Hyperthyroidism, referred to as hyperthyroidism, is an autoimmune disease. Its clinical manifestations are not limited to the thyroid gland, but rather a multi-system syndrome, which mostly manifests as fever, excessive sweating, agitation, hyperactivity with weight loss, tachycardia at rest, specific eye signs, and goiter. There are three main treatment methods, namely, medical drug therapy, iodine 131 radiation therapy and surgical treatment. Surgical indications for hyperthyroidism Moderate or severe hyperthyroidism with unsatisfactory long-term drug treatment and repeated relapses, or with difficulties in long-term drug treatment or persistence; nodular goiter with hyperthyroidism or high-functioning adenoma; obvious enlargement of the thyroid gland (grade III or higher) with compression of surrounding organs or post-thoracic goiter; hyperthyroidism combined with thyroid cancer; children with poor results of anti-thyroid drug treatment; pregnancy Those with poorly controlled mid-stage hyperthyroidism medication; Pre-operative preparation Precautions Patients must be treated with anti-thyroid medication (Sage or Tabazol) to restore thyroid function (mainly TT4, FT4, TT3 and FT3) to normal, without the need to pursue the control of TSH to normal levels. The basal metabolic rate is controlled between 0-20% and the heart rate is generally controlled at about 80 beats/min. After this condition is reached, you can start taking Lugol’s solution (iodine) after agreeing with your surgeon on the date of surgery. The dose should be taken three times a day, starting with 3 drops/session and increasing by one drop each time daily, gradually increasing to 16 drops/session and maintaining it. Taking Lugol’s solution directly tastes extremely bad, so you can put Lugol’s solution drops on bread buns or crackers to make it easier to take. Be sure to take care not to exceed 1 week after maintaining the 16-drop dose. Generally antithyroid medications can be taken until 5-7 days before surgery when they are discontinued. Patients with an accelerated heart rate may be given a heart rate control medication. Attachment: Basal metabolic rate = (pulse rate + pulse pressure) – 111
