Diabetes Insipidus (DI) Post-operative Neurosurgical Management

Pathway Background and Objective(s)

Diabetes Insipidus (DI) refers to the passage of large volumes of dilute urine, and may result from the decreased secretion of antidiuretic hormone (ADH) by the posterior pituitary gland. Patients undergoing neurosurgical surgery in the sellar or parasellar region are at increased risk for post-operative DI, which may be transient, triphasic (DI à SIADH à DI), or permanent. Patients who do not have an intact thirst mechanism (adipisic central DI) are a particular challenge, as they may not drink enough to replace their urine losses, which can result in severe hypernatremia. Uncontrolled hypernatremia has adverse effects, including increased risk of neurological sequelae and venothromboembolism. In addition, provider variability and inconsistent care delivery can be significant barriers in establishing a timely diagnosis of DI. The objectives of this pathway are to:

  • Standardize the management of post-operative patients at risk for developing DI by standardizing:
    • Initial PICU monitoring for the development of DI
    • Initial PICU management if DI develops
    • Medical readiness criteria for patients to transfer to the med/surg floors
  • Standardize the management of post-operative patients with confirmed DI in the PICU and on the floors by:
    • Minimizing fluctuations in sodium levels and volume status
    • Expediting the development of an outpatient plan in order to facilitate a safe discharge home
