Thyroid nodule surgery postoperative wound treatment for dressing change, 4-5 days or so can be removed, postoperative need to pay attention to the following aspects: 1, easy to bleed after surgery, bleeding will compress the trachea leading to respiratory difficulties. After surgery, we should pay attention to observe the patient’s wound with or without blood seepage, and also observe the patient’s respiration, if there is blood seepage and compression symptoms, we must get timely treatment, and open the drainage tube to reduce the compression symptoms if necessary; 2. It may lead to tracheal cartilage softening, because the tumor has compression symptoms for the trachea for a long time, which leads to tracheal softness, and the tissues connecting the surrounding area will have a supportive effect on the tracheal cartilage if the thyroid nodule is not resected, once it is resected, the support will disappear. When the thyroid nodule is not removed, the connecting surrounding tissues can support the tracheal tube, but once it is removed and the support disappears, the tracheal cartilage will be chondroplastic, which will cause respiratory difficulty; 3. Laryngeal edema will also cause respiratory difficulty, but it should be relieved from postoperative blood seepage or tracheal cartilage. Laryngeal edema treatment is generally used inhalation hormone therapy to reduce the laryngeal edema process; 4, postoperative voice damage and voice paralysis, because most of the postoperative thyroid nodules have the opportunity to injure the recurrent laryngeal nerve, and some even have vocal cord paralysis. There are also unexplained vocal cord paralysis, which may have nothing to do with thyroid nodule surgery, and generally the process of vocal cord paralysis does not exceed half a year, and naturally improves after half a year, so pay attention to the regular review; 5, damage to the parathyroid glands, i.e., hypothyroidism, as well as the occurrence of hypothyroidism, a part of the thyroid nodule surgery damages the thyroid gland and the occurrence of hypothyroidism, or damages to the parathyroid glands and the occurrence of hypoparathyroidism, which requires antithyroidism Antithyroid therapy and parathyroid function therapy are required. Attention should be paid to and regular follow-up of thyroid function and blood calcium are required.
