Administration

  • Type: Osmotherapy, electrolyte/IVF
  • Dosage Forms:
    • 3% (513mEq/L)
    • 5% (856mEq/L)
    • 23.4% (4000mEq/L)
  • Nebulized (as adjunct for bronchiolitis, cystic fibrosis)

Adult Dosing

Symptomatic Hyponatremia

  • Bolus 100-250mL 3% NS 100cc bolus over 10min; repeat after 10min x1 if no improvement

Elevated ICP

  • Most studies used 250 mL bolus of 7.5% HTS with dextran[1]
  • Initial 250mL bolus of 3% will reduce ICP and can be delivered through a peripheral line
  • Target Na 145-155 meq/dL

Pediatric Dosing

  • Symptomatic hyponatremia: 2mL/kg of 3% over 10-60 minutes, repeat of up to 3 times
  • Elevated ICP
    • 3% NS: 3-10 mL/kg over 10-60 minutes[2]
    • Titrate to serum Na 145-150

Special Populations

Renal Dosing

  • Adult:
  • Pediatric:

Hepatic Dosing

  • Adult:
  • Pediatric:

Contraindications

  • Allergy to class/drug
  • Hypernatremia
  • Chronic hyponatremia
  • Severe CHF (theoretical), volume overload

Adverse Reactions

Serious

  • Hypotension(infusion rate-related)
  • Metabolic acidosis
  • Hypernatraemia
  • Hypokalemia
  • Volume overload
  • Renal failure
  • Coagulopathy
  • Phlebitis, tissue necrosis if extravasates (need central line for concentrations >3%
  • If Na+ corrected too quickly, central pontine myelinosis, seizure, encephalopathy
