Thyroid nodule surgery can be divided into three stages: before, during and after surgery. 1. Before surgery: Before surgery, a series of physical examinations, including blood routine, blood biochemistry, blood coagulation, immunity, and thyroid imaging, need to be carried out to assess the patient’s health status and possible risks. Preoperative need to be based on whether the patient is general anesthesia to determine the need for fasting, to prepare for anesthesia, while filling out the surgical notification letter and other content. 2. During the surgery: During the surgery, the surgeon will choose the appropriate surgical procedure according to the patient’s condition, such as open surgery, where the thyroid nodule is removed on the affected side, or minimally invasive surgery using a laparoscope, which is more suitable for benign, fewer and smaller nodules. The removed tissue is sent to the pathology department for histologic examination. 3. Post-operative: The doctor will decide whether to transfer the patient to ICU or general ward according to the degree of recovery, and at the same time, he/she will keep indwelling needles and drainage tubes for the patient as appropriate, and monitor the patient’s blood pressure, heart rate and other indicators. Thyroid nodule surgery should be performed in regular hospitals.
