Sodium Chloride 0.45% & Dextrose 5% Injection

Category: Intravenous fluid / Electrolyte and energy solution
Form: Sterile solution for intravenous (IV) infusion

Composition:

• Sodium chloride (NaCl) 0.45% – provides moderate sodium and chloride replacement.

• Dextrose 5% (D5W) – provides 5 grams of glucose per 100 mL of solution for energy.

• Water for injection as the solvent.

Uses:

• Fluid and electrolyte replacement in patients with mild to moderate sodium loss.

• Provides calories via dextrose to prevent catabolism in patients who cannot take adequate oral nutrition.

• Used as a maintenance fluid in patients requiring both hydration and energy supply.

• Can act as a carrier solution for intravenous medications.

Mechanism of Action:

• Sodium chloride helps maintain extracellular fluid volume and osmotic balance.

• Dextrose supplies energy and reduces protein breakdown by providing glucose.

• Being hypotonic to isotonic relative to plasma, it helps replenish both intracellular and extracellular fluids.

Administration:

• Administered intravenously, with rate and volume determined by patient weight, clinical condition, and fluid requirements.

• Monitor blood glucose and electrolyte levels, especially during prolonged infusion.

Side Effects:

• Hyperglycemia, particularly in diabetic patients.

• Fluid overload, which may lead to edema or pulmonary congestion in patients with heart or kidney issues.

• Rare electrolyte imbalances if improperly administered.

• Local irritation at injection site may occur rarely.

Precautions:

• Use cautiously in patients with diabetes, heart failure, kidney impairment, or electrolyte disturbances.

• Monitor fluid balance, electrolytes, and blood glucose during therapy.

• Adjust infusion rate to prevent fluid or electrolyte overload.

Summary:
Sodium Chloride 0.45% & Dextrose 5% Injection is a hypotonic intravenous fluid that provides moderate sodium and chloride along with glucose for energy. It is used for maintenance therapy, mild-to-moderate hydration, and calorie supplementation in patients unable to take adequate oral nutrition. Administered intravenously, careful monitoring of blood glucose, fluid balance, and electrolytes is essential, especially in patients with diabetes, kidney, or heart conditions.
