Clinically, there is a difference in what you need to pay attention to after surgery depending on the location of the nodule. After surgery for breast nodules, attention needs to be paid to the healing of the incision. Patients need to be in the breast incision, local elastic bandage pressure. Avoid the accumulation of fluid and blood under the incision, resulting in delayed healing of the incision. For patients with fluid accumulation under the incision, it is necessary to open the incision as soon as possible, remove the subcutaneous fluid, and strengthen the incision dressing. After surgery for thyroid nodules, the following should be noted: 1. Observe whether the patient has a subcutaneous hematoma compressing the trachea, and the patient has symptoms such as dyspnea; 2. Observe whether the patient has a hoarse voice due to the damage of the recurrent laryngeal nerve; 3. Observe whether the patient has a hypocalcemic convulsion due to the damage of the parathyroid gland’s blood supply.
