Multiple Electrolyte ‘G’ and Dextrose Injection is an intravenous fluid formulation used to correct electrolyte imbalances, provide energy, and maintain hydration in patients unable to take sufficient fluids orally. It combines essential electrolytes with glucose to support metabolic needs.

Here are the key details:

1. Composition and Form

• Electrolytes (Multiple Electrolyte ‘G’):

  • Sodium (Na⁺)

  • Potassium (K⁺)

  • Calcium (Ca²⁺)

  • Magnesium (Mg²⁺)

  • Chloride (Cl⁻)

  • Phosphate (PO₄³⁻)

• Dextrose: 5% w/v (provides energy and helps maintain osmotic balance).

• Supplied as a sterile intravenous solution in bags or bottles.

2. Mechanism of Action

• Electrolytes: Replenish deficiencies, maintain osmotic balance, and support neuromuscular and cardiovascular functions.

• Dextrose: Provides caloric support and helps in the transport of electrolytes into cells.

• Corrects fluid and electrolyte imbalances while supplying energy for metabolism.

3. Indications

• Fluid and electrolyte replacement in dehydration or imbalances due to:

  • Vomiting, diarrhea, or excessive sweating.

  • Burns or trauma.

  • Surgery or critical illness.

• Nutritional support when oral intake is insufficient.

• Adjunct therapy in certain metabolic disorders requiring electrolyte correction.

4. Administration

• Administered intravenously under medical supervision.

• Infusion rate and volume depend on:

  • Patient’s age, weight, and clinical condition.

  • Severity of dehydration or electrolyte imbalance.

• Continuous monitoring of vital signs and urine output is recommended.

5. Side Effects

Common:

• Mild local irritation at infusion site.

• Electrolyte-related effects if infused too rapidly.

Serious:

• Hypernatremia or hyponatremia (sodium imbalance).

• Hyperkalemia or hypokalemia (potassium imbalance).

• Hyperglycemia (due to dextrose).

• Fluid overload, especially in patients with heart or kidney disease.

• Rare allergic reactions.

6. Contraindications

• Known hypersensitivity to any component of the solution.

• Severe hypernatremia, hyperkalemia, or fluid overload states.

• Certain metabolic disorders where specific electrolytes are contraindicated.

7. Precautions

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

• Adjust infusion rate in patients with renal or cardiac impairment.

• Use caution in elderly patients or those with restricted fluid tolerance.

• Avoid rapid infusion to prevent cardiovascular or neurological complications.

8. Storage

• Store at controlled room temperature, protected from light.

• Do not freeze.

• Use aseptically and discard any unused portion according to guidelines.
