Pediatric Syndrome of Inappropriate Antidiuretic Hormone Secretion Follow-up
- Author: Robert J Ferry Jr, MD; Chief Editor: Stephen Kemp, MD, PhD more...
Further Inpatient Care
Closely monitor serum and urine electrolytes in patients with syndrome of inappropriate antidiuretic hormone (SIADH) secretion. Reassess the patient's status frequently and readjust therapy as necessary.
Further Outpatient Care
Restrict fluid to 1000 mL/m2/d.
Inpatient & Outpatient Medications
The use of lithium carbonate should be considered in children with chronic syndrome of inappropriate antidiuretic hormone secretion. Demeclocycline can be used in children older than 8 years with chronic syndrome of inappropriate antidiuretic hormone secretion.
Complications
The following complications are noted:
- Fluid overload
- Pulmonary edema
- Hypertension
- Anasarca
- Acute extracellular hypoosmolality
- Cerebral edema (may be observed at rates of plasma osmolality decrease faster than 10 mOsm/kg/h)
- Permanent brain damage
- Cerebral herniation (has been observed in postmortem examination in both humans and experimental animals)
Prognosis
Prompt recovery usually follows water restriction. Prognosis of syndrome of inappropriate antidiuretic hormone secretion is usually that of the underlying disease.
Patient Education
Stress the importance of fluid restriction in maintaining reference range serum sodium levels.
