Parathyroid adenoma surgery is divided into preoperative preparation, surgery, postoperative observation, if everything is normal, it can be discharged from hospital in about 7~10 days. Preoperative preparation: about 1~3 days before the operation, routine blood tests, blood electrolytes, chest CT, electrocardiogram, neck CT, etc. should be performed to determine whether the patient can tolerate the operation, whether there are contraindications and the location of the adenoma. This can be followed by preoperative anesthesia evaluation. Surgery should be performed carefully as required. Postoperative observation: After the operation, it is usually necessary to stay in the hospital for 5-7 days for observation, mainly observing the patient’s vital signs, whether there is any local bleeding from the incision, whether there is any infection of the surgical wound, etc., and checking the blood calcium situation. Generally no special circumstances can be discharged. In short, under normal circumstances 7~10 days can be discharged, but the specific time should be strictly in accordance with the doctor’s arrangements.
