📋 Clinical Overview

A sterile, non-pyrogenic, isotonic solution for intravenous administration. It provides a source of free water, calories (from dextrose), and electrolytes (sodium and chloride ions) to correct fluid and electrolyte imbalances, maintain hydration, and serve as a vehicle for intravenous drug administration. The 5% dextrose component provides approximately 170 kcal/L, while the sodium chloride (0.45%) provides a hypotonic saline solution.

💊 Dosage & Administration

Adult: Highly individualized. Typical maintenance: 1500-2500 mL per 24 hours. Rate: 1-2 mL/kg/hr. Must be calculated based on body weight, clinical condition, and ongoing losses.

Note: For intravenous use only. Must be administered using sterile technique. Use a clean, non-pyrogenic infusion set. Check for clarity, particulate matter, and container integrity before use. Do not connect flexible plastic containers in series. Do not use if leak is present. Rate of administration must be prescribed by a physician based on patient needs.

⚠️ Contraindications

Known hypersensitivity to dextrose or sodium chloride
Fluid overload states (e.g., pulmonary edema, congestive heart failure)
Clinically significant hypernatremia
Clinically significant hyperchloremia
Anuria

🔬 Mechanism of Action

This combination provides both free water and electrolytes. The dextrose (glucose) is metabolized to provide calories and energy, sparing body protein and preventing ketosis. The sodium chloride provides essential extracellular ions to maintain plasma osmolality, blood pressure, and acid-base balance. The final solution is hypotonic (approx. 280 mOsm/L), providing more free water than isotonic saline, which is useful for replacing ongoing water losses.

🤕 Side Effects

Fluid overload (if infused too rapidly)
Hyperglycemia (especially in diabetics or with high infusion rates)
Local infusion site reactions (pain, phlebitis, erythema)

🤰 Special Populations

Pregnancy: Category C (US FDA). Should be used only if clearly needed. No well-controlled studies in pregnant women. Dextrose crosses the placenta. Benefit should outweigh risk. Monitor fluid balance.

Driving: No effect. The infusion is administered in a clinical setting.

🔄 Drug Interactions

Insulin	Dextrose infusion may require adjustment of insulin dosage to maintain euglycemia.	Major
Corticosteroids (e.g., Dexamethasone, Prednisolone)	May cause hyperglycemia, requiring monitoring.	Moderate
Diuretics (e.g., Furosemide)	May alter electrolyte balance; synergistic effect on sodium/potassium excretion.	Moderate
Lithium	Sodium loading may decrease lithium reabsorption, reducing its serum levels.	Moderate
Blood Products	Should not be administered simultaneously through the same IV line unless compatibility is confirmed.	Major
