Hyperthyroidism, or hyperthyroidism for short, is an endocrine disease characterized by systemic hypermetabolism due to excessive secretion of thyroxine from various causes, which can have a great impact on the body and mind. The clinical manifestation of hyperthyroidism is an enlarged thyroid gland. Patients often show signs of hyperactivity, such as hyperphonia, impatience, agitation, insomnia, rapid trembling of the hands, fear of heat, excessive sweating, and warm skin. In typical cases, there is also a protrusion of the eyeballs bilaterally and a widening of the eye fissure. Pre-operative instructions: Please cooperate with the medical staff to complete relevant examinations before surgery. The nurse will measure your basal metabolic rate early in the morning while you are awake, fasting, lying down, and relaxed, so that you can choose the right time for surgery. The nurse will also prepare your medication, i.e. iodine and other medications. Please strictly follow the iodine schedule prepared by the nurse for you and do not take more, less or no medication to facilitate the smooth operation and prevent postoperative complications. Your diet should be high in calories, high in protein, and rich in vitamins, with sufficient fluid intake to replenish water lost through sweating, etc. Eat small and frequent meals and enhance nutrition. Avoid strong tea, coffee and other stimulating drinks, and quit smoking and alcohol. If you have difficulty sleeping at night, inform the medical staff in time and take Valium as prescribed by the doctor. Postoperative instructions: Family members should cooperate with the nurse to observe the changes of the patient’s breathing. After awakening from general anesthesia and stabilization of vital signs, take a semi-recumbent position, continue low-flow oxygen inhalation, cough effectively, insist on nebulized inhalation, eliminate sputum effectively in time, and keep the respiratory tract unobstructed. If respiratory difficulty occurs, report to the doctor in time. If there is no choking and coughing, mis-swallowing and other discomfort, the patient can have a warm and cool liquid diet, and then gradually transition to semi-liquid and soft food. After surgery, continue to take iodine 3 times a day, starting with 16 drops each time and decreasing by 1 drop each time day by day until 3 drops are stopped. Routinely place a neck drain after surgery and pay attention to maintaining effective drainage. Use your hand to fix the neck when changing position in bed, getting up and coughing to reduce pain. Instructions for discharge: Learn to control your emotions, keep your mind happy and calm. After the stitches are removed, practice neck movement to restore function as soon as possible, and visit the outpatient clinic regularly for review and timely consultation for discomfort.
