To investigate the therapeutic effect of Qingre Jieyu Decoction (清热解瘀汤) on the patients with thyroid nodules after ablation.

A hundred patients with thyroid nodules undergoing radiofrequency ablation treated in Guangdong Province Traditional Chinese Medical Hospital from June 2021 to June 2023 were included as the study objects, and were divided into two groups by the random number table method. Fifty patients in the control group were treated with conventional western medicine after radiofrequency ablation, and those in the observation group were treated with Qingre Jieyu Decoction after radiofrequency ablation. The therapeutic effects, symptom scores, maximum diameters and volumes of thyroid nodule, thyroid function indexes and so on of the two groups were compared.

After treatment, the total effective rate of the observation group was 96.0%, which was much higher than that of the control group (78.0%), and the scores of pain, swallowing discomfort, swelling and thermal swelling in the observation group were lower than those in the control group (P<0.05). After treatment, the nodule maximum diameter and nodule volume in the observation group were smaller than those in the control group, and the levels of serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) after treatment were better than those in the control group (P<0.05).

The application of Qingre Jieyu Decoction after radiofrequency ablation for the patients with thyroid nodules can relieve heat and toxin, eliminate abscess and desiccation, effectively improve swallowing discomfort, swelling, pain and other symptoms of the patients after surgery, promote the reduction of thyroid nodules, improve the thyroid function and promote postoperative recovery as soon as possible.
