As a complex intracranial neoplastic disease, surgical treatment for pituitary adenoma can effectively remove the tumor; however, patients may still face a range of postoperative complications. These complications not only affect the patient's physical health but may also impact their psychological and social functioning to varying degrees. Therefore, understanding the possible postoperative complications, their severity, likelihood of occurrence, and correspoding nursing measures is crucial for patient recovery.

I. Common Postoperative Complications and Their Severity

1. Hemorrhage and Hematoma

Hemorrhage and hematoma are common complications after pituitary adenoma surgery. Bleeding may arise from the surgical wound, nasal cavity, or sinuses, and in severe cases can lead to elevated intracranial pressure and even become life‑threatening. A hematoma may compress surrounding tissues, causing pain, swelling, and other symptoms. The severity of hemorrhage and hematoma varies with the amount of bleeding and its location, and they require prompt detection and management.

2. Infection

Since pituitary surgery involves intracranial manipulation, the risk of infection is relatively high. Infection may occur at the surgical site, nasal cavity, or sinuses, manifesting as redness, swelling, pain, and increased discharge. Severe infection can lead to intracranial infection, meningitis, and other life‑threatening complications. Therefore, close postoperative monitoring of infection indicators and clinical signs is essential for early detection and treatment.

3. Hypopituitarism

Surgery for pituitary adenoma may damage pituitary tissue, resulting in hypopituitarism. The manifestations of hypopituitarism are diverse, including deficiencies in endocrine, thyroid, and adrenal functions. Severe hypopituitarism may cause life‑threatening symptoms such as coma and shock. Thus, postoperative pituitary function should be closely monitored to detect and manage hypopituitarism promptly.

4. Water‑Electrolyte Imbalance

Patients are prone to water‑electrolyte disturbances after pituitary surgery, mainly presenting as hyponatremia, hypokalemia, etc. Such imbalances may cause headache, nausea, vomiting, and fatigue, and in severe cases may affect neurological function and vital signs. Accordingly, serum electrolyte levels should be regularly monitored and treatment adjusted as needed.

5. Visual Impairment

Some patients already have visual problems before surgery, and vision may deteriorate further postoperatively. This decline may be related to surgical injury to the optic nerve or to optic atrophy caused by tumor compression. The degree of visual loss varies among patients, and some may experience irreversible visual damage. Hence, postoperative visual changes must be closely observed and addressed without delay.

6. Other Complications

Besides the above, other complications such as cerebral edema, brain herniation, and cardiovascular events may also occur after pituitary adenoma surgery. The severity of these complications varies, so careful monitoring of the patient's condition is necessary to enable early recognition and intervention.

II. Likelihood of Postoperative Complications

The probability of complications after pituitary adenoma surgery varies depending on the patient's individual circumstances. Generally, younger patients, those with smaller tumors, and those undergoing standardized surgical procedures have a lower complication rate, whereas elderly patients, those with larger tumors, and those with complex surgical manipulations have a higher rate. In addition, the patient's general health and comorbidities also influence the occurrence and progression of complications. Therefore, before surgery, physicians should fully assess the patient's condition and risks to design an appropriate surgical plan; after surgery, close monitoring is required for timely detection and management of complications.

III. Postoperative Nursing Care Measures

Nursing care after pituitary adenoma surgery is vital for recovery. The main measures include:

1. Close Observation of the Patient's Condition

Postoperatively, patients need to be closely observed in the intensive care unit or neurosurgical ward, with monitoring of vital signs, mental status, pupillary responses, limb movements, etc. Nurses should record changes regularly and promptly identify and address any abnormalities.

2. Maintaining a Clear Airway

Patients may have increased respiratory secretions after surgery; these secretions should be cleared in a timely manner to ensure airway patency. For those requiring oxygen therapy, adequate oxygen delivery must be guaranteed to avoid hypoxia.

3. Preventing Infection

Strict aseptic technique should be followed to prevent infection. Nurses should regularly change the patient's bed linens and keep the skin clean and dry. For patients with surgical wounds, dressings should be changed periodically and wound healing observed.

4. Monitoring Water‑Electrolyte and Acid‑Base Balance

Postoperative monitoring of water‑electrolyte and acid‑base balance should be performed regularly, and treatment adjusted accordingly. Nurses should administer fluid, sodium, and potassium supplementation as prescribed to maintain electrolyte equilibrium.

5. Promoting Recovery of Pituitary Function

For patients with hypopituitarism, measures should be taken to facilitate pituitary function recovery. Nurses should assist the physician in providing hormone replacement therapy and encourage the patient to engage in rehabilitation exercises to enhance overall resistance.

6. Diet and Nutritional Support

Postoperatively, patients should develop a reasonable dietary plan based on their specific condition to meet nutritional needs. For those with difficulty eating, nutrition can be supplemented via nasogastric tube or gastrostomy. Nurses should closely monitor nutritional status and adjust the diet plan as necessary.

7. Psychological Care

Pituitary surgery may have a considerable psychological impact on patients, requiring psychological support. Nurses should establish a good nurse‑patient relationship, understand the patient's psychological needs, and provide encouragement and reassurance. Additionally, a psychologist may be invited to offer intervention and counseling to help the patient build confidence in overcoming the illness.

Postoperative Complications of Pituitary Adenoma Surgery and How to Implement Nursing Care Measures?

In summary, the risk of complications after pituitary adenoma surgery is relatively high, necessitating close observation of the patient's condition and timely detection and treatment of any complications. At the same time, patients and their families should cooperate with the medical team's treatment and nursing efforts, working together toward the patient's recovery.

Note: INC International Neurosurgeon Circle's International Neurosurgical Advisory Group (WANG) includes many internationally renowned professors with superb surgical skills and extensive successful case experience, such as Professor Sébastien Froelich (France), former Chairman of the Skull Base Surgery Committee of the World Federation of Neurosurgical Societies (WFNS). He specializes in endoscopic endonasal resection of skull base tumors, performing minimally invasive surgeries via neuroendoscopy for complex brain tumors including chordomas, craniopharyngiomas, and pituitary adenomas. His "chopsticks" technique in endoscopic surgery not only improves the tumor resection rate but also leads to better prognoses for tumor patients.

As a bridge connecting neurosurgical experts between China and other countries, INC International Neurosurgeon Circle has, in recent years, organized visits by international professors to China for academic exchanges, technological discussions, and high‑difficulty surgeries; it has also cooperated with multiple domestic hospitals to promote the common development of neurosurgery both domestically and internationally, providing more new treatment options for neurosurgical patients worldwide.
