After total thyroidectomy, it is usually necessary to leave a drainage tube under the skin in the neck. The first step is to take good care of the drainage tube by intermittent squeezing to avoid blockage of the tube. It is also important to monitor changes in blood pressure and heart rate. Some patients are prone to thyroid hormone deprivation and hypothyroidism after surgery and can be treated with hormones as well as thyroxine tablets if necessary. During the postoperative recovery period, it is important to pay attention to a full liquid diet and soft diet, as chewing and swallowing can lead to the appearance of pain, and to choose a high, semi-recumbent position to facilitate drainage. It is also important to monitor the blood routine and blood ions regularly, because the postoperative period may lead to ischemia of the parathyroid glands, which may induce twitching and numbness of the hands and feet. Therefore, routine calcium supplementation is also needed, and calcium gluconate intravenous drip can be applied.
