weeks at the beginning of the medication, and if it is stable, the time will be extended later. The ultrasound should be repeated 3 months after surgery. 4. Dietary problems: This issue is widely divergent. Generally, Western doctors do not have many contraindications, such as eggs, chicken, pigeons, fish, soy sauce, etc. There is also the concern about iodized salt and foods containing high iodine, such as kelp, seaweed, nori, etc. There are reports in the literature that high iodine can cause nodule growth. Since we are located in an iodine-rich region and are not deficient in iodine, we should not consume too much of these foods. In addition, a small number of scholars have found that excessive smoking and alcohol consumption may contribute to the development of nodules.
