## How do you calculate sodium deficiency?

Na+ Deficit (mEq) = (Desired Na+ – Measured Na+) x 0.6 L/kg x Weight (kg)

Change in serum Na+ = (infusate Na+ + infusate K+) – serum Na+
total body water + 1

### How is sodium corrected in hyponatremia?

In patients with severe symptomatic hyponatremia, the rate of sodium correction should be 6 to 12 mEq per L in the first 24 hours and 18 mEq per L or less in 48 hours. A bolus of 100 to 150 mL of hypertonic 3% saline can be given to correct severe hyponatremia.

How do you calculate sodium?

Sodium (mg) × 2.54 ÷ 1,000 = Salt content (g). Sodium content is sometimes expressed in grams. In these cases, use the formula “Sodium (g) × 2.54 = Salt content (g).” For example, an item with 1,000 mg of sodium would have a sodium chloride equivalent of 2.54 g.

#### How many Na is 3% ns?

Table 1

size (mL) Composition (g/L)
Sodium Chloride USP (NaCl)
3% Sodium Chloride Injection, USP 500 30
5% Sodium Chloride Injection, USP 500 50
*Normal physiological osmolarity range is approximately 280 to 310 mOsmol/L. Administration of substantially hypertonic solutions ( ≥ 600 mOsmol/L) may cause vein damage.

Will 0.9 ns increase sodium levels?

Additionally, the infusion of more than one liter of isotonic (0.9%) sodium chloride per day may supply more sodium and chloride than physiological levels, which can lead to hypernatremia, as well as hyperchloremic metabolic acidosis.

## How to manage 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.

When to treat hypernatremia?

In severe hypernatremia or in patients unable to drink because of continued vomiting or mental status changes, IV hydration is preferred. Hypernatremia that has occurred within the last 24 hours should be corrected over the next 24 hours.

### Which medications are used in the treatment of hypernatremia?

Hydrochlorothiazide (Esidrix,HydroDiuril,Microzide) Inhibits the reabsorption…

• Furosemide (Lasix) Loop diuretic that increases excretion of water by interfering with chloride-binding…
• Desmopressin (DDAVP) Increases cellular permeability of collecting ducts,…
• How much fluid restriction for hyponatremia?

Mild hyponatremia can be treated by restricting fluid intake to less than 1 quart (about 1 liter) per day. If a diuretic or other drug is the cause, the dose is reduced or the drug is stopped. If the cause is a disorder, it is treated.
