Syndrome of inappropriate secretion of antidiuretic hormone in malignancy
1Rush-Presbyterian-St Luke's Medical Center, Chicago, IL, USA.
Objectives:
To provide a review of pathophysiology, epidemiology, signs and symptoms, diagnosis, treatment, and nursing management of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) in malignancy.
Data Sources:
Research reports, review articles, and book chapters relevant to SIADH.
Conclusions:
The principle cause of hyponatremia in malignancy is SIADH. Early recognition and prompt treatment can prevent serious neurologic sequelae. Antineoplastic therapy and methods to correct hyponatremia constitute effective treatment strategies.
Implications For Nursing Practice:
Nurses play a major role in nursing assessment, appropriate interventions and symptom control, and promoting resolution of problems and optimal quality of life in patients with malignancy complicated by SIADH.
