Drug Guide
Calcium Chloride, Dextrose, Magnesium Sulfate, Potassium Chloride, Sodium Bicarbonate, Sodium Chloride, Sodium Phosphate, Dibasic, Heptahydrate
Classification
Therapeutic: Electrolyte replacement and correction of electrolyte imbalances
Pharmacological: Electrolyte and acid-base regulators
FDA Approved Indications
- Electrolyte replenishment
- Treatment of hypocalcemia
- Treatment of hypokalemia
- Treatment of hypomagnesemia
- Treatment of metabolic acidosis
- Management of certain cardiac arrhythmias
Mechanism of Action
Provides essential electrolytes and bicarbonate to restore or maintain normal electrolyte and acid-base balance in the body.
Dosage and Administration
Adult: Dose varies based on clinical condition; typically administered intravenously with careful monitoring. For example, calcium chloride: 1 g over 10 minutes for severe hypocalcemia.
Pediatric: Dose varies based on age and weight; often weight-based infusion. Consult pediatric dosing guidelines.
Geriatric: Adjust dose based on renal function and electrolyte levels; monitor closely.
Renal Impairment: Use cautiously; monitor electrolyte levels closely.
Hepatic Impairment: No specific adjustment; monitor levels and patient response.
Pharmacokinetics
Absorption: Administered intravenously; bioavailability is 100%.
Distribution: Distributed throughout extracellular fluid; crosses cell membranes to a lesser extent.
Metabolism: Not metabolized; electrolytes are used in various metabolic processes.
Excretion: Excreted primarily via the kidneys.
Half Life: Variable depending on the specific compound and renal function.
Contraindications
- Hypercalcemia
- Hyperkalemia
- Hypermagnesemia
- Severe renal impairment
- Digoxin toxicity
Precautions
- Monitor electrolyte levels frequently during administration.
- Use cautiously in patients with cardiac conditions, renal impairment, or those on digitalis.
Adverse Reactions - Common
- Phlebitis at infusion site (Common)
- Local pain or burning (Common)
Adverse Reactions - Serious
- Cardiac arrhythmias (Rare)
- Hyperkalemia or hypercalcemia (Rare)
- Extravasation leading to tissue necrosis (Rare)
Drug-Drug Interactions
- Digoxin (can cause toxicity with alterations in calcium or potassium levels)
- Other nephrotoxic drugs
Drug-Food Interactions
N/ADrug-Herb Interactions
N/ANursing Implications
Assessment: Monitor electrolyte levels (calcium, potassium, magnesium, bicarbonate), cardiac status, and renal function before and during infusion.
Diagnoses:
- Risk for electrolyte imbalance
- Risk for tissue injury at infusion site
Implementation: Administer slowly, with infusion rate adjusted based on patient response and laboratory results.
Evaluation: Evaluate clinical response and electrolytes; adjust dosing accordingly.
Patient/Family Teaching
- Understand the purpose of the infusion and potential side effects.
- Report any pain, swelling, or redness at the infusion site.
- Follow instructions for any additional medications or dietary restrictions.
Special Considerations
Black Box Warnings: N/A
Genetic Factors: None established.
Lab Test Interference: Electrolyte solutions can affect serum electrolyte measurements.
Overdose Management
Signs/Symptoms: Hypercalcemia, hyperkalemia, arrhythmias, tissue necrosis.
Treatment: Discontinue infusion, provide supportive care, and administer specific antidotes if indicated (e.g., calcium chelators).
Storage and Handling
Storage: Store at controlled room temperature away from light.
Stability: Stable until expiration date; must be inspected for particulate matter and discoloration before use.
