| Normal saline | 0.9% | 154 |
| D5 0.50% normal (D5 half-normal) | 0.45% | 75 |
| D5 0.33% normal (D5 third-normal) | 0.33% | 50 |
| D5 0.2% normal (D5 fifth-normal) | 0.18% | 30 |
Useful hint: if you ever have to convert grams of salt (NaCl) into mEq of Na, just remember normal saline: 9G of salt = 154 mEq of Na. You can apply this conversion factor to any other amount.
Normal Saline (0.9% NaCl) has 154 mEq/L of NaCl. Therefore, D5 0.2 NS with 20 mEq of KCl per liter is an appropriate maintenance fluid for all people.
It contains 154 mEq/L sodium and 154 mEq/L chloride.
PF 5% DEXTROSE, 0.2% SODIUM CHLORIDE is a solution that contains sodium and chloride ions and glucose, which are fundamental for the body and it is administered intravenously. PF 5% DEXTROSE, 0.2% SODIUM CHLORIDE is available in glass bottles with volumes of 500 and 1000 ml with or without sets.
NaCl 11.7 g Distilled water to make 1 liter Dispense in suitable containers. Autoclave 15 min at 121°C.
The serum sodium concentration is determined by the amount of sodium and potassium dissolved in body fluids, and by the volume of body water: Serum [ Na ] = Total body soluble ( Na + K) Total body water .
- Fluid rate (mL / hour) = [(1000) * (rate of sodium correction in mmol / L / hr)] / (change in serum sodium)
- Change in serum sodium = (preferred fluid selected sodium concentration - serum sodium concentration) / (total body water + 1)
A couple of paragraphs above, this author's simplified calculations suggest that the serum sodium will rise by 0.6 mmol/L.
Note: The milliequivalent (mEq) is the unit of measure often used for electrolytes. It indicates the chemical activity, or combining power, of an element relative to the activity of 1 mg of hydrogen. Thus, 1 mEq is represented by 1 mg of hydrogen (1 mole) or 23 mg of Na+, 39 mg of K+, etc.
How do you calculate mEq of sodium in fluids?
mEq = mg x Valence / Atomic, formular, or m.
Thus, a minimum average requirement for adults can be estimated under conditions of maximal adaptation and without active sweating as no more than 5 mEq/day, which corresponds to 115 mg of sodium or approximately 300 mg of sodium chloride per day.
| Concentration | mmol/L Na | Osmolarity (mosm/L) |
|---|---|---|
| 0.9% NaCl ("Isotonic", "Normal Saline") | 154 | 310 |
| 3% Hypertonic NaCl | 513 | 1,025 |
Mix eight teaspoons of salt into 1 gallon (4 L) of distilled water. Refrigerate solution and use within one month.

Both 0.2 NaCl and 0.45 NaCl are hypotonic fluids, 0.9 NaCl is considered isotonic.
Add 8 teaspoons of salt to 1 gallon of distilled water that you can buy in a pharmacy.
"Normal saline" is an aqueous solution of 0.9% NaCl. This means that normal saline can be prepared by measuring out 0.9 g of NaCl and diluting this amount of NaCl to a final volume of 100 ml's in water. This would be the same as diluting 9 g of NaCl to a final volume of 1 liter in water.
How do you calculate sodium chloride saline solution?
The sodium chloride equivalent is correctly calculated using the following formula: Sodium (mg) × 2.54 ÷ 1,000 = Salt content (g). Sodium content is sometimes expressed in grams.
Eating too much sodium may raise blood pressure and cause fluid retention, which could lead to swelling of the legs and feet or other health issues. When limiting sodium in your diet, a common target is to eat less than 2,000 milligrams of sodium per day.
The maximum rate of correction should be 8 mEq/L in any 24-hour period [12,18-20]. In general, the same rate of rise can be continued on subsequent days until the sodium is normal or near normal.
The test is available as an at-home kit, though the collected sample will typically be urine, not blood.
Amount needed to increase serum sodium level by 1 meq/l/hr= 0.6 x 70kg x 1.0= 42 meq/hr (safe rate for this patient).
For 0.9% Sodium Chloride Injection, USP, each 100 mL contains 900 mg sodium chloride in water for injection. Electrolytes per 1000 mL: sodium 154 mEq; chloride 154 mEq.
If necessary, you can increase the rate of fluid administration, or you can give the fluid at the same rate for a longer period, to achieve adequate rehydration. If hydration is not improving, give fluids more rapidly; the patient may need 200 ml/kg or more of intravenous fluids during the first 24 hours of treatment.
Saline 0.9% was compared to saline 0.45%. The risk of hypernatremia using saline 0.9% was significantly lower (2%) than the risk of hyponatremia using saline 0.45% (15%), and hyponatremia is a relevant issue in intensive care units.
On the surface, it is easy to think that giving normal saline (154 mEq/L) to a patient with hyponatremia from SIADH will help raise the serum sodium. But in the case of SIADH, giving normal saline will actually lower the serum sodium even more.
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 much is 150 mEq sodium?
Higher levels of sodium are normally associated with hypertension. A sodium level of 150 mEq/L (3.45 mg/ml) or more is known as hypernatremia, a condition that is commonly caused by dehydration or eating too much salt.
On average, 1 mL/kg of 3% sodium chloride raises the serum sodium concentration by 1 mEq/L. Alternatively, 0.5 to 3 mL/kg/hour continuous IV infusion (2 to 3 mL/kg/hour for those with active seizures or signs of brain herniation). Monitor serum sodium concentrations every 1 to 2 hours during infusion.

