Drug Guide
Dextrose; Magnesium Acetate; Potassium Acetate; Sodium Chloride
Classification
Therapeutic: Intravenous fluid and electrolyte replacement
Pharmacological: Electrolyte solution and carbohydrate source
FDA Approved Indications
- Fluid and electrolyte replenishment in dehydration, electrolyte imbalance, and physiologic maintenance
Mechanism of Action
Provides essential electrolytes and glucose to correct deficits and maintain fluid balance in the body.
Dosage and Administration
Adult: As per physician’s orders, typically 100-200 mL/hr infusion rate, adjusted based on clinical condition.
Pediatric: Dosing individualized based on age, weight, and clinical need; consult pediatric dosing guidelines.
Geriatric: Adjust as necessary based on renal, hepatic function, and volume status.
Renal Impairment: Use with caution; monitor electrolyte levels and kidney function.
Hepatic Impairment: Use with caution; monitor for fluid overload and electrolyte imbalances.
Pharmacokinetics
Absorption: Immediately available for use after infusion; electrolytes distribute throughout body fluids.
Distribution: Electrolytes distribute widely within total body water.
Metabolism: Electrolytes are not metabolized, but used in various physiological processes.
Excretion: Excreted primarily by the kidneys.
Half Life: Dependent on renal function and volume of distribution.
Contraindications
- Hyperkalemia, hypernatremia, or hypermagnesemia
Precautions
- Monitor serum electrolytes closely during infusion; risk of fluid overload, especially in heart or renal failure.
Adverse Reactions - Common
- Phlebitis at infusion site (Occasional)
- Electrolyte imbalance (e.g., hyperkalemia, hypernatremia) (Uncommon)
Adverse Reactions - Serious
- Signs of fluid overload (dyspnea, edema) (Uncommon)
- Hypersensitivity reactions (Rare)
Drug-Drug Interactions
- Other nephrotoxic or electrolyte-altering agents
- Loop diuretics may increase risk of electrolyte imbalance
Drug-Food Interactions
N/ADrug-Herb Interactions
N/ANursing Implications
Assessment: Monitor vital signs, serum electrolytes, urine output, hydration status.
Diagnoses:
- Electrolyte imbalance
- Risk for fluid volume overload
Implementation: Administer via infusion pump; monitor site and patient response.
Evaluation: Check serum electrolytes and hydration status regularly; adjust infusion as needed.
Patient/Family Teaching
- Report any swelling, shortness of breath, irregular heartbeat.
- Understand the purpose of electrolyte replacement and the importance of monitoring.
Special Considerations
Black Box Warnings: N/A
Genetic Factors: N/A
Lab Test Interference: Electrolyte solutions can affect serum electrolyte measurements.
Overdose Management
Signs/Symptoms: Electrolyte disturbances such as hyperkalemia, hypernatremia, hypermagnesemia, fluid overload symptoms.
Treatment: Discontinue infusion, monitor electrolytes, provide supportive care, administer specific antagonists if indicated (e.g., calcium gluconate for hyperkalemia).
Storage and Handling
Storage: Store at room temperature, protected from light.
Stability: Stable under recommended storage conditions until the expiration date.
