The care during thyroid ablation is carried out before, during and after the ablation, as follows: 1. Before the ablation, pay attention to the patient’s basic conditions, such as heart rate, blood pressure, oxygen saturation and other vital signs, as well as coagulation function and blood glucose; 2. During the ablation, the patient’s vital signs need to be monitored to see the changes in blood pressure, heart rate and oxygen saturation. If the patient has elevated blood pressure, take appropriate treatment measures. Intraoperative nursing staff communicate with patients warmly and create a warm atmosphere, which can also relieve the patient’s psychological tension, while cooperating with the doctor for evaluation; 3. After ablation, swelling and edema of the neck may be caused, so attention should be paid to the change of vital signs after surgery, and the patient is also required to apply local compression for half an hour, and then apply local ice packs for two hours after compression, which is beneficial to the absorption of local edema.
