How do you fix hypovolemic hyponatremia?

The most common treatment option proposed for patients with hypovolemic hyponatremia is replacement of both salt and water through the intravenous infusion of sodium chloride solutions.

Which is the best fluid to treat a patient with mild hyponatremia?

In general, hyponatremia is treated with fluid restriction (in the setting of euvolemia), isotonic saline (in hypovolemia), and diuresis (in hypervolemia). A combination of these therapies may be needed based on the presentation. Hypertonic saline is used to treat severe symptomatic hyponatremia.

How is hypervolemic hyponatremia diagnosed?

Hypervolemic hyponatremia Laboratory tests include a complete metabolic panel and urinary sodium and creatinine levels. Serum osmolality and fractional excretion of sodium should be calculated (eTable A).

What is rapid correction of hyponatremia?

Overly rapid correction of hyponatremia is defined as a plasma sodium correction rate exceeding the recommended limits, but controversy still exists about what those limits are. Two common limits used are (1) >10–12 mEq/L in the first 24 hours and >18 mEq/L in the first 48 hours; and (2) >8 mEq/L in any 24-hour period.

What IV solution is used for hyponatremia?

For serious symptomatic hyponatremia, the first line of treatment is prompt intravenous infusion of hypertonic saline, with a target increase of 6 mmol/L over 24 hours (not exceeding 12 mmol/L) and an additional 8 mmol/L during every 24 hours thereafter until the patient’s serum sodium concentration reaches 130 mmol/L.

What causes hypervolemic hyponatremia?

The three main causes of hypervolemic hyponatremia are congestive heart failure, liver cirrhosis, and renal diseases such as renal failure and nephrotic syndrome. These disorders usually are obvious from the clinical history and physical examination alone.

Can hyponatremia be cured?

Hyponatremia treatment is aimed at resolving the underlying condition. Depending on the cause of hyponatremia, you may simply need to cut back on how much you drink. In other cases of hyponatremia, you may need intravenous electrolyte solutions and medications.
