- Discussion:
- determine volume status of the patient;
- rx of
SIADH (Normovolemic)
- rx of
Volume Depleted hyponatremia;
- rx of
Volume Excess hyponatremia
- if the patient has Normal ECF volume,
SIADH,
psuedohyponatremia, or endocrine d/o (hypothyroidism) should be considered;
- many hyponatremic states are asymptomatic until the serum sodium level falls well below 120 mEq per liter;
- one important exception is the patient with increased CSF pressure, such as following closed head injury, in which mild hyponatremia may
be extremely deleterious, even fatal;
- this is due to the progressive increase in intracellular water (further increaseing intracranial pressure) as the extracellular
fluid osmolarity falls);
