SIADH is a syndrome that stands for Syndrome of inappropriate antidiuretic hormone secretion. When a person has this syndrome, then their body secretes too much of the hormone known as antidiuretic hormone. This comes from the pituitary gland or another gland. There are six known causes to this problem and they are cancer, drugs, lung diseases, hereditary, central nervous system diseases, and transient conditions.
If a patient has a head injury due to a fall, they may be diagnosed as syndrome of inappropriate antidiuretic hormone. The patient may detail to the nurse the symptoms of losing weight, urinating more often and a decrease in urine osmolarity. When the nurse sees these signs, there is a good chance that the patient should be treated for SIADH.
Decrease in body weight-2. increase in urine output-3. decrease in urine osmolarity-rationale: siadh is an abnormality involving an abundance of diuretic hormone. the predominant feature is water retention with oliguria, edema, and weight gain. successful treatment should result in weight reduction, increased urine output, and a decrease in the urine concentration (urine osmolarity). as edema decreases, the blood pressure should decrease, not increase. also, as the client loses fluid, his lungs should be clear of crackles, not wheezes.client needs category: physiological integrityclient needs subcategory: physiological adaptationcognitive level: analysisreference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 318.