The body needs only a small amount of sodium (less than 500 milligrams per day) to function properly. That's a mere smidgen — the amount in less than ¼ teaspoon. Very few people come close to eating less than that amount. Plus, healthy kidneys are great at retaining the sodium that your body needs.
In patients with nephrolithiasis we generally recommend limiting daily sodium intake to a maximum of 3000 mg (approximately 130 mEq) [51].
Americans eat on average about 3,400 mg of sodium per day. However, the Dietary Guidelines for Americans recommends adults limit sodium intake to less than 2,300 mg per day—that's equal to about 1 teaspoon of table salt!

How do you calculate normal saline percentage?
- % w/v = g of solute/100 mL of solution.
- Example 1:
- Example 1:
- X % = 7.5 g NaCl/100 mL of solution.
- X/100 = 7.5/100.
- 100X = 750.
- X = 7.5% w/v.
The physician has ordered D5W 1200 milliliters in 12 hours using 15 drops per milliliter infusion rate. What is the IV infusion rate in drops per minute? Step 1: Convert 12 hours into minutes. 12 hrs x 60 min/hr = 720 min Step 2: Use the formula above to calculate the IV infusion rate.
Three-percent sodium chloride (3% NaCl) is a hyperosmolar agent used to treat hyponatremic encephalopathy or other cases of increased intracranial pressure. A barrier to the use of 3% NaCl is the perceived risk of local infusion reactions when administered through a peripheral vein.
Each mL of Sodium Chloride Concentrated Injection 20% contains 200 mg of sodium chloride which is equivalent to 3.4 mmol of sodium ions and 3.4 mmol of chloride ions.
Sodium Chloride 0.45% Solution for Infusion is indicated for the treatment of hypertonic extracellular dehydration or hypovolaemia in cases where the intake of fluids and electrolytes by normal routes is not possible. It can also be used as a vehicle or diluent of compatible medicinal products.

It indicates the chemical activity, or combining power, of an element relative to the activity of 1 mg of hydrogen. Thus, 1 mEq is represented by 1 mg of hydrogen (1 mole) or 23 mg of Na+, 39 mg of K+, etc.
The maximum rate of correction should be 8 mEq/L in any 24-hour period [12,18-20]. In general, the same rate of rise can be continued on subsequent days until the sodium is normal or near normal.
The maximum sodium increase within the first 24 hours should not exceed 10 to 12 meq/liter or <20-25 meq/L over 48 hours. However, some sources state that faster infusion rates may be used in known acute conditions such as hyponatremia that has persisted for less than 24-48 hours.”).
Will half normal saline lower sodium?
Serum sodium concentrations decreased after the administration of 0.45% saline solutions, and after administrating 2 L of 0.9% saline, the serum sodium concentrations increased in patients with baseline serum sodium concentrations lower than 136 mEq/L.
Daily maintenance fluid requirements (as per NICE guidelines): 25-30 ml/kg/day of water and. approximately 1 mmol/kg/day of potassium, sodium and chloride and. approximately 50-100 g/day of glucose to limit starvation ketosis (however note this will not address the patient's nutritional needs)
