After pituitary tumor surgery, the nose usually needs to be plugged for 3-6 days before removal. The purpose of the early nasal tamponade is mainly to prevent postoperative rhinorrhea and cerebrospinal fluid nasal leakage. In addition to this, after pituitary tumor surgery, you also need to be alert to the possibility of combining urolithiasis, epilepsy and other changes. This is because after pituitary tumor surgery, it is very easy to damage the pituitary stalk, which leads to the occurrence of uremia. Once uremia occurs, it can easily lead to water and electrolyte balance disorders. Therefore, after surgery, patients need to routinely monitor the amount of urine, and need to routinely use anti-epileptic seizure drugs, but also need to regularly review endocrine hormone levels. After discharge from the hospital, head CT and MRI as well as endocrine levels need to be rechecked regularly.
