Overview

â„šī¸

What is this medicine?

This medication is an intravenous (IV) fluid, meaning it's given directly into your vein. It's a special type of fluid that provides your body with water, sugar (dextrose), and important salts (electrolytes) like sodium, potassium, and magnesium. It's used to help keep your body's fluid and salt levels balanced, especially when you can't drink enough or are losing fluids due to illness, surgery, or other conditions. The sugar provides a small amount of energy.

Available Forms & Alternatives

Dosing & Administration

đŸ‘¨â€âš•ī¸

Adult Dosing

Standard Dose: Maintenance fluid: Typically 1.5 to 2.5 liters per 24 hours, or 25-40 mL/kg/day, adjusted based on patient's fluid and electrolyte status, metabolic needs, and clinical condition. Infusion rate is usually 60-100 mL/hour.
Dose Range: 60 - 100 mg

Condition-Specific Dosing:

dehydration: Higher initial rates may be used for rehydration, followed by maintenance.
cardiac_renal_impairment: Lower rates and careful monitoring to avoid fluid overload.
đŸ‘ļ

Pediatric Dosing

Neonatal: Not established (specific neonatal formulations are preferred; careful monitoring of glucose and electrolytes is critical).
Infant: Calculated based on body weight (e.g., Holliday-Segar method: 100 mL/kg for first 10 kg, 50 mL/kg for next 10 kg, 20 mL/kg for subsequent kg per 24 hours).
Child: Calculated based on body weight (e.g., Holliday-Segar method).
Adolescent: Calculated based on body weight, approaching adult dosing for larger adolescents.
âš•ī¸

Dose Adjustments

Renal Impairment:

Mild: Use with caution; monitor electrolytes (especially potassium, magnesium, phosphate) and fluid balance closely.
Moderate: Reduced infusion rate and/or adjustment of electrolyte content (e.g., lower potassium, magnesium) may be necessary. Close monitoring is essential.
Severe: Contraindicated in anuria. Use with extreme caution and significant reduction in volume and electrolyte content (especially potassium, magnesium, phosphate). May require specific electrolyte-free solutions or dialysis.
Dialysis: Fluid and electrolyte administration must be carefully managed in conjunction with dialysis prescription. Often, specific electrolyte-free solutions are preferred, or solutions tailored to post-dialysis needs.

Hepatic Impairment:

Mild: Generally no specific adjustment, but monitor for fluid overload if ascites is present.
Moderate: Monitor for fluid overload and electrolyte imbalances. Acetate/lactate components are generally well-metabolized unless severe liver failure.
Severe: Use with caution; monitor for fluid overload, electrolyte imbalances, and potential for lactic acidosis if lactate is present and liver function is severely compromised.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Ionosol-Mb D5W provides water, dextrose (carbohydrate source), and essential electrolytes (sodium, potassium, magnesium, chloride, phosphate, and a bicarbonate precursor like acetate/lactate) to maintain fluid and electrolyte balance, prevent dehydration, and provide minimal caloric support. Dextrose is metabolized to provide energy and reduce protein catabolism, while electrolytes are crucial for various physiological functions, including nerve impulse transmission, muscle contraction, and maintaining osmotic pressure.
📊

Pharmacokinetics

Absorption:

Bioavailability: 100% (intravenous administration)
Tmax: Not applicable (continuously infused)
FoodEffect: Not applicable (intravenous administration)

Distribution:

Vd: Distributes throughout total body water compartments (intracellular and extracellular fluid). Dextrose is rapidly distributed and metabolized.
ProteinBinding: Not applicable (electrolytes and dextrose do not significantly bind to plasma proteins in this context).
CnssPenetration: Yes (water and electrolytes cross the blood-brain barrier; dextrose crosses via glucose transporters).

Elimination:

HalfLife: Variable (depends on fluid and electrolyte balance, renal function, and metabolic rate; components are continuously utilized or excreted).
Clearance: Renal excretion for excess electrolytes and water. Dextrose is metabolized.
ExcretionRoute: Renal (water, excess electrolytes); Respiratory (CO2 from dextrose metabolism).
Unchanged: Not applicable (components are either metabolized or excreted as needed).
âąī¸

Pharmacodynamics

OnsetOfAction: Immediate (upon infusion)
PeakEffect: Rapid (as fluid and electrolytes distribute and dextrose is metabolized)
DurationOfAction: Continuous (as long as infusion is maintained)

Special Patient Groups

🤰

Pregnancy

Generally considered safe for use during pregnancy when clinically indicated for fluid and electrolyte maintenance. Careful monitoring of fluid balance and electrolytes is essential to prevent complications for both mother and fetus.

Trimester-Specific Risks:

First Trimester: No known specific risks, but fluid and electrolyte needs may change with nausea/vomiting.
Second Trimester: No known specific risks.
Third Trimester: No known specific risks, but monitor for fluid overload, especially in pre-eclampsia or cardiac conditions.
🤱

Lactation

Generally considered safe for use during lactation. The components (water, dextrose, electrolytes) are natural constituents of the body and breast milk. Infusion is unlikely to cause adverse effects in the breastfed infant.

Infant Risk: Low risk.
đŸ‘ļ

Pediatric Use

Pediatric patients, especially neonates and infants, have different fluid and electrolyte requirements and are more susceptible to fluid overload, electrolyte imbalances, and glucose fluctuations. Dosing must be precisely calculated based on weight and age (e.g., Holliday-Segar method), and close monitoring of fluid balance, electrolytes, and glucose is critical.

👴

Geriatric Use

Elderly patients may be more susceptible to fluid overload, electrolyte imbalances (especially hyponatremia), and renal impairment. Use with caution, initiate at lower rates, and monitor fluid status, electrolytes, and renal function closely.

Clinical Information

💎

Clinical Pearls

  • Ionosol-Mb D5W is a maintenance fluid, not a resuscitation fluid. It is hypotonic after dextrose metabolism and should not be used for rapid volume expansion in hypovolemic shock.
  • Always assess patient's baseline fluid and electrolyte status before initiating therapy.
  • Careful monitoring of intake and output, daily weights, and serum electrolytes is crucial to prevent fluid overload or electrolyte imbalances.
  • In patients with diabetes or glucose intolerance, blood glucose monitoring is essential due to the dextrose content.
  • Avoid rapid infusion, especially in patients with cardiac or renal impairment, to prevent fluid overload and pulmonary edema.
  • This solution contains potassium and magnesium; use with extreme caution or avoid in patients with hyperkalemia or hypermagnesemia, or severe renal impairment.
  • The 'Mb' in Ionosol-Mb refers to 'maintenance balance', indicating its suitability for ongoing fluid and electrolyte needs rather than acute deficit replacement.
🔄

Alternative Therapies

  • Oral rehydration solutions (for mild dehydration, if tolerated)
  • Other intravenous fluid types (e.g., Normal Saline (0.9% NaCl) for volume expansion, Lactated Ringer's for balanced electrolyte replacement, Dextrose 5% in Water (D5W) for free water and glucose)
  • Specific electrolyte supplements (e.g., potassium chloride, magnesium sulfate) for targeted correction of severe deficiencies.
