Study Notes
- Syndrome of inappropriate antidiuretic hormone secretion (SIADH) and diabetes insipidus (DI) are two disorders related to the activity of antidiuretic hormone (ADH) released by the pituitary gland.
- In SIADH, there is an inappropriate secretion of ADH leading to the retention of excess water in the body, hyponatremia, hypo-osmolality, and significant complications like water intoxication, cerebral edema, and heart failure.
- On the other hand, DI involves either insufficient ADH production in central DI or kidney resistance to ADH in nephrogenic DI, resulting in polyuria with urine output exceeding 3L/24 hours in adults and 2L/24 hours in children. Severe cases can lead to 10-20 L/day urine output.
- Causes of SIADH include CNS disorders, cancer, cardiopulmonary diseases, while DI can be caused by hypothalamic or pituitary damage, kidney diseases, certain drugs, genetic defects, leading to complications like hypovolemia, circulatory collapse, and CNS changes.
- Monitoring for both SIADH and DI involves vital signs, intake and output, weight, urine and serum electrolyte levels (especially sodium), neurologic status, cardiac function, and response to treatment. Additional monitoring for DI includes blood urea nitrogen levels, urine specific gravity, osmolality, and signs of hypovolemic shock.
