### Target Population

Designed for patients who have undergone transsphenoidal surgery (TSS). This type of surgery is typically performed to remove pituitary tumors. The protocol identifies patients based on specific surgical codes (ICD-10-PCS, SNOMED CT, and CPT).

### Recommendations

The protocol recommends instructing patients to restrict their fluid intake to 1 liter per day for 7 days following their surgery. This recommendation is based on clinical evidence showing that such fluid restriction helps prevent the development of Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH), a common complication after TSS.

### Importance

Preventing SIADH is crucial in post-operative care for TSS patients. SIADH can lead to significant complications, including hyponatremia, which can cause confusion, seizures, and other severe neurological issues. By implementing this fluid restriction protocol, clinicians can reduce the risk of SIADH, improving patient outcomes and reducing the likelihood of extended hospital stays or readmissions.

### Conclusion

This protocol integrates into the clinical workflow by automatically identifying eligible patients who have recently undergone transsphenoidal surgery and providing clinicians with a prompt to recommend fluid restriction. By doing so, it helps standardize post-operative care, ensuring that all patients receive the necessary guidance to prevent SIADH, thereby improving overall patient safety and clinical outcomes.

### The management and outcome of hyponatraemia following transsphenoidal surgery: a retrospective observational study

Hyponatraemia is a common complication following transsphenoidal surgery. However, there is sparse data on its optimal management and impact on clinical outcomes. The aim of this study was to evaluate the management and outcome of hyponatraemia following transsphenoidal surgery.
